今朝、このニュースを見て dumbfounded な出来事を思い出しました。
早朝、愛犬を散歩させているときに
今朝はやけにカラスが多いなぁ～と視線を前に向けると
歩道のベンチに座ったオジサンがカラスに餌をあげているではありませんか！！
ビックリを通り越して無意識のうちに愛犬を連れて来た道を戻りました。
I was dumbfounded when I saw an older man feeding crows in the early morning.
They were gathering from all over the place to get the food.
I think he's trying to tame them.
My friend told me that crows can remeber human faces,
so if you feed them,
they recognize that you help them and they become a littel more friendly.
I heard that crows are smart enough to do some puzzles,
but I don't know they could recognize human faces.
