A flock of House Swift was seen at Long Valley this afternoon (2010.01.09). There was at least 60 - 70.

However, I found there were swifts with white underwing. One of them was captured below.

Also a House Swift or other species?

Thank you for assistance in identification.

This is a House Swift - you can see the pale rump on this clear photo.

I agree this is a house swift. The underwing looks paler because of the angle of the bird, so that the wing is catching the sunlight

Thanks both kmike and ajohn for the identification and explanation.
