The Arctic Tern is one amazing bird. They are well known for their exhaustive migrations. These trips are from northern breeding grounds to the Antarctic coast for the summer and then back again six months later. They are rarely seen near land except for breeding. They nest every one to 3 years and lay only 1-2 eggs.
The Arctic Tern chicks are downy when they hatch and start to wander around on the ground and explore within 1-2 days of hatching. I photographed these two chicks on Machias Seal Island. These little fluff balls are probably only 1-3 days old!
