calls

Chiffchaff call sounds like a squeaky toy at times and is usually monosyllabic tseep. It can sometimes be comprised of two sylables, but the first is always very short t-seep whilst the Willow Warbler's call is composed of two syllables of roughly eaqual length tu-ee tu-ee, it is a low sound in the middle and ends on a high note.

From your description of the call Chiffchaff sounds more likely. It is nigh on imposible to tell them apart visually in the field. Even in the hand it is tricky!

This individual looks very "downy" so could have been a youngster from this summer.

Sorry about photo quality!

Sorry about photo quality! Camera on maximum zoom and subject high up in tree! Thanks both of you for your input.

Don't worry we all have to

Don't worry we all have to start somewhere. Birds are notoriously difficult to photograph. Especially when they are flitting around in the trees.

Do you know which of my call descriptions it fitted best?

Ophrys, you can't tell them

Ophrys, you can't tell them apart from leg colour alone. I helped ring a Willow warbler a couple of weeks ago that had very dark legs. The most reliabe way is to spread out the wing of the bird and check the outer primaries for emargination. I forget how it goes now but one of them has 1 more emarginated primary than the other.

There are certain field characteristics (http://www.flickr.com/groups/wilduk/discuss/72157623871990349/) that will help if the bird isn't singing, but there is a great deal of overlap so some you would be able to pin down in the field and others wiould have to be left as willow/chiff

John.

Thanks

I ringed half a dozen of each this morning. Chiffchaff is emarginated to P6, Willow to P5.

I would say monosyllabic

I would say monosyllabic tseep is the better description...

Chiffchaff

Then it is most likely a chiffchaff with pale legs :) I'll let you do the honours of adding an ID Jon.

Willowchiffs

Welcome to the world of Willowchiffs on iSpot! There will be an increasing number of blurred photos of distant warblers, over the next few weeks! Inevitably, the primary projection is nearly always obscured by a leaf...

I think we can only judge them on what is visible, really, as calls can be difficult to describe...a hweet can be hard to tell from a hu-itt, unless you are used to listening to them both (and of course, they vary).

Enjoy!

PS: I am not doubting Jonmortin's monosyllabic tseep!

OK but Ophrys's 4 star

OK but Ophrys's 4 star reputation will hold sway unless there are further developments in the debate!

True, but hopefully other

True, but hopefully other people will add to this during daylight hours ;)

One day I'll get around to adding all of my bird photos and I'll hopefully come close to 4 stars/birds!
