Again At Midsummer

Nearly a year ago I wrote a post about what was going on in my yard. In many ways things are the same and things are different this year.

Cherries in various stages of ripeness (Margo D. Beller)

After the house wren family dispersed, I waited to see if another wren would use the nest box. It took five days - not one like last year - for a male to investigate and start singing around my yard. But nothing much happened. No female showed up. Several times the wren would fly to the box but then would leave.

Finally, I investigated. I found the opening to the box was plugged with nesting material for a house sparrow. Neither the nest nor the sparrow would be able to fit through the small opening so the bird gave up. I knew it was a house sparrow because of the nest material. House wrens use twigs. According to the bird experts at Cornell, house sparrows use "coarse dried vegetation, often stuffed into the hole until it’s nearly filled. The birds then use finer material, including feathers, string, and paper, for the lining." They also steal other birds' nests for their own.

I pulled the mess out of the opening but by then it was too late. It takes many weeks for a wren to find a mate, for her to sit on the eggs and raise the young. Southbound migration is only a month or so away. I've heard no  house wren song in my yard, tho' I've heard them elsewhere. I'll take the nest box down soon.

One of many robins in the cherry tree (Margo D. Beller)

Last year the apple tree did not lose its leaves for some time. This year its yellowed leaves are scattered below. The last apple was taken by a squirrel near the middle of June, nearly a month earlier than in the past. The tree survived its surgery but has been hit, as has the rest of my garden, with high winds, searing heat, thick humidity, the occasional flooding downpour and, now, wildfire smoke. Unlike me, it was not affected by the nearly three days we were without power over the July 4 weekend because of hurricane-force winds and hours of rain. Global warming? You be the judge.

The heat and humidity has kept me from doing much in the way of gardening, and the weeds have been taking advantage. But also taking advantage is a cherry tree at the edge of my yard.

I didn't plant this tree. I don't know if a previous owner did or if it sprang up from a dropped seed. This tree's growth was blocked for years by a nearby apple tree and the giant ash tree, both of which I cut down for different reasons. Once those trees were gone the cherry tree got plenty of light and so jumped in height and spread out. This year it was covered in flowers and now is covered in cherries. These are small and sour (yes, I tried a few) and the families of grackles, robins, catbirds and other fruit-eating birds love them.

The nearby viburnum's berries are currently green but will, I hope, soon turn red. So will the dogwood's fruit. The privet shrubs will soon have their own berries. All of these will feed the birds as they get ready to head south for the winter.

It is hard to believe some birds are already migrating, such as male hummingbirds - which is why the trumpet vines and jewelweeds are flowering for them. At my house I've twice caught sight of a hummingbird investigating flowers but no birds have been inclined to use the feeder I have out, as far as I know.

There are plenty of birds that breed in my area, meaning their spring migration north stopped in my yard or in local parks that provided them with food, water and a protected place to breed. Hearing them singing or flying around gives me something to enjoy when I go out early in the morning nowadays. And there are plenty of fruiting and seeding plants out there - including weeds - that will feed those birds and the others later in the summer when it's time for them to leave.

So Many Babies

The catbird sat on the branch just below the wren nest box. It surveyed the ground below, looking for movement of a worm or insect. Then it flew down to nab its meal.

While it sat there, no house wren came out to chase it from the nest. For the first time in weeks the box was empty. 

Wren nest box, June 2026 (Margo D. Beller)

For the second straight year, after years of just missing, I saw the house wren chicks leave the nest and take their first wobbly flight to where a parent was no doubt calling for it. I was on my porch so I could not hear the parent, but I could see the three chicks as, one by one, they flew to the bare part of a dogwood branch. Each fluttered to keep its balance. One by one each moved to the leaves at the end of the branch and flew in the direction of the blue spruce's boughs.

This was a change. In past years, the wrens would fly in the other direction, to the shrubbery behind the flood wall. But this year a new neighbor had moved in and put up a wall so his dog could run in the yard. While he had put the fence well in from the property line to leave the trees and shrubs standing, the wall might've made the area too confining to the parents. So they led their young to Spruce, who had told me when the male first investigated the box in mid-April.

"They were here, Margo," he told me now, "but soon they all flew down to the ferns you have growing near me. I couldn't see them in the foliage. They might've flown behind your fencing."

This was on Tuesday, June 16, a week after my last post. In the interval the young had grown so big they could only be fed from outside the box. It was only a matter of time before they flew, I thought. And so, again, I was right.

I have not heard any of the wrens in the yard since then but there have been plenty of baby birds calling after their parents to be fed: cardinal, chipping sparrow, catbird, robin, starling, grackle, titmouse. But the yard is different without the sound of a singing house wren.

This fawn from several Junes ago was in the backyard,
under the apple tree and away from the street.
(Margo D. Beller)

Last year the box was empty only a day before another, or possibly the same, male claimed it and started singing. This year there have been no new takers as yet.

Meanwhile, in late May a doe appeared in the backyard nearly every morning, mainly eating weeds in that sheltered area behind the flood wall. I told my husband and MH's immediate comment was, "Is she pregnant?"

Memorial Day to early June seems to be the time when pregnant does give birth to one, two, sometimes three fawns. The fawns are hidden at first, spending their time sleeping like any newborn, surviving on mother's milk. We have found sleeping newborns in the yard in past years. So I understood his question. No, I said.

But I figured there was a fawn somewhere nearby. After a few weeks it would start following Mom around and supplement its milk diet with grass and plants. (A dangerous time for any unprotected plants as the young figures out what tastes good and what doesn't.)

The viburnum stands in front of the flood wall, with the fence
beyond. (Margo D. Beller)

So I was not surprised the other week when I found the fawn hunkered down in the area behind the flood wall. I couldn't see it from where I was sitting outside on the patio. But when first a chipmunk and then a squirrel climbed a tree and started their alarm calls, I went to see if a cat was hiding back there. Instead, there was the fawn. We stared at each other. When deer are small like this they look cute. It is when they grow and destroy my plants that I want to shoot them. (Same with baby Canada geese.)

Well, I said to it, at least your mother didn't leave you behind the deer netting where you'd make a mess trying to get out. (I now use an old garden hose to block the way in behind that fence.)

I moved and then the fawn bounded away in that herky-jerky way colts run, heading for Mom.

I figured Mom would not leave it there alone again and I was right. When I saw it behind the flood wall today, Mom was nearby, behind a privet bush. Both took off, going around the house next door, perhaps to the area where they'd have gone directly had the fence not been there. 

But they'll be back at some point. Whether house wrens are is another story.

House Wrens and a Sea of Green

With the exception of the viburnum, whose flower heads went from greenish yellow to bright white and have now faded before they will eventually produce red berries, all the trees and shrubs in my garden have lost their flowers. No more pink flowers on the dogwood or white blossoms on the apple and pear trees or yellow on the forsythia. The rhododendron and azalea flowers have shriveled and fallen. The irises have finished their bloom and so has the peony.

Viburnum flowers (Margo D. Beller)

Other perennials are now growing and will soon flower. The weeds are way ahead of them and I've already made several long, painful attempts to contain the spread by pulling what I can reach over, under and behind the deer fencing. 

For the most part my yard is a sea of green except where the clover is showing its white flowers in the grass. In the midst of this green sits the house wren nest box.

At this time of year what birds I find in my usual places have ended their migrations to nest and breed. Many of them now have young that need feeding. I hear the young birds calling for food and I see their parents zipping around, gleaning insects from tree leaves. The tree foliage is so thick now I can't see the birds well up there, I can only hear them unless they happen to come lower to hunt on the ground.

The house wrens living in my yard also have young. I estimate they have at least two, maybe three. I'm not sure when exactly the eggs hatched but Mom was in the box a lot at first and now both parents are flying back and forth from the box to remove waste and bring food. Last week the young were small enough for both parents to go inside the box at the same time but usually it is just Mom who goes in. If Dad brings food while she is in the box he gives it to her to give the young.

(I am not humanizing these birds, but it is easier to call them Mom and Dad than to keep saying "the female house wren," etc.)

This year's male house wren. (Margo D. Beller)

After Dad has delivered the food to the nest he sometimes goes to a higher branch in the dogwood and flutters. Then he sings. I don't know what the fluttering means. The singing is the only way I can tell male from female.

Soon the young will get so big both parents will feed them from outside the box, except when Mom squeezes inside to get the waste matter. Eventually, the chicks will be induced to leave the nest and try flying to their parents. With luck they'll make it to the safety of the thick shrubbery across from the box and eventually learn to feed themselves. Then the family will disperse.

Always, there are dangers.

So far this year I have shooed away house sparrows trying to reach into the box to destroy the eggs and take the nest for themselves. They are bigger than wrens so I knew they couldn't get past the small opening on the box to destroy any eggs. Still, I ran them off. I have also run off squirrels several times in the last week because I don't know if they are climbing the dogwood to find insects in the leaves or any fruits being formed or to grab a wren chick.

Until yesterday what I thought was the most horrifying attack I've seen on the nest box - and who knows how many I have missed - was the male red-bellied woodpecker that flew to the box and then stuck its long bill, and longer tongue, inside. At that point there were only eggs. I chased the bird off and later learned from an article that many types of woodpeckers, including the red-belly, eat baby bird brains. I can no longer hear a red-belly in my yard without apprehension.

But worse than that attack was the Cooper's hawk.

Another immature Cooper's hawk atop another feeder pole.
(Margo D. Beller)

Sitting on my enclosed porch with my coffee early in the morning, trying to wake up, I was horrified to see a hawk fly at the nest box as the parents were shuttling back and forth to feed their young. Based on the size I thought, "Cooper's hawk." After hitting the box it flew back to the nearby privet shrub. I ran out clapping my hands to scare it off. When it flew I realized the bird's wings were brown - an immature bird. (Adults have gray wings.)

As I stood near the dogwood after the hawk flew off I heard the cheeping of the wren young.

I went back to the porch and waited for at least one parent to return. After what seemed an eternity, Mom returned and zipped into the box, then left to get more grub. I did not hear the male. It will be much more difficult to feed all those young with only one parent, I thought. That happened several years ago when the male disappeared, the female did all the feeding and then a new male appeared to help her.

(Margo D. Beller)

I went out for a while to do some birding, not wanting to know if the juvenile Cooper's had succeeded in grabbing a meal. (Adult birds are usually much more successful than juveniles that are still learning to hunt.)

When I returned from my time away I went back to the porch, this time with my breakfast. And then I heard Dad. Then I saw Dad and Mom shuttling to the nest box to feed their young. 

The Cooper's had missed. It was as though the attack had never happened. 

This is what life is like for a bird - you migrate, you pick a territory, you find a mate and raise young. If you are lucky they will live to feed themselves, migrate, then come back next year - perhaps to the box I hang in the dogwood - and do it all over again. If a chick trying to fly falls to the ground a jay may grab it for a meal, as I've seen happen. The parents continue feeding what young remain. Do they mourn the loss? Mourning is a human concept. 

Life and death are everyday occurrences in nature. There is very little I can do, but I try to keep the cycle going in my yard.

For now I'm watching the nest box like a hawk.

'Dumb' Bird Watching

This very rainy morning I sat on my enclosed porch and watched the wren box. Even though the rain had weighed the dogwood branches down to obscure most of the box, I knew what was happening because I had seen the same activity yesterday when it was merely cloudy.

The female appears to be sitting on eggs.

The male house wren would start singing from a nearby bush and the female would pop out of the box to go get some food. The male would continue singing, now from the dogwood, until the female returned and went back in the box.

'Dumb' wren nest box (Margo D. Beller)

The dogwood doesn't have the thick canopy that was once in the apple tree, where the box once hung, but the wet does not stop the house wrens from going about their business in order to survive and bring up young. The male goes up in the tree to a branch where I can see it, sings until his mate returns, then flies to the shelter of the nearest bush.

I base my presumption that she is on eggs on many years of watching house wrens using this box I hung in the dogwood, where I can see it from my chair on the porch. But even then I can't be sure what is going on. 

When we returned from a recent family visit it looked like there was no female. The "tell-tale" sticks were no longer hanging beneath the box. Did the female that had been busily building the nest depart? I have no idea, but now there is a female - possibly the same one - and she is spending more time in the box because, I presume, there are eggs in the nest.

Had I one of those tiny cameras in the nest I'd be able to see inside. But I am not a fan of "smart" technology in general, and for birding in particular.

My Facebook feed, besides items from "Friends," will sometimes send up something based on some algorithm that says I enjoy seeing things about birds. I do, but I also get ads. A recent ad appeared for a "smart" bird feeder that would allow me to "watch birds live from your phone" and download photos and videos of every bird visit, among other talents.

(Margo D. Beller)

If there is one thing these old eyes don't need it is another reason to look at the small screen of my phone.

It is ironic that while I've been running around most mornings in these waning days of spring migration I've likely been missing "good" stuff in my own backyard. But when I am home I prefer to use my eyes and ears - albeit with some help from the Merlin app because I can't hear many calls anymore unless the bird is very loud or over my head. 

The idea of putting out a "smart" feeder that has some sort of camera in it allowing someone to see what's at the feeder every time a house sparrow or other bird shows up, even while that person is elsewhere, does not appeal to me. Too much information. Too much like one of those camera doorbells.

The birding world has come a long way from those intrepid people who would go out to distant places, see or hear something and then report back to Audubon. Merlin is helpful, yes. So is Cornell's eBird. But the social media channels - Instagram, Discord, etc. - where report of a rarity can draw hundreds of people in a pop-up flash - scare me. The coronavirus forced people outdoors, and while there they discovered birds. But binoculars and good pairs of eyes and ears are apparently not enough anymore.

Using 'dumb' technology
(RE Berg-Andersson)

I'm sure there are people out on this rainy morning looking for what migrants might still be around. But you won't find me going far from my porch.

Extreme Birding

My Facebook feed also brought me an article from NPR on three teenage boys who, with their fathers assisting them, competed in the World Series of Birding earlier this month.

My reaction to what I read was mixed. I was glad to see younger people getting involved with birding. There was a time, decades ago, when I was one of the younger ones in a group seeking out a bird. Now I'm right in there with the demographic. Birding needs younger blood.

However, I was sad to see there were no girls on the all-white team - not even a mother helping out - and I was horrified to read these kids were just as gung-ho competitive as the adults who were also running around the state trying to tick off as many birds on their list as they could in a day.

You're not seeing the birds when you are competing to see how much you can find in a day, you're seeing something - shape, sound - that allows you to claim you "saw" it and add it to your checklist.

I was amused the teenagers named their team the Pete Dunnelins, a play on the dunlin shorebird and Pete Dunne, who created the World Series of Birding as a charitable endeavor that would also contribute Citizen Science data on how well, or badly, bird species were doing in New Jersey.

The kids found 206 species of birds, but they came in second to a team that found 209.

The WSB is still an important way of recording what birds are where in a world where bird populations are in decline due to "development" and global warming, among other factors. 

But the WSB has gone way beyond its original intent. Now it is a competitive sport. The people at Cornell's Ornithology Lab - the ones behind Merlin and eBird - broadened the WSB to the world, calling it the Global Big Day. You have teams all over the world competing to find as many birds as possible. I imagine hundreds of people running into each other as they stomp on a marsh at 3 a.m. to hear grunting rails and soras, or whatever the global equivalents are.

I expect to see the WSB become part of the next X Games on television soon enough. 

No thank you.

My Big Days

The annual World Series of Birding is on Saturday, May 9, this year. 

Ornithologist Ludlow Griscom and his protege, Roger Tory Peterson of the influential field guides, were among the first to popularize using binoculars rather than guns to study birds in the field. They were also among the first to popularize the concept of the Big Day.

(RE Berg-Andersson)

The Big Day is a sort of endurance test - how many different types of birds can a person see in a day. It is a very American thing to do to prove to others (and yourself) just how good you are in finding and identifying birds. Some Big Days take place in popular places such as New York's Central Park and Van Cortlandt Park in the Bronx. Others can take place in your backyard.

Others take it to extremes, such as the three birders whose quest to see as many birds as possible in a year was made into a book and then a movie. Birding thus became another extreme sport instead of the walk in the park I enjoy. As I've said elsewhere, this isn't birding, it's listing. The bird's beauty is ignored, it is just a name ticked off on a chart.

Pete Dunne - not an ornithologist by his own admission - came up with the idea of marrying the Big Day with promoting citizen science. He called it the World Series of Birding, and it really took off when he got Roger Tory Peterson to come to Cape May, N.J., and ride with him and his team. 

The birds recorded during the World Series are reported to the organizations that study birds, including Cornell's Ornithology Lab and Audubon. This way they know which birds are thriving and where, and which are in decline.

But then nature- or conservation-oriented organizations realized a way to, in effect, cash in on the World Series in the name of citizen science. They asked people to donate funds based on how many birds the organizations' teams found, either per bird or in total. The funds would go to support the organizations' work. 

One example is the Land Conservancy of New Jersey, of which I am a member. I got the mailing below.

(Margo D. Beller)

The concept has become so popular the Cornell people expanded it to the world - literally. There is now a Global Big Day on the same day as the World Series of Birding.

As usual, this birder flies solo. I don't count the number of particular birds I find and I like to walk alone quietly. I avoid birding on the Saturday of the World Series because I don't want to run into teams of people rushing through with their checklists in an area where I am trying to bird.

However, early May is the height of northbound migration, when the birds are heading to their breeding territories. Now that I am retired I have the time to go out on a weekday morning and avoid the weekend birders. Thus I have been undergoing my own endurance test for the past two weeks, rising early most weekdays to visit some of my favorite places within easy driving distance (mindful of the rush hour traffic I will hit on the way home). 

One day is my own version of the "World Series of Birding" and it usually takes place in early May. That is when my husband (MH) drives us to the western edge of New Jersey, where the Delaware River flows, and we change places so I can slowly drive along Old Mine Road, an area of forest and high elevation. Many of the birds I want to see nest in this area and they all are singing as they proclaim their territories in preparation for mating and raising a brood. 

This place draws a large number of birds that would otherwise not be found elsewhere in New Jersey, as well as a large number of birders. 

A remnant of the former community on Old Mine Road
(RE Berg-Andersson)

There used to be homes along this road. But after too many floods the federal government decided there should be a dam across what is now Tocks Island. There was controversy over the dam, but unlike the fight to preserve Great Swamp from becoming an airport this fight was not successful for most of the people. They had to move, leaving their homes to be flooded.

Except the project was shelved in 1975, deemed too expensive. You can still see many of the abandoned homes, windows broken, covered in graffiti, on the verge of falling down like the barn shown above. (That picture is from a few years ago; as of May 4, 2026, more of the barn has come down). The homes of those who continued fighting to stay were grandfathered into the national park.

In summer people flock to this area where once there was a community to swim in the river or picnic. MH and I come before it gets too hot, buggy and crowded. During Covid, when very few federal parks were open, Old Mine Road was very popular. Lots were completely packed. At one the cars nearly spilled out into the road. 

That lot and several others are now blocked, no doubt because of erosion on the paths leading to the river that was caused by hundreds of pairs of feet.

Old Mine Road is where I do all the bad driving I accuse others of doing on the highways. Right hand on the wheel, left hand holding Merlin near the open window, stopping suddenly every time I hear something. MH knows I am going to do this and only grows testy when he wants me to pull over for the sandwiches I packed for lunch. 

Eventually, my stamina falters and I drive a little faster to get to the end. My head says to stop at every dirt path to hear what birds are around, but my body (and MH) tells me it is getting late. Five hours on one stretch of road goes by amazingly fast.

Near the end of the road we stop and MH takes over the driving.

Intrepid birder (me) on Old Mine Road a few years ago
(RE Berg-Andersson)

I enjoy all the birds I have found during these past two weeks, particularly the mornings after "big flight" nights when southwest winds and lack of rain brought thousands of birds northward. But finding the colorful challenges known as warblers is the main reason I go out in the early dawn hours in May.

This year at Old Mine Road the big search was for a Swainson's warbler - a bird of the south that prefers to stay low in brush where no one can see it. (I saw one - blink and you'll miss it - when we were in Florida in 2010.) We stopped at the stakeout but, as I expected, we allegedly "just missed it" because it was now deep in the brush off the road. But I heard something I had come to hear - the Cerulean warbler. As the name implies it is sky blue. It is also a bird, like too many others, whose population has declined due to habitat loss. 

Usually we are lucky if we can hear the buzzy trill of one Cerulean. This year we heard six. That made our trip a very Big Day for me. 

And Then There Were Two

Since my last post I haven't spent much time in the yard because it is migration time. I've risen early and gone places at various distances from my home, usually without eating. The early birder gets the birds as they look for food. Then I come home around 9 a.m. for my own breakfast. In good weather I take my food out to my enclosed porch and sit so I can watch the house wren nest box.

In a previous post I mentioned hearing the first house wren on April 19, 2025.  Exactly one year later, a male house wren started singing in the yard, two days after I put up the box. But things never seem to go as planned with these birds. After a day of seeing it around the box, the wren seemingly left.

Then, according to my notes, on Thursday, April 23, as I pulled the car out of the garage to go off one early morning, I heard a house wren singing very close, which meant it was on the opposite side of the yard from where the nest box hung. Was this the same wren or a different one?

The tell-tale stick telling other wrens this box is taken.
April 28, 2026 (Margo D. Beller)

I got my answer the next day when the house wren male continually sang from different parts of the yard as I ate my breakfast. Then it came to fuss over the box, bringing in a few sticks to give a prospective mate the idea that this would make a good spot for her nest. But I saw no second house wren that day and he soon left. 

On Saturday, April 25, it rained buckets for about 12 hours. The next day I could see the box had gotten plenty wet. I hoped it was dry inside. I saw no activity that day but I heard the male house wren singing almost continually, advertising his availability to any female.

Finally, on April 27, I saw a second wren come to the box. To me all house wrens look alike - they have no difference in size or color. The only way I could tell which was which was the male sat on a branch above the box and sang a bit while the female silently examined the box inside and outside. Then the two flew off together.

"So he has a mate," I thought. 

When I was next on the porch I saw the tell-tale stick coming out from the bottom of the box. That stick means that "this nest is taken."

This is far from new activity. I've been writing about house wrens since at least 2011. When I provide a box they have come every year, no matter which tree I securely hang it in. Every year they do the same thing - look at the box, decide to take the box, create a nest, defend it, raise young, leave with them once they can fly. To me this never gets old. 

Today, resting after hours of birding, I sat on the porch and watched the female furiously adding more sticks to the box. The male sang nearby as she worked on her nest. It is interesting to watch her bring a stick and then try to figure out how to get it into the box. Sometimes the stick is dropped. Sometimes it is broken. Eventually she figured out she can turn her head and put the stick in that way. 

I don't see the male as she does this but I can certainly hear him. He is still singing his loud territorial call. He'll continue to do that until eggs are laid. Then he will sing more softly so as not to call attention to the nest. To me it sounds like the call is intended to assure his mate he is around to defend the nest or tell her he'll watch things while she gets some food for herself.

This 2018 picture of the wren nest I cleared from the box
gives you an indication of what's in there, mainly done by the female.
(Margo D. Beller)

When she took a break from her nest-making labors she stood for a while on top of the nest box. She then flew down to nearby bushes where she can find what she needs, be it sticks or food. 

Every year when the nest is done and the wrens - which pair only for breeding and then separate - have gone south in the fall, I empty the box to clean it. Every year I am amazed at how tightly packed the stick nest is inside. The wrens usually have a brood of three chicks. That's a lot of birds jammed into what looks like a small box. But house wrens are small birds, particularly when just hatched.

Aside from those few sticks the male put in to "stage" the box, the female does all the work building the nest. He won't enter the box again except when the chicks are born and he helps her feed them and remove the poop.

She could be sitting on eggs as early as this weekend. And then things will really get interesting.

Spruce Makes a Discovery

Early in the morning the birds are calling. They are proclaiming their territories as they search for food and a mate. If that is when they call then that is when I go outside on my back patio with the Merlin app on my phone to hear what's out there.

Things continue to bloom in the garden. While the daffodils and forsythia have faded, the peony and lillies are growing, as are the hellebore's foliage, the spreading lily of the valley and the hostas in their pots. The andromeda bushes are covered in white bells the bees investigate, the apple tree I'm monitoring is covered in blossoms and the dogwood buds have opened to produce pink flowers for another year.

Unfortunately, the weeds are also flowering - garlic mustard, dandelions and, the bane of my existence, ground ivy. There are many others, including some growing in places it will be hard for me to get at.

Blooming andromeda bush (Margo D. Beller)

When I am walking around the yard with the phone I usually say good morning to Spruce Bringsgreen, the silver spruce we planted in 2007. Spruce is at his full height and, at 19, has been producing cones for the past ten years. 

This time, Spruce spoke first.

"Margo," he said, "this morning I saw there's a house wren going into the nest box!"

Yes, I said, I know. He's been singing in the yard since the day after my husband and I put the nest box into the dogwood. 

Blooming apple tree (Margo D. Beller)

This is our annual ritual, putting up a box to attract a pair of house wrens I can watch from my chair on the enclosed porch. I follow various bird lists for the first mention of house wren showing up in New Jersey. The closer it gets to my home county the more anxious I get to put up the nest box.

The box is usually visited quickly.

This year, right after putting it up, a pair of black-capped chickadees investigated. These birds are the only ones, aside from the house wren, small enough to get through the opening. But the birds, which usually nest in tree cavities, did not stay. That is just as well because a determined house wren will destroy a chickadee nest and take it over - I've seen that happen - just as a determined house sparrow would do the same thing to a house wren were it not too big to fit through the opening.

Blooming dogwood with nest box (Margo D. Beller)

One day after the box went up, I heard the distinctive house wren song. Two days after, a bird investigated. A day after that, the male wren brought a few sticks to the box - staging it, you might say, to interest a female wren. So far I have not seen more than the one wren in my yard but I'm sure that will change when the weather consistently warms and the winds come out of the south and blow more birds to my area.

"He's a little guy," Spruce said, "a bit smaller than what I've seen at the box before."

Perhaps, I said. According to the people at the Cornell Lab, a house wren is anywhere from 4.3 to 5.1 inches long. But, I added, I know that even if this wren is on the small side he will be just as feisty in protecting his territory.

"Yes, at first light he started singing up a storm. Real loud for such a small bird," Spruce added. "I hope he finds that mate."

Spruce and I will know how successful the house wren is soon enough.
