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.|
