A Letter From India

Prasad Ganpule

Hello Martin I read with great interest the various articles on grey shrikes on Birding Frontiers. They are very informative. I saw a shrike in February in Desert National Park, Rajasthan, India which we could not identify with certainty. I am attaching some images of this here. The white in wings is too much for lahtora or pallidirostris , the only two grey shrikes occurring in India. Could it be any form of Great Grey Shrike or something else ? Your help is very much appreciated. Thanking you, Prasad Ganpule

Prasad, clearly a sharp observer of birds,  previously wrote about taimyrensis like large white-headed gulls, with accompanying superb photos. We previously published these two photos here and there is a much fuller Birding Frontiers post on Desert and Asian Grey Shrikes. Picture-16-2-2014 169Picture-16-2-2014 182 Below more photos of the same bird. The bird is an adult and the general plumage pattern is like Asian Grey Shrike lahtora as might be expected from the location. However it definitely looks rather more pallid grey above than the darker grey of typically described for lahtora and the length of white at the base of the primaries and perhaps also the amount of white in the secondaries is even more than normally described for lahtora. Variation in lahtora or another explanation? Don’t forget there is the strange case of the lahtora Asian Grey Shrike in Norfolk, England (scroll down to end). Check out the expected pattern of white for lahtora via links below From Prasad:

Mystery Grey Shrike

to be continued…

Here’s a couple of photos of a ‘Great/ Southern/Desert’ etc etc Grey Shrike photographed in February this year.

These are fascinating and quite beautiful birds. Certain individuals don’t always fit described forms, and the whole group has taxonomic uncertainty written over it all it. Surely these Grey Shrikes are a frontier?

For now please have a look and if you think you know what it is, that is what form or taxa it might be- please say. No I’m not saying where it was photographed :)

Desert and Asian Grey Shrikes

Explorations

Martin Garner

Shrikes, aka butcher birds are always pleasing to see. Recent molecular studies have forced (yet another) rethink about what used to be called ‘Great Grey Shrikes’ and how they might be related to one another. A division between ‘Northern’ and ‘Southern’ forms is already well-known. Here’s a look at the Southern Grey Shrikes where there is much more to discovered about identification, genetics, vocalisations and interbreeding of forms. A birding frontier! Furthermore an ‘Asian Grey Shrike’ in Norfolk in 1982 considered to be an escape might be worth revisiting.

A paper published in 2010 (see end) suggested different possible (new) taxonomic treatments, with an option being to treat the southern birds as 3 separate species. This position has been adopted by e.g. Dutch Birding:

Desert Grey Shrike Lanius elegans with taxa: elegans, koenigi and algeriensis

Iberian Grey Shrike Lanius meridionalis

Asian Grey Shrike Lanius lahtora with taxa: lahtora, pallidirostris and aucheri

What’s confusing is that birds with the most similar plumages and in some case breeding closest to one another, are not necessarily the most closely related. So takes some getting your head around! Expressed simply a broad sweep from the Canaries to India reveals most of the southern taxa are dark smoky-grey looking shrikes. From koenigi in the Canaries, algeriensis of coastal North Africa, aucheri of the Middle East through to lahtora in India all look broadly very similar. Into that mix the Iberian meridionalis is similarly dark, often with pinkish caste to underparts. The outstandingly paler form is elegans spanning right across inland North Africa through to the Middle East while the different looking pallidirostris sits perched in the NE corner (Central Asia) of this range.

Southern Grey Shrike 'koenigi',  Lanzarote, Sept 2013. This insular form is resident on the Canary Islands and is a dark grey above merging deep extensive grey tones below, contrasting with white throat. Limited white in wing and large black mask with hardly any/ no white supercilium. Dutch have it as 'Desert Grey Shrike' and a subspecies of elegans (with algeriensis as another ssp.). The Iberian form meridonialis is viewed as a separate species 'Iberian Grey Shrike' by both Dutch Birding and the 2nd ed. Collins Guide.

Southern Grey Shrike, , Beit She'an Valley,  Israel Nov 2013. In interesting bird, Extensive black mask but wasn't especially darker above and  with more white in wing than other easy 'aucheri'. This bird could be what is assumed to be an intergrade form between darker northern aucheri and paler southern elegans.

Adult Asian Grey Shrike, Roger Tidman. A remarkable record from Norfolk! Found at Toftwood, (nr. Dereham) from August 23rd 1982 it was later found dead there ‘at the end of the year’. The specimen was apparently identified by the BTO and Tring as ‘of the Indian race’ lahtora. It was considered an escape at the time due to its tameness and residence in a built-up area. Characters pointing to lahtora include extensive black mask, darker grey upperparts but whiter underparts and more white in wing than e.g. aucheri. Intriguingly it's appearance is not much different to the bird above photographed in Beit She'an Valley, Israel. This bird seems worthy of further investigation. It seems an unlikely vagrant whether aucheri or lahtora, though stranger things have happened. How many 'Asian Grey Shrikes' were kept in captivity in Western Europe in the early 1980's? Isotope analysis of feathers from the specimen could be revealing. This photo © Roger Tidman not be reproduced in any form.

Daurian Shrike at Flamborough

and Identification of First Winters

by Martin G.

It’s a privilege to live at Flamborough near some very keen and capable birders. I was reminded of this last Tuesday morning. I arrived back from Shetland on the Monday evening (14th) and by tuesday lunchtime had seen Dusky Warbler, Red-breasted Flycatcher, Yellow-browed Warbler and this. An ‘Isabelline Shrike’ Found by Phil C. earlier in the am and only seen briefly it finally gave itself up ear he cliff top. So which type/taxa/species :) is it?

2 types are recognised as having occurred in Western Europe. The Daurian Shrike ‘isabellinus’ and the Turkestan Shrike ‘phoenicuroides’.

All photos of Flamborough bird by Martin Garner, 15th October 2013

Daurian Shrike 1cy m Flamborough 15.10.13

In a nutshell: this is a first winter bird. My gut reaction on seeing it was that it looked like a Daurian, albeit a darker example. Daurian is seemingly occurring much more regularly in Britain in recent years than Turkestan.  Like Siberian Chiffchaffs and Pallid Swifts (and a host of others) seeing these shrikes in the right light conditions/ accurate photos is absolutely critical (and often not easy)

Key features on the Flamborough bird:

  • Overall gingery wash to the brownish upperparts
  • Gingery orange colouring prominent on the flanks but extending from rear flanks all way up to below ear coverts (hard to see latter).  Centre of throat and central breast/ belly white.
  • Tertials darker brown but not strong contrast with uppers. Mask slightly darker brown with gingery wash at some angles- not blackish brown
  • Rump brighter orange with only very weak dark marks on some feathers tips
  • Orange centred median coverts

First winter Turkestan should have cold earth brown/ grey brown uppers with darker (almost blackish) mask and flight feathers. Uppers contrasting strongly with mostly clean white underparts (marked with blacker bars/chevrons). More often retained juvenile feathers in rump and mantle/ scaps with white or black centres to median coverts (not orange!).

Here’s the Flamborough bird:

Daurian Shrike 1cy b Flamborough 15.10.13

Daurian Shrike 1cy k Flamborough 15.10.13

At close range and in flat light and lovely gingery tone warmed the upperparts. The ‘mask’ could vary from darker to paler depending on angle with, again a gingery tone washed through.

Daurian Shrike 1cy h Flamborough 15.10.13

Daurian Shrike 1cy g Flamborough 15.10.13

The flight feathers, especially tertials were not especially dark (sooty/blackish) and contrasty

Daurian Shrike 1cy f Flamborough 15.10.13Orange/ gingery wash went from rear flanks to the pale area below mask (lower ear coverts). Underpart barring/chevrons more brown than black.

Daurian Shrike 1cy o Flamborough 15.10.13Like my favourite chocolates, the median coverts were orange centred (black or white centred in Turkestan). The small upper tertials and greater wing coverts almost had a subterminal orange band.

What about intergrades?

This question was posed by some. This study by EN Panov (2009) demonstrated spatial isolation between phoenicuroides and isabellinus (speculigerus in Panov) in a potential contact zone. Furthermore a time difference in arrival of 2 months on breeding grounds between the 2 taxa was noted. Panov’s conclusion is that, while there are occasional examples of interbreeding the evidence presented suggests the 2 should be treated as independent species. One of the consequences for observers in Western Europe is that intergrades are arguable likely to be rarer than ‘pure’ birds. Perhaps we should approach identifying firsts winters (and the somewhat easier adults) with renewed confidence.

Variation not Intergrades. Seems to me learning about variation in young Daurian and Turkestan Shrikes (think of the variables of red/grey/brown seen in Red-backed Shrikes) is the key. Here’s a plainer first winter Daurian Shrike from this last week in Lincolnshire, still showing the same ‘themes’ as the Flamborough bird.
