I think the birds involved are linnets, and they follow the starling pattern of flying around, looking to settle in a tree to roost, only to change their mind at the last minute and fly off again. The flock a work that has been doing in at work is only about 25-30 strong, but the flock, or "parcel" apparently, of linnet I observed doing it yesterday numbered around 200 birds.
They don't make a very good photographic subject for a mobile phone camera, you'll have to make do with the sunset over the river for that, but they are a charming watch, tweeping away as they circle around in a skittish fashion.
I was a very tired boy yesterday, and didn't really get a lot of practice in, but today I've had about two hours of walking done. Hopefully as the weather and light improves I will be able to get three hour walks in most days.
