There was a massive movement of House Martins through bits of south Devon yesterday. For little more than personal curiosity I wanted to do a bit of analysis on the House Martin passage to see where they came from and where they were going. I would be interested in any HM sightings from yesterday (or the few previous days or today). I can get some of the numbers for the SW from websites but would be interested in any sightings from anywhere from yesterday or the previous few days. More details of what I am looking for are on my blog and you can leave sightings there as comments or here.
Cheers, Rich
