1000. Again the nest was unattended as I came to measure the babies,
all 4 of whom are still kicking. Developmentally, their eyes are
still closed, their feet, tarsi, and bills are still pink, their claws are just darkening, and the feather papillae are distinct
rods that have not yet coalesced on their wings, back, shoulders,
and top of head. They still rasp and squeal regularly, and their
egg tooth is still evident.
