Bath's 2009 chick colour-ringed

In late March 2009, the pair of peregrines in Bath laid 4 eggs. Two hatched at the end of April and one survived. Recently, myself and Adrian George, British Trust for Ornithology, colour-ringed the remaining young chick.

The ringing was filmed by the BBC and featured on BBC Points West, the local news for the West of England. http://news.bbc.co.uk/local/bristol/hi/people_and_places/nature/newsid_8063000/8063538.stm

The young bird was a female. Despite being just under three weeks old she was a big bird - without any siblings she has had all the food brought in by her parents to herself. She was given a unique metal ring on her right leg and a blue colour ring with black letters AP on her right leg.

The chick's dad is actually the bird's half brother. The dad is an individual we colour-ringed as a baby in 2007 at the same nest site. His ring combination is AA. After the disappearance of his dad in 2008 we he appears to have paired up with his mum, the breeding female. This inbreeding is not unusual in the bird world and shouldn't be detrimental to the health of the chick.
