Going to roost.

About 240 Jackdaws flying fast over Salterhebble Hill towards West Vale at 15.45 today.

I am curious where the Black Headed Gulls roost. Copley Water Treatment Works regularly attracts about 200 each winter. They start arriving about 09.30, in dribs and drabs. At about 15.30 they move off, more suddenly than they arrive. They seem to fly up the Calder a short way, then turn left over North Dean Woods, continuing in this direction (south).

Ringstone Edge Res. and Scammonden are in that direction. Can anyone say if there is a B.H.Gull roost on either of these? And if so, what time they arrive in the afternoon. I know, I should get off my backside and go and look for myself, but maybe someone knows already.

At Copley, it's hard to scan all the feeding gulls, but it seems breeding was good this spring. In one group of 20 there were four juveniles. In another count of 60 there were 9 juvs. (Dec. 09 counts.)

The Common Gulls are fascinating on Saville Park. Sometimes they try to bring worms up to the surface by running on the spot. Not at the moment, though - it's a land of giant snowmen.
