Any Twitchers here
My neighbour and I are trying to identify a strange bird which appeared recently on the banks of a stream .
It is a good swimmer, in flight it resembles a swallow, it is bit smaller than a Blackbird and all black with a white bottom.
We have tried to get close to have a good look but once it spots us the bird flies further up stream so we can't get a good look at it.
I have looked at the RSPB web and the only bird that comes close in description is the Black Tern , any ideas?
Regarding location I live in Worcestershire close to the river Severn and the Slimbridge Wildfowl and Wetland Trust is not far from here.
