It's a hard life being a Greenfinch

It's a hard life being a bird at the best of times, without the perils of cats and disease adding to your problems. This afternoon I received a couple of Greenfinch ring recoveries from Norfolk, one of which I'd ringed and one ringed by BTO Research Ecologist Stuart Newson.

'Mine' (if you can ever own a bird) was ringed at Ketteringham, just outside Norwich, in October 2009 and died of Trichomonosis at Halesworth, Suffolk, on 17th September (32km distant). We'll be running a webzine article on the devastating effects of Trichomonosis in the New Year, so keep an eye out for this.

The other bird was ringed by Stuart at Hapton, near Norwich, in December 2009 and was killed by a cat at Ludham, Norfolk, on 30 August (29km distant). This urban form of predation accounts for over 40% of 'known-cause mortality' in Greenfinches.

Who'd be a Greenfinch?!
