Life and Dying in the Backyard

Every spring I am surprised by my plants coming back after the winter. This year is no exception despite temperatures that reached the 80s in February and the 30s in April, with very little snow but lots of rain. Although some plants did not get as tall or as showy as usual, they did flower. The same is true of the trees and the shrubs. Both the apple and the pear trees have flowered, despite being severely cut back early this year. Where there are flowers there will be fruit, albeit fruit too high for me to easily pick.

This post will focus on one particular tree.

I have lived in my house for over 25 years. In my suburban neighborhood "woods" means trees on the property border. Any trees planted in the front or back yards have been put in by the homeowner. Over the years I've had to cut down yard trees for various reasons. I have, however, planted two trees - the blue spruce we nicknamed Spruce Bringsgreen and a flowering dogwood.

I planted the dogwood because in the fall it is supposed to produce red berries for the birds. Since that tree was planted in 2007 I've learned berries are not guaranteed. Like the other flowering plants, it depends on the weather. Some years there would be lovely pink flowers on the dogwood. But that did not necessarily mean berries would follow. Some years yes, some years no. The fresh green leaves would go red in the fall.

Since planting that tree I took it as a given that once established it would always be there. But like any other living thing, trees die. Sometimes they are killed by man, who cuts them down or pollutes the air. Sometimes they are killed by insects, as was the ash tree I had to cut down because of the emerald ash borer. Sometimes, however, they are killed by bacteria or fungus.

I don't remember when during the winter I first began to notice one branch was missing some of its bark but I did eventually notice, especially when more bare patches began to appear. I became alarmed when the apple and pear trees, the viburnum, the forsythia and the lilacs started leafing out and the dogwood remained bare. I thought the tree was dead.

I was going to write about it here. I even had a name for my post - Dead as a Dogwood.

But reports of the dogwood's demise were premature - after a recent heavy rain it started to leaf out.

Not everywhere, however. The part of the tree where the bark has come off remains bare, as are a few of the lower branches. 

I did some research into dogwood diseases, and to my horror discovered there are quite a few. The one that appears the closest to what is happening with this tree has the awful name of "crown canker."

Hoping for the best, I wrapped the lower part of the tree to prevent the bark that was just starting to flake from getting worse. I used my lopper on some of the lower branches and will have to use a saw or chainsaw on other parts. Because the tree went straight to leafing there will be no flowers. The leaves are small and I doubt there will be fruit. I don't even know if the tree will be alive next year.

As I looked at some of the pictures I've taken of this tree over the years I realize the signs were there: discoloring in the leaves, the irregular production of fruit. It was not until the bark started falling off that I realized this tree is sick. Should I have used the sprinkler last year instead of letting the grass go brown and deprive the tree roots of water during the summer drought? Should I have added more mulch to what I had already put down at the base of the tree?

I don't know. This year I'll use the sprinkler more and I'll use my saw on the dead branches. The tree may be disfigured but I hope it will recover. Or it may die. Living things die, even trees.

In the meantime, as I have for the past two years, I have put up the house wren nest box on one of the living dogwood branches. I heard a wren singing the other morning as I put out the feeders. The bird investigated the box, then flew to another yard. Will it be back? That, too, is unknown.

Christmas in October

Red and green are the traditional colors of Christmas. There are differing reasons why. According to one site I looked at, use of these colors dates back to the 1300s. As the site puts it, many believe the green represents the eternal life of Jesus while red symbolizes his shed blood.

However, a different site ties the red to advertising, specifically the suit Santa wore in Coca-Cola's first Christmas-themed print ad, which was extremely successful. The green is thought to be related to holly and other evergreens as part of the holiday's pagan past.

Right now, in October, you could say Christmas has come early for the birds.

The leaves of the viburnum in my backyard are a bright green, contrasting with the clusters of red berries that formed once the spring flowers faded. The same was true for the dogwood.

These fruits are important in the lives of the birds migrating south for the winter. When birds finish their overnight flights, they are very hungry and need food for the energy to continue their journeys. When it gets cold, insects are hard to come by unless they are pried out from under tree bark, as woodpeckers can do with their long, hard bills.

But for other birds, particularly fruit eaters such as robins, catbirds and cedar waxwings, my fruit-laden dogwood was like a big neon sign at a rest stop.

The overabundance of rain we've had for most of this year has been very good to the trees and shrubs. This year a black cherry tree at the edge of my property was laden with fruit. At a certain point in the late summer, robins would fly out from the nearby yew hedge and pick off the cherries, sometimes being very acrobatic in the process.

These cherries are long gone. Several weeks ago I noticed the dogwood was covered with red berries. I also noticed red was coming into the green leaves. Nothing much happened except for the leaves getting redder each day. 

And then, boom: A catbird appeared from a nearby shrub and flew into the tree and moved throughout, eating. So did cardinals and house finches that didn't feel like eating my sunflower seeds. One weekday morning, as I was finishing my coffee on the porch, I saw movement in the tree and saw a small bird flitting around that turned out to be a very special guest, a Tennessee warbler - a first for my yard! It was a one-day wonder. Soon flocks of robins started hitting the tree and now just about all the berries are gone.

How did the birds know when the dogwood berries were ripe enough to eat? I don't know but I do know when the leaves had turned completely red, that is when the most birds showed up. So there may be a connection.

Many plants fruit at this time of year. The yew hedge was filled with soft red berries eaten by birds and squirrels. The squirrels also seem partial to the small black berries that form in the privet shrubs. Crab apples are particularly prized by mockingbirds, robins and cedar waxwings.These are just a small sampling of plants whose fruits help birds during migration.  

And, of course, they also feed those birds that stick around for the winter, or those that stop their southbound flight in my area. So when the red berries of the viburnum ripen, perhaps after a few frosts, there will be food for the chickadees, titmice and other yard birds.

So these berry-producing plants (like the food from seed heads of spent flowers and weeds) are the gift that keeps on giving, both for the birds and me watching them.

Location, Location, Location

In the dawn's gray light, the house wren begins his bubbly, incessant territorial song. He is better than an alarm clock. I listen through the open window, thinking of how I had hoped to sleep in later. Then I remember, I am lucky to be hearing a wren singing at all.

Once again the changes in my yard came fast when winter was finally over. Where once the sun would hit me as I sat on my enclosed porch, now the light is filtered through oak and maple leaves. The sun's arc is now wide enough that my chair gets hit by the early and late sun. 

Besides the tree leaves, the shrubs, lawn and perennials came back with a vengeance. The back garden bed I had re-netted after taking off the protective burlap and cutting back the yew shrubs and the other plants quickly filled with fresh leaves and bright pink and purple flowers on the geraniums, coral bells and columbine. In the front yard, the azeleas, lillies and rhododendron were the best I've seen in years thanks to all the rain we had in the spring. Even Spruce Bringsgreen was covered in fresh blue-green foliage.

On May 7 I was still wrapping the pots of peppers I had put out front in plastic sheeting to protect them from the overnight cold. On May 9 we had a heavy rain. On May 10 the yard was filled with warblers, vireos and even a Swainson's thrush. All of them couldn't continue north to their breeding areas because of the bad weather. The birds were in my yard to take advantage of the oak seeds and insects. They fed and sang for only a day or so before continuing on their way.

But not all the migrants left. Some like to stay in my yard. Earlier this month there were still white-throated sparrows calling and singing their "Sam Peabody" song in my yard, where they had spent the winter. Then the catbirds started arriving. Now those sparrows are gone (but will be back next winter) and the catbirds fill the void with their activity and singing.

And then there is the migrant bird I watch for every year, the house wren. Every year I hang a wooden nest box in a tree, hoping a pair will use it to have a brood. Sometimes a wren pair will take over the nest box immediately. Some years it takes a little longer. 

Until this year the box was always hung in my apple tree. Last year I had planned on putting it in another location because when the tree is full of apples it is also full of squirrels, other birds and me trying to knock down as many apples as I can for my own use. The wrens would be disturbed. Two years ago there had been plenty of apples. 

But in 2020 I had forgotten my plan and hung the box in the apple tree as usual. However, in the year of the coronavirus the apple did not put out as many flowers to form fruit, so the picking was done by the time the wrens were feeding their young.

This year I did not forget, and I learned there are some differences using a dogwood instead of an apple tree.

Once I read the first reports of house wrens in my area I hung the box on what I thought was a sturdy branch. But the next strong wind had the box swinging wildly, something that didn't happen in the more densely branched apple tree. Luckily, the dogwood had another set of branches that made a natural V where the box could be hung more securely. 

Then I waited.

On May 4, I heard a house wren singing in the backyard. As I watched from the porch he investigated the box. Then he left. Later that day I was on the porch, looked at the box and was horrified to realize the hinged side that allows me to get in there to clear the nest after the birds have flown south for the winter was hanging open! I quickly got my ladder to climb up and shut the box tight so a bird would want to use it.

That's how things stood until May 9 when another house wren came singing into the yard. This one was more promising. He checked out all the feeders, flew into the dogwood and into the box. He stayed around the yard for a few days and at one point I heard the scolding call of his mate answering him. But on May 13 I realized there was no singing, no birds.

On May 15 I went to the box, intending to take it down and put it in the apple tree, even tho' this is shaping up to be another good year for apples. Then I saw the tell-tale twig sticking out from the box, signifying "this is taken." Was it from the pair? Would they be back? I left the box alone. But there was only silence for nearly a week.

On May 21, another male house wren was in the dogwood singing. He went into and out of the box and stayed in the yard all day. The next day he was back singing and his mate was making trips into the box with nesting material. Was this the pair from the other week? I don't know, but this time it looks like they are staying.

The dogwood leaves shade the box from the sun for most of the day (tho' the foliage is not as thick as it is in the apple tree) and the only things to possibly disturb the wrens are catbirds and others that happen to fly to a dogwood branch for some reason. Squirrels wouldn't be interested now, tho' they might be later in the season if there are dogwood fruits, which are small and red and won't be ripe enough to eat until after the wrens have finished their breeding and left the yard. Right now the squirrels are distracted by the apples that are growing and will soon be all over the yard, attracting deer.

As it was in the apple tree, the box is high enough in the dogwood to be free from danger while not so high that I have difficulty putting it up or taking it down. The box is sturdy despite years of dings. It is a good home in a very good location. 

That's why, as of today, Mr. Wren is still singing that bubbly, incessant song in the gray light of dawn.
