We catch these fledges daily now to take measurements of their wings and body weight. This helps us build a picture of how well they are growing and feeding. We learned of our first fully fledged chick on July 4th, when the warden, after applying a new colour-ring, released the chick and it promptly flew away! Since then, numerous fledges have been observed in the air. The eldest (with the dark crowns) fly with confidence and join the adult flocks. Younger ones remain on the shingle when the adults fly, and still practice small flutters - often crash landing!
The young have also been observed learning to hunt fish just offshore behind the breaking waves. They practice hovering and dropping into a dive towards the surface of the water. They haven't yet progressed to plunging in after a fish, but I have watched them shyly skim their feet with a splash.
When they are not learning how to be a big Little Tern, the fledglings flock together with the adults along the tideline, looking very grown-up indeed. That is, however, until the parents arrive with a freshly caught sprat, and suddenly they are most chick-like again - wings waving, running and stumbling, cheeping as loud as they can to get to the meal before their siblings!
Our highest fledgling count this week has been 139 individuals. We expect that they will begin to move around the east coast a lot more as the gathering for migration looms ever closer. It will be interesting to see where our colour-rings show up!
