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 ?
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:-))
