Out of county gulling

On Monday I had a cracking afternoons gulling in Cambs.  I started off at the tip at Milton and spent two happy hours pouring through the few thousand gulls coming and going.  Top of the pops were up to six Caspian Gulls, with a back up of around ten Yellow-legged Gulls.  I was disappointed not to bag myself a white-winger as up to two juv Glaucs had been seen the previous few days.  At around 3:15 I thought I should give the Grafham roost a go.  I was pushing it get there before it got too dark, but managed to pull up just after 4pm

I started scanning from the fishing lodge and within five minutes I had found a lovely looking adult Glauc not far off shore.  All other hopes of finding more Caspo's drifted in to the darkness as I happily watched my first adult Glauc of a good few years.

The videos above were digiscoped (at great distance!) with a Swarovski ATS 80 HD, 25-50x zoom, and Nikon V1 and kit lens.

Another Sibe Chiff

At the same time I found the 'other' Siberian Chiffchaff at Marston Sewage Works I also came across this bird.  It is distinctly different - its more beige and buff in colouration, without the greyness of the other bird.  The wings and tail, although tinged green, aren't nearly as bright as the other bird, and it also has a light wingbar.  This bird is also much more confiding and spends more time in low vegetation.  It has also been silent on every visit - or at least I haven't seen it call, or been close enough when it has.

On close inspection there is some yellow in its plumage - however this is only visible in the images above.  None of this yellow was visible in the field.

More shots of this bird by Neil Wright can be found on the BedsBirds blog here.

So, should both birds be labelled 'tristis'?  One bird looks good but hasn't called, and the other bird looks good (but more contrasting) and has a slightly strange call. Hmmmm.

Wonderful little birds - Dartford Warblers.  Even better when you can see them just a few miles away from home.

That Chiffchaff again

I bumped in to that Sibe Chiff again today - it really is a looker.  Still doesn't sound quite right though...

There are more shots of this bird by Mike Lawrence on the BedsBirds blog here.

Iffy Chiffy

Looks ok for tristis, doesn't it.  Its a nice shade of grey-brown, with green restricted to the wings and tail.  That's all well and good, but now listen to it...



It's not the 'classic' tristis peep.  It sounds a lot more like a collybita.  I wonder, what do grey abietinus sound like?  Do they exist?  And if they do exist, would they look and sound like this?

There is currently an interesting discussion on the Surfbirds forum of a similar bird from Sweden.  The video shows a grey tristis type chiffchaff calling like a collybita.  The thread can be found here.
