Birds - Great Tit

Great Tit calling. Perched on a London Plane. Herne Hill

I thought I would blog my first bird and the Great Tit was the first one I saw as I left my flat this morning. I was alerted as they have distinctive loud calls that to me sound a bit like the famous soundtrack; Norman Bates Killing in Psycho (That may just be my odd description). Great Tits are famed for having a large variety of calls around 50, so don't be too surprised if you don't experience my Hitchcock reference.  A lot of their calls, you can listen to by clicking on the RSPB link to the left of this page.
         Great Tits are the hard men of the Tit family, they can be very aggressive and territorial especially when feeding. They have occasionally been known to kill other birds. One was recorded killing a goldcrest and carrying it off in its feet like a hawk. This is unusual behavior, they do not normally commit extreme violence. The nest in holes often unusual ones like letter boxes or drain pipes. They predominantly feed on insects, fruits and nuts Females may lay between 5-12 eggs.
