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.
