Is the Isabelline Shrike on Brendan's ringing page really a juvenile
(1st cal. year bird), or maybe it's rather a 2 cal. year (spring) bird (or older in autumn)?
Howard passed your query re the isabelline shrike photograph to me. You wrote

The bird was caught on the 18th March this year, presumably on migration north from its wintering quarters. I attach the photo of the extended wing for you here.
The bird is of the subspecies phoenicuroides (Lars Svenson 1992ed) which occurs in E and S Iran and Central Asia and further afield. Svenson states that some young retain a few juvenile Wing Feathers (often inner 2-5 PP) into 2Y spring.
From the attached photo you can see P8,9,and 10 in addition to SS1 and 2 are old. Some of the PCs are also old. (In fact my notes state PP9 and 10 and SS 123 though the photo suggests differently!!)
I code this as a 5 i.e. definitely born last year. Hence the ‘Juvenile’ label on the website.
Moult patterns are very interesting here in Bahrain. Birds often come through in early spring still in moult. I would never see this in northern Europe!
Hope this helps and thanks for the interest.
It is always interesting when you have two photographers in tow to see how they view the same species The following images were taken by Juhani Kyyrö - to check out AJ's images for these same individuals click here

Mark Beaman - having missed the morning boat to Hawar and with time to kill waiting on the afternoon sailing at the "Ad Dur" Hawar ferry terminal observed a Sooty Gull Larus hemprichii circling the small harbour.
This is the forth accepted record of this species for Bahrain, previous records are 2 obs for Manama in August 1969, M Gallager. 1 Sitra March 1988, M Hill.
On the previous day Mark and his partner Hilary observed several Bimaculated Lark Melanocoryphya bimaculata at two locations Maharraq (Busaitain) and Badaan Farm. An under observed species not recored here since 1997.
