Firstly the group has increased in size to up to ten birds at a time. I haven’t seen that number of birds together in one go other than during the winter, and then in mixed flocks of finches. On recent occasions the Yellowhammers seem to have been in the company of Goldfinches and Chaffinches, so perhaps the congregation is a run-over from winter into spring?
So if there is a second group the next question concerns the total number of birds in the area. In my wanderings around the pathways and lanes around the village I have noticed numerous Yellowhammers atop the hedges singing to establish territories, but I have not noticed any groups of birds – indeed I can’t see those birds leaving territories to join a group to feed in my garden! So with the two groups there are nearly 20 birds above what I suspect is the resident population, and I suspect that I have witnessed a migration. Perhaps these birds came south when the weather turned snowy and cold in January, and they are only now moving back. I think I will have to do some research with the BTO.
Oh, I almost forgot, we also had a nice looking Stock Dove come for a feed.
