エリグロアジサシのコロニー

エリグロアジサシのコロニーを2カ所見てきました。まだ、抱卵中のペアや孵化後3週間以上たったヒナなど十数ペアが繁殖しています。海岸から営巣する小島まで30メートルほどしか離れていないので肉眼でもヒナが見えるほどです。

今年は台風がまだ来ていないので多くのヒナが巣立っていきそうです。^^

Black-naped Tern

This pair had not yet started incubating.

Since incubation was still going on as well, this chick is probably about 2 days after hatching.

Black-naped Tern

This chick, visible only from the face, has grown considerably. Black-naped Terns fledge about 28 days after hatching, so this one is already more than 3 weeks old.

I tried photographing only the flagged Black-naped Terns.
