For a couple of days, when we went looking, we only found Beatrix on the Diner. But yesterday, was a successful day.
We found three of the chicks sitting together, pretty as you please. They were Bristol (red tape, on left), Belle (yellow tape, in middle), and one of the male chicks (not sure which one, the tape was just "dark"), when a helicopter came by. So... four birds in the picture.
A short while later Bristol was chased off her perch when Belle launcher herself in Bristol's direction. Both birds circled, then took off and we lost sight of them. The male seemed to be happy being left alone.
Bristol... Belle...
