House Martin, Todmorden

 When I was walking back home from the town centre on Friday (16th), I was very surprised to see a House Martin flying over the rooftops on Nutfield Street, which is one of the local terraced streets that usually supports a few nests. Indeed the bird swooped up into the eaves of a house as we were passing. This seems remarkably early - quite often we've been well into May before there seems to be any activity with these nests, even if the odd individual bird has been spotted flying around.
