Penguin?

Black-crowned Night Heron is a nocturnal bird.

It is a little difficult to see this species during the day.

But I know a observation spot.

The spot is

the ZOO.

At Ueno zoological park, Tokyo, "wild" Night Herons can be seen in Penguins exhibition.

They are waiting for penguins' food and try to steal.

 In other birds, Black-tailed Gull and Grey Heron (it was not in this day) can be seen.

Of course Penguins can be observed.
