It takes some skill to determine if a nest has hatched. Is that a feeding you saw or just preening? Is the female really sitting higher? Did the male come in and look at a new eyass or was it something else that caught his eye? Did you see a slice come from the nest?
At the Fifth Avenue nest there are signs that the hatching process has started. I didn't see a feeding or a slice but I did see the female sit higher in the nest and spend a great deal of time off the nest bowl.
I included lots of footage in today's video for those who want to form their own opinions.
