Urban birdsong

I live in a very built up area of East London, and although I am on the outskirts of the borough it isn't very far to the edge of Epping Forest. I have cats, so don't often see birds in my little garden, but there is alway the twittering of the dawn chorus....even as early at 3.30 in the morning...a time when, for some unknown reason I often wake up and can't go back to sleep, so I wander downstairs and sometimes have a cup of tea.

The dawn chorus round here always sounds the same, but this year I've noticed a different little twittering, so I've been on the web to see if I can identify it. I found this great web site from the BBC where you can listen to all our different bird songs. (I can't get a clickable link to show up, but this is the address if you want to copy and paste http://www.bbc.co.uk/radio4/science/birdsong.shtml )

Well I think the only one that sounds remotely like it is the Bullfinch. Not a bird I would associate with east London!

Pretty isn't he!?
