Swift. white-rumped

Unread postby Johan van Rensburg » Sat Jan 19, 2008 5:20 pm

Swift, White-rumped; Apus caffer

This swift flew into our house and got entangled in a curtain, giving a rare opportunity to take close-ups of a bird nornmally only seen in flight!

A handsome bird - note the white chin and throat

These graceful flyers are gragerious birds that migrate in flocks up to 100 strong. They roost in or nearby their nests from shortly after sunset to just before sunrise as well as during the day when it is windy. The swifts drink on the wing by skimming the surface of water.

The bird's grip was surprisingly powerful for such small feet!

Those aerials are very difficult for me so yesterday I managed to catch one in flight with the 500m lens on auto.....

I really hoped that if I could capture one in flight that I would be able to ident on my own.... :doh:

@Cherries: A small, bulky swift with a white throat and a deeply forked tail should be a White-rumped Swift, I think.

I would go for Black,

If it was White rumped you would see atleast a little bit of white on the rump. Black Swift also has the light Primaries and forked tail.

Got myself in a little bit of a self doubting hole.....

I was certain of my I.D in the field but now when looking at the photo's the "shallow" fork now looks rather deep!
I thaught I had a horous swift1 Now I'm not so sure anymore.... could be a white rumped swift? Would you guys be so good and confirm this one for me!

Thanks :slap:

Its a pity one can not see the rump of the swift,but the fork in the tail is deep enough for a white rumped Swift, The rump of the WRS is a narrow curved white area on the rump
