Willow Warbler ssp?

This bird was ringed last April in the Balearics. I have a couple of questions for the Willow W. experts out there, Can this be a very pale ssp acredula? Or is it too pale even for acredula?
Thanks in advance

I'd say it was a northern acredula or even a yakutensis but I'm afraid there is no real way to be sure. Its all probabilities!

Yes, it´s really bad with this bird. At first I thought "if this guy isn´t a yakutensis...", but I guess it´s too white even for that! Check the wing bend, there´s no yellow at all! We trapped pale acredula looking birds like these new pictures of another Willow W., very pale birds but some yellow on them, but the thread bird looks as if yellow colour is suppressed on it. Green is visible on its rump though, even more than on the bird in the new pics. I have no yakutensis experience at all, just what I´ve read, maybe someone in this great forum has and can help a bit.
Thank you guys

Yepp. Living in acredula country, I'd probably react to seeing a willow as pale as that one...

Hi,

I took some photos of both acredula and yakutensis in the gulf this spring. IMHO your bird is not yakutensis (which is bright and often streaked slightly), and is more like acredula.

If you're interested the photos are at http://www.charliesbirdblog.com/~cha...XB10may05.html

Cheers

Hi all, a few answers:
ESTEBANNIC
The bird was trapped in Sa Dragonera Island on April 26th 2005, very close to where you live (I think).
Net-falco
Its legs where a bit dark for a classic Willow but not too much, paler than what your bird shows. Apart from that both birds look similar. Do you know if yours showed the same green rump?
Here are some more pictures of same bird, now under strong sunlight.

Isn't the wing wrong for trochilus?

You´re right!, it doesn´t look like a yakutensis. I have to say I expected it, the yakutensis descriptions I´ve read mention the greyish breast and describe a drab but more colorful bird than the thread one. I guess a very few ssp acredula or maybe even ssp trochilus suppress all yellow tones and become these striking drab birds. Thanks a lot everyone for your help

Yes, the finnish bird appears a bit short on the primaries side but I guess the ringers checked it carefully, and the face shouts trochilus imo

All measurements was suitable to p.lus.However, this mystery looked bit "stronger" like p.lus (head and legs).And there wasn´t any green or yellow color.Here is couple other shots.First one has bad light,so the color isn´t so grey as it should be,and second picture with p.lus...Strange bird,like yours too Motmot.
