Dusky Warbler and curious Goldcrest

Monday 5th October

I went a little slower and enjoyed Virkie’s shoreline. Yoav joined Pierre A-C to explore Walsay and I expect ended up talking forever about Siberian Thrushes! The ‘south ness’ had an increase in Barnacle Geese over and landing in good numbers as well as the more usual Pink-feet. Wild Geese. There is a magic about them.

Paul and Roger, together with Peter Colston and Tony Quinn went to Sumburgh and scored a Dusky Warbler at Grutness. RR aced a lovely photo showcasing superbly key Dusky Warbler features:

Goldcrests from further EAST

Rather predictably Goldcrests and  Robins became a little more evident today (often goes with Dusky Warbler finds). I was nevertheless taken aback when near octogenarian Peter Colston (Mr Tring Museum for a VERY long time) began ruminating on ‘eastern Goldcrest’. WHAT!

We were birding together at Geosetter and watching and photographing several Goldcrest (plus Yellow-broweds and a curious ‘grey’ 1cy Pied Flycatcher).

coatsi Goldrest!

He was drawn to this Goldcrest by the ‘extra grey’ extending from the nape onto the mantle. Maybe it’s no big deal. Maybe it’s even the ‘angle of the dangle’. Can you see how there is more extensive grey, contrasting with olive green- but in the mid-mantle region rather than at the base of the nape. Often specifically British Goldcrest show almost no real contrast between grey- olive head and olive mantle. Nominate/ continental birds range from obvious contrasting grey heads to some more like British birds. See Yoav’s blog from yesterday for examples)

I have long been interested in greyer heads/ identifiable ‘Continental Goldcrest’ (see me illustrations in last month’s Birdwatch magazine). I never knew about birds from further east… other taxa…but then this is Peter Colston I got to go birding with! I checked out Goldcrests from further east and discovered a taxon- ‘coatsi’ Goldcrest. The range is east of nominate regulus. This is how they are described on the Birds of Kazakhstan website:

“Mantle is lighter, grey on rear-neck more developed than in regulus.”  Birds of Kazakhstan

Now this is only a little exploration. We may never get ‘coatsi’/ birds from that range in W. Europe but its fun to explore and learn. And we were also watching a Yellow-browed W as Peter pointed out. So here’s the bird. It’s how I explore and learn 🙂

I finished my day with a stunning (rarely are they not) OBP at Scatness. Not easy to see. Not everyone getting on to it. I was indeed fortunate to be wowed by the head and underparts and it meander through rank grass.

    Hey martin, You know we aren’t into birding in the same way all you guys are but really enjoying your blog on Shetland. Glad it is going well. Mum and Dad H.
