The last download of footage showed the chicks on Nest 3 are doing well with fish being consumed in quite a few of the short periods of daily recording.
Chick 2 was about 9 days old in the image below; the sibling is a few days older and had the dark second down.
In the early evening the chicks had fed when recording started. The male landed to take his meal away although often he dines with the family.
The next evening the chicks hadn’t finished eating when the recording began. You can see both have the dark down.
