Many species of nocturnal birds - owls, night owls, Whip-poor will, etc., which are only active at night, but often can not see.

Most diurnal birds (birds that are active during the day) at night to sleep, but during the migration, some species of flies in the night, when it is cooler. If there is a moon, you can see the geese, in particular, night flight, but when you see the moon is not bright, they're still not there, only. If you live in a quiet night, except during the breeding season, and listen - you can hear the geese and other birds call as they fly.; February 17, 2010 at 8:43 PM

The reasons are is not bird in the night one: it is dark and you can not see, they tend to fly high, so it is less likely to fail or not to fly as a rule very broadly.
In the exposed areas and city centers, the birds are often awake all day. I have often heard the chirping of birds animation two hours in the morning.; February 18, 2010 at 10:43 PM

An owl, but also, at midnight, as you and I see at midday! Most have excellent hearing, too.

The researchers tested the hearing of the owl, the spread a layer of dry leaves on the ground an airplane hangar, is completely closed and dark. Then three mice started in the rack and has launched a new owl into life. Within 5 minutes the owl had caught three mice, only with superior hearing and sight.

Imagine if we could see and hear this right?; February 19, 2010 at 6:53 AM
