オサンポ walk - 鳥bird: 渡り鳥グループ？ a group of a migratory bird?

暖かき

空に集まる

渡り鳥

It’s a warm day

In the sky, there is 

A group of a migratory bird

渡り鳥さんのグループじゃないか、と思うのですが。いかんせん電線の上は遠すぎます。こういうときはレンズが長く重くても、望遠が欲しくなります。

嘴がするどく長めで、顔が黒くて白いほっぺのワンポイントがあるように見えます。君たちの名は…。

I guess that they might be migrant. They were on the electric wire, it’s far away from me. I wish I would have got a telephotograph at that time, even though it’s heavy and long. 

About the birds, they seem to have got a sharp beak, black head and white spots on their cheeks. Who might have this appearance?
