Duelling Chaffinch

I have been trying to capture a chaffinch in my garden that sings at the top its voice all day long. I don't know how it manages to feed. Haven't got a decent shot of it. :(

I visited Fishers Green and this one was full of testosterone and so caught up with duelling in song with a rival that it didn't seem to notice me.

I have read that in Belgium there is an ancient traditional sport called vinkenzetting which pits male chaffinches against one another in a contest for the most bird calls in an hour. I thought about counting how many times my garden bird sings in an hour. Bet it would win a comp. :)
