Caspian Tern - Carr Vale

After the Sabine's Gull was last seen at Carr Vale on Wednesday you might have thought it would have quietened down but news of an adult Caspian Tern there today put the the site firmly back on the UK national rarity map.
According to The Birds of Derbyshire this is just the eighth record for the County. 
It will be interesting to see if it stays. It didn't appear to be having any trouble catching fish, is it a Perch? Once it had eaten it was happy to sit with the Black-headed Gulls at some distance.
