鳶。タカ目タカ科トビ属。全長60～65センチ、翼開長150～160センチ。もっとも身近な猛禽類。体色は遠目には褐色だが、白色がまだらに混ざる。嘴まわりは白っぽい。カラスとは、ひとまわり大きいことと体色の違いや飛型で区別できる。ほとんど羽ばたかず、上昇気流を上手につかんで輪を描くように滑空する。愛宕山のような地形は上昇気流が生じやすいため、集まってくる。視力が極めて良く、上空から小動物を狙って捕食するが、動物の死骸や生ゴミなどを漁ることもあり、カラスと競合することが多い。そのためか、カラスに追われたり争ったりする光景がときどき見られる。
Tobi
Black kite. Accipitriformes, Accipitridae, Milvus. The total length is 60 to 65 cm, and the wingspan is 150 to 160 cm. The most familiar bird of prey. The body color is brown in the distance, but white is mixed in a mottled manner. The beak is whitish. It can be distinguished from a crow by its size, its body color, and its flying shape. With almost no flapping, it glide in a circle by grasping the updraft well. Topography such as Mt. Atago is prone to updrafts, so it gathers.
Black-backed Wagtail
White wagtail. Passerine Motacillidae. Inhabited only in Hokkaido in the 1930s. After that, the distribution expanded, and today it is also distributed in Kyushu. It is a bird that adapts to the artificial environment, and even on Mt. Atago, it is often seen on the road that it has a tail that is characteristic of Wagtails.
Is the image on the right a hybrid with the black-backed wagtail? The difference is the presence or absence of hypereyeliner (black streaks in front and behind the eyes), but this individual has no streaks only in the front.
