Even when someone is able to locate a bird nest, that nest is usually in a location that does not allow for a good look inside; it may be in a tree cavity, high in a tree, or deep in a thicket. In my walks in Eliza Howell Park, I have, however, on occasion found nests that provide an opportunity to take a quick look – and quick camera snap – when the incubating adult is off the nest.
Note: Photos of the birds were all taken by Margaret Weber.
Barn Swallows regularly nest on little ledges under bridges and other structures. Their nests are mostly of mud, lined with softer material, including feathers. Cream-colored eggs, with dark splotches, represent a fairly common pattern among bird eggs. Each species, though, is a little different in size and coloring, in addition to having quite different nests.
Bluebirds nest in cavities in trees or in nest boxes. Their practice of using nest boxes that humans provide has helped them recover from very low numbers a few decades ago and makes it possible sometimes to get a look at the eggs.
Song Sparrow nests are well hidden in grasses and weeds and shrubs, sometimes on the ground and sometimes up a little. They are very skilled at not going directly to their nest when someone (like me) is watching. This year is the first time I have found a Song Sparrow nest and it happened when I was walking through tall grasses and the sparrow flew out at my feet. I looked down, pulled out my phone for a quick picture, then left. The eggs are small and they do not all look exactly the same.
Catbirds nest in thickets and the few nests that I have seen over the years in Eliza Howell Park have been about 6 – 8 feet high. In my experience, the eggs that are only one color, not speckled or splotched, usually have no variation from one to another in the same clutch.
Often my pictures of the insides of bird nests are not great quality photos. One reason is that I take hurried pictures of bird eggs; I do not want to stress the adults. Though absent from the nest at this moment, they likely know of my presence and I want to be gone as quickly as possible. I have often returned some time later and watched from a safe distance. I have been pleased to note that, in every case, the incubating adult has been back on the nest after my one-time quick close-up.
