Common House Martin (?) at Tai Sang Wai today
9th Dec 2012
ID Mk IV + 800mm lens.
Four poor "record" shots of what may be a Common House Martin.
There seemed to be only one "House Martin" around, so hard to give size comparison.
The bird in photo 1 is the same bird as in as 2,3, & 4 I think.
The amount of white on the rump (2,3) attracted my attention.
There seems little darkness on the flanks, (note shadow of wing in pic 4) I fancy that the white underside goes right up to the chin.
(I have noted the contents of Paul Leader's paper on p. 263 of the 2009-10 report, and offer these record shots for comments/discussion by anyone !)
Pic 5 is a "re-post" of an Asian House Martin I posted here last year
