A couple of Goldcrests called from some willows adjacent to the reedbed and a female Sparrowhawk coasted across the pool. Another raptor made an appearance in the form of a Buzzard mobbed by Corvids heading towards the river.
Before the Pied Wags came in to roost we ringed a few Greenfinches that were on their way to roost in the water treatment works, and at least 30 or so showed some interest in the MP3 player. It was difficult to estimate the numbers of Wagtails roosting, but there must have been at least 180.
We ringed 29 birds as follows:
Greenfinch - 6
Pied Wagtail - 23
I'm not sure what to do in the morning as it is forecast for a brisk northwesterly. I'll see how many Orkney brewery beers I sample this evening and then make a decision!
