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.

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.)

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.

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.)

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.

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.

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.
