Update on my nesting Northern Cardinals

An update on the cardinals nesting less than three feet from my kitchen window. Her lone egg hatched this morning, and in this photo (taken from my kitchen window this morning) the female is brooding the lone chick. While a clutch of two eggs is apparently not that unusual, at least for second nestings, one egg is. However, I think a cowbird may be the reason. I saw a female cowbird go to the nest - first time I've ever caught one in the act - but she didn't drop an egg then, as the cardinal had not yet laid any eggs.

However, at some point, probably after the cardinal laid her second egg, it returned. Cowbirds are known to shove a host species' egg from the nest and replace it with their own. That would have left one cardinal egg. However, something happened to the cowbird's egg, and it somehow disappeared. Hopefully the cardinal chick will now flourish.

This has been very interesting to watch at less than arm's length. While she did all the brooding, the male was quite attentive and brought her food. He also sings to her constantly, often from right above the nest. Female cardinals sing very well, and she would duet back and forth with him while incubating her egg. Now that the chick has popped out, he will be an equal partner in feeding it. While adult cardinals are primarily vegan, they feed nestlings an insect-rich diet - babies need the protein to grow. I saw both adults feeding the baby masticated insects this morning, even though it is a brand-new hatchling.

I live on a typical suburban lot, just over one-third of an acre. But my yard is awash in native flora - this nest is in a trumpet-creeper liana - and there are lots of shrubs and trees. It is an oasis in a sea of lawns mowed in diamond patterns that are overly treated by Chem-lawn and filled with nonnative species in overly manicured gardens. Thus far this year, in addition to the cardinals, I have hosted nesting Downy Woodpeckers, Blue Jays, Carolina Chickadees, Tufted Titmouse (probably), House Wrens, Carolina Wrens, Gray Catbirds, Eastern Bluebirds, American Robins (probably), Song Sparrows, Eastern Towhees (probably), and possibly other species. And scores of other species, including migrants and other species nesting elsewhere locally, use my yard frequently.
