Needle-tailed Swifts - Finally managed to grab the camera whilst one flock of 30+ birds was passing through.
This one has 'needle tails' - and you can make out the dark feet!
Same bird as above.
A strange looking bird in the photograph. In active moult: old 3 outermost primaries, all other primaries are new. Secondaries; all being replaced. Why the breast pattern? Who knows!
Many of them simply didn't look like Neele-tailed; more like Alpine in shape.
Nice to get a few pics of them.
