Arctic tern chick ringing

14 July 2015

Today, we went to Gerøya. This island has usually many arctic terns nesting. After our trip, we estimated about 150 breeding pairs, spread over the entire island.
Though arctic tern adults have extremely short leggs, their chicks have almost adult size legs on their moment of birth. This means that a chick can be ringed with a metal ring quite early. So we brought our ringing equipment as we do become interested on return rates and survival.
The chicks stumbels over the tundra to avoid predation, until you are close. Than they press down and hold themselves as if dead.
A moment of birth. Janwillem discovers this hatching chick. It is in full action to leave the egg. This few seconds of video captures the moment.
Beautiful chick on the tundra.
