One for the anoraks!

Well I did promise some 'tristis' recordings, and after a good bit of head scratching, and some consulting with the 'guru' of all such things Magnus Robb (cheers once again!), I can give you the following...

Siberian Chiffchaff ('tristis')

The reason for the 'head scratching' was the variety of calls this bird was giving. The typical 'tristis' call is described in 'Collins' as a "piping, straight (or negligibly downslurred) 'hii(e)p'... ". This call was given by this bird, but it also varied the call with some deviations, including a slight upward inflection in the middle of some calls! And quite a few calls with the downslurred ending mentioned in the 'Collins' guide. I know these birds are still a bit of a 'work in progress', and I wanted to make sure I wasn't missing out on any new info. As I believe the 'tristis' bird to be a first winter bird, I've included the calls of a young 'collybita' bird raised in Shetland this year as a comparison. As you can hear they do sound very different, with the local bird, the calls all have a smooth upward inflection as expected...

Common Chiffchaff ('collybita')

Redpoll overdose!

Back on Unst today, but this time to try for better recordings of these 'Sibe' Chiffchaffs! but more on that later.

Good birds today included; 1 Arctic Redpoll, many (60+) Lapland Buntings, 2+ Sibe Chiffchaff, 10 Snow Buntings, 1 Lesser Redpoll (a good bird up here!), many Mealy Repolls and a few NW Redpolls too. It seemed like everywhere I went I could hear flyover Lap Bunts and Redpolls, and god alone knows how many of each were on Unst today!

'Tristis'

I decided to try the top of Unst this morning, and by 'the top', I mean Hermaness Nature Reserve! certainly not for the feint hearted in this weather either. The rain was constant, and the visibility in the fog was negligible... It was a bloody hard job to find my way back to the car, never mind any wayward 'yank' Pipits or Waders!!!

After the soaking I received, my enthusiasm was a wee bit dampend, but I still decided to try working a few areas before heading home. Best I managed was Arctic Redpoll (BT's bird in Baltasound), 3 Sibe Chiffchaffs, 4 Lapland Buntings, 1 Merlin, lots of Mealy Redpolls and a couple of North-western Redpolls and strangest of all.... A Dunnock on Hermaness NR!

Sibe Chiff;

And of course a sonogram of the distinctive call. For anyone interested in calls... (The actual recording is a bit 'pants', so I've just included the sonogram instead)
