I went with a friend yesterday who is volunteering with Audubon SC on a project that is monitoring about a dozen Bluebird nest boxes. This was her first stop, where we saw a Carolina Wren peaking out of the box.
The process is for her to tap the side of the nest box so any adult present flies off, open the box, take a quick photo in the nest with cell phone, then close it back up and retreat. There were five eggs nestled down inside. The boxes get checked once or twice a week until just before the time the chicks are expected to hatch.
A closer look at the nest shows detail of the variety of nest material around what turned out to be five eggs.
Most of the boxes were not in use, but a couple of the others had Bluebird eggs. Bluebirds often have multiple broods so the boxes may already have been used this year and may be again.
I happened upon a pair of White-eyed Vireos today that were working diligently on their nest. It would be fascinating to know how long it took them to get this far. (All About Birds says it takes 3-5 days to complete.)
They brought all sorts of little bits and took turns working them down into the bowl of the nest.
One of them got right down in there, presumably smoothing out the interior.
A lot of the pieces looked like shredded leaf or lichen.
They were flying into the woods and on most trips landed in this nearby tree…
