House Martin

I have never seen this species, but it keys out easily, even from a photo, with the RES guide: The long and narrow wings are characterisitic of it. According to the guide, it is mainly found on House Martin, but occasionally on Swallow and Sand Martin, too. Also, on House Sparrows, if they take over a House Martin nest.

I have been checking quite a few flat flies, this summer, from small passerines on my ringing site, and they all come out as Ornithomya species, both chloropus and fringillina.

When ringing, they generally fly from the bird, to my head and then into my car, where I can pot them up for later examination! They are very common in late summer.

Thanks for the information Ian - I'm now a little more reassured that my parrot won't get an infestation!
