It's been a couple weeks since I checked the nest, so I don't know how old the babies are. It looks like there are two. One is in constant motion, stretching, flapping, scratching, wiggling. The other seems pretty listless. They make a funny little yapping sound that I can hear from the top of the cliff. There are two other nests close by, but no other babies that I saw. The Extra is the nest on the opposite cliff; there are two babies there as well.
