The evening chirping signals the rest of the flock to come home before it’s time to
be quiet and rest through the night. The birds
You may have noticed a cacophony of birdsong in the wee hours of the morning. Scientists call this the dawn chorus. It can start as early as 4:00 a.m. and last several hours.
In the early morning, light levels are too dim for birds to do much foraging. Since light levels don't affect social interactions as much, it's a great opportunity to sing, instead.
The songs of birds are learned, not inherited, much as with
humans.
Usually a male that is defending a territory or attracting a
mate will sing from one of the highest or most conspicuous spots available.
Birds usually do not sing around their nests. a few may sing
a quiet "whisper song" that can be heard for only a few yards.
A bird may sing a song because it is well fed, stress free
and happy.
