Please share the pictures this would be an extremely rare occurrence at this time of year.Hi, I can second this. Here in Powys we have currently 2 housemartins roosting under our house in late January. Definitely not wagtails. I’ll take a picture.
... my guess would have been on House Sparrow initially. But then Pied Wagtail. Probably just a couple more Dippers ... ;-)Just need some pics.from the OP to see what they were seeing...
That is a Pied wagtailThey disappeared for a few weeks there over January but are now back patrolling below the house Martin nests. View attachment 1559055View attachment 1559054
