Talk:Dawn chorus (birds)
From Wikipedia, the free encyclopedia
"Audible radio waves" ???
[edit] Why?
I was hoping to find out why birds sing at dawn.
- I'm still hoping - made the above comment months ago. Why do birds bother? I heard on BBC Radio 4 once that the amount of energy used in singing is proportional to the spare energy the birds have in the morning - so a comparatively mild night would lead to more singing, a cold night less. Do bird brains really sing because they are happy to have survived the night - I dount very much they are capable of emotions like that. I suppose a human analogy would be drivers honking their horns when the dawn comes - why would they want to do that?
- A little Googling produces this link http://www.bl.uk/collections/sound-archive/listentonature/specialinterestlang/langofbirds3.html with another theory of the reason for the dawn chorus. —Preceding unsigned comment added by 80.3.46.91 (talk) 22:59, August 26, 2007 (UTC)
