Backyard Nursery

The day after my last post, the house wrens fledged. I was working in my office and through the open window I heard one of the wren parents doing its scolding call from the tall arborvitae by the front door. I went downstairs, out the back door and around the house. I could see the bird moving around as it called. When I headed to the back door I could hear the young calling from the box or the shrubs across the way.

I'm no expert but I am thinking the parent was telling the young if they wanted to get fed they'd better fly out and follow him or her. And they did. Later that day I went out the front door and heard the wrens in the border hedge between my neighbor and me. One day after that, silence. They had left.

As usual, I was saddened by the silence. However, the adult house wrens had done what they were supposed to do: find a mate, find a nest site, build the nest, mate, lay eggs, sit on eggs and then feed the young when they hatch. When the young get big enough, encourage them to start flying and hunting on their own. Then, when the time is right, leave for the winter grounds until next spring.

My yard is not completely silent, however, There have been noisy bird families flying around for weeks now.

Robins, Suffolk County, NY (Margo D. Beller)

The young robins are as big as their parents, their red breasts speckled for camouflage. They are hunting insects in the lawns, every so often running over to Mom or Dad for a quick worm. Families of grackles and starlings dig into the lawn, too. Raucous titmice young are calling as they follow their parents in the treetops. Families of blue jays are scouring the apple tree for insects, a little harder for them with the apples gone. A family of cardinals, the young looking like their mother for now but with black bills, hunt in the trees, as does a family of flickers.

In the hot July air, male goldfinches are doing their swooping flight to impress the females. Goldfinches nest later than other birds because they depend on seeds to feed their young, and it takes a while for plants to go to seed.

And there are other young. I did not have a repeat of what happened in 2013 but the other day a doe ran through my yard followed by her two speckled fawns prancing like colts. They are lovely to watch, as long as they are leaving my property so they can't nibble on my plants. (A doe with young is a lot more skittish and ready to run if I confront them than when a doe is alone.)

And to bring the story full circle, a few days ago I was on the porch when a house wren appeared at the water dish, dipped its bill and then flew to the dogwood tree. As I watched it checked out the nest box inside and out. Then it flew to a shrub.

You'll recall it was a house wren that came to the water dish back in June that spurred me to put up the nest box, and then I waited for what seemed like years for a pair to come and use it, the pair whose young just fledged.

Was this recent bird one of those wrens coming back to the old homestead? One of the young? Or was it a completely different wren looking for a suitable place to start a second brood? I don't know. It has not returned but the box will remain out for the rest of the summer, just in case.  

Family Time, Again

She is nearly invisible in the messy cup nest she built at the top of my pear tree, her yellow bill showing as she raises her head to look at me. But I am behind glass on my enclosed porch and no threat to her. After taking about a week to put the nest together, she is sitting on three to five blue eggs and will rarely move off them for the next two weeks or so unless she must.

Like the neighborhood children freed from school to run around their yards and play, my yard is filled with the sound of noisy young, in this case birds.

Robin in my pear tree, July 13, 2019 (Margo D. Beller)

The American robin female in her nest is not the only robin in my yard. There are others flying around, many of them juveniles whose breasts are mottled rather than orange to help camouflage them. Their nest was in my large yew hedge. An adult male robin is feeding them. There could be two robin pairs or these juveniles may be an earlier brood of the same female robin in the pear tree. (Robins can have up to three broods, if conditions are right.)

This is the time of year when, if you are looking for them, you'll likely see birds either holding food for young or nesting materials. Those with food will lead you to squawking young, which, when they get a little bigger, will flock after their parents and make themselves very visible.

In my yard, besides the robins, the types of birds followed by young so far have included cardinal, flicker, chipping sparrow, starling, titmouse and grackle, with large flocks of cedar waxwings flying overhead. The other morning I watched a young grackle pull a worm from the grass beneath the apple tree. The bird is completely dull brown while an adult grackle is iridescent, with a bright yellow bill and eyes. When you are a young bird, you need all the help you can get to survive into adulthood.

back. It was well hid and protected by thorns. (Margo D. Beller)

Bigger birds - jays, gulls, great blue herons, crows - will eat baby birds, which is why you will often see these birds chased off by smaller birds - red-winged blackbirds, mockingbirds, Eastern kingbirds, for instance - protecting their young. Danger can come at any time from soaring raptors and neighbors' prowling cats.

Take the robin in my pear tree. According to the Cornell Ornithology Lab, on average "only 40 percent of nests successfully produce young. Only 25 percent of those fledged young survive to November. From that point on, about half of the robins alive in any year will make it to the next."  And robins are relatively big songbirds, about eight to 11 inches long. 

All these bird families passing through my yard are fascinating to watch. Small chipping sparrows land in the longish grass and seem to disappear except for the young's buzzy contact calls. Larger starlings stick with their parents as they hunt in the grass and in the winter will join with other family groups to create the huge flocks that seem to undulate in the air like a single organism. When the berries on my viburnums, dogwood and other shrubs are ready, the robins and other fruit-eating birds will feast (as will the squirrels). Then, when it turns cooler and the leaves start to fall and the insects die off, many of these birds will fly south to their winter grounds to eat there in preparation for next spring's migration and breeding.

male flew off to the flood wall. I am guessing he was watching things
while his mate was away. (Margo D. Beller)

Unlike in past years, I am not watching a house wren brood. The nest box I cleared a few weeks ago was visited by a singing male. I was hopeful. However, it didn't attract a mate and didn't build a nest. It used the box as a temporary roost for a few days and hasn't been seen since. But that's the nice thing about the natural world. While there are no house wrens this year, I have a front-row porch seat for when Mother Robin's eggs hatch.
