Eastern Bluebirds and Tree Swallows have been active in the meadows this spring.
I’ve devoted some of my permitted outdoor exercise to keeping check on the nest box trail I have been monitoring for nine years. A quick, no-flash photo, examined minutes later and several yards away, gives me a chance to get an extra good look at each nest box interior in order to assess chick age and condition and see if any intervention is needed, with less stress to the nestlings and worried adults.
To date, I have five nests on my trail with bluebird nestlings. The first Tree Swallow eggs of the season appeared this week. Enjoy a look inside a few bluebird nests.
Eastern Bluebirds lay clutches of three to five eggs and incubate the eggs an average of twelve to fourteen days. Chicks remain in the nest 16 to 22 days. Both adults care for the baby birds in and out of the nest. In Maryland, bluebirds may have as many as three nests each year, caring for a new nest while caring for recently fledged young.
