下記はウイキペディアの一部 英文を日本文に日本文を英文にしました。サシバはアジアの猛禽類の一種で、繁殖は東ロシア、北中国、韓国、日本と冬の東南アジアで行います。日本の繁殖地には3月下旬から4月上旬にかけて 雄は先に到着し、雌が到着するのを待っている間、自分たちのナワバリを守っていると考えられます。雌が到着した後、巣作りと交尾が始まります。
主にヘビ、トカゲ、カエルといった小動物、セミ、バッタなどの昆虫類を食べる。稀にネズミや小型の鳥等も捕らえて食べる。人里近くに現れ水田などで狩りをします。（ウイキペディアの英文と日本文から）（私は野鳥の専門家でも学者でもないので、雄が雌よりも先に到着すると言うことを初めて知りました。そんな訳でいつもこの分野の知識はウイキペディアと専門書から得てます。）

Below is a translation of Wikipedia's English sentence partly into Japanese sentence and Japanese sentence in English.

The grey-faced buzzard (Butastur indicus) is an Asian bird of prey.

It breeds in East Russia, North China, Korea, and Japan, and winters in South-east Asia.

Grey-faced buzzards arrive in the breeding grounds of Japan from late March to early April. It is assumed that males arrive in the breeding grounds and wait for the female to arrive, while defending their territory. After the female arrives then, nest building and copulation begin. 

They mainly eat small animals such as snakes, lizards and frogs, insects such as cicadas and grasshoppers. Rarely catches rats and small birds and eats them. It appears near the river and hunts in paddy field etc.　(quote from Wikipedia in English and Japanese) 

（Because I am neither a wild bird expert nor a scholar, I have learned for the first time that male arrived earlier than female. That's why I  usually get these knowledge from Wikipedia and specialty books in this field.）

 The background is cherry blossoms.
