Birdsong

This morning on my walk into town I was heartened by a blackbird on top of a tree singing his song. He was about 100yds away and the song was quite loud so I asked myself how many watts of audio was he pumping out ? I haven't got a clue, but perhaps one of our readers has seen some article on the subject ? I was trying to visualise a small loudspeaker on top of the tree at that distance, estimate 5 watts ????? What do you lot think ?

In town = louder, higher frequency and less varied than in country.

Reason - to overcome background noise in town.

You might do better on the Birdforum. 626 thread results with the key word Volume.

Is that because AitchBEE joined or just coincidence? ;-)

You're a wee cheeky devil, bob.

Have to agree it is nice to hear the birds singing, but do wish they would have a long lie some mornings

We have a wren nesting in the clemitas below our bedroom window and there are many a morning when I could so easily pick up a shotgun. For such a tiny bird it sure gives off some volume and is a bit like AitchBee in that is seldom shuts up:-))

The blackbird that does matinee and evening performances at the back of my flat is a most welcome 'busker'.

Surely the birdsong should be measured in dbA/Metre?
