I thought about that shortly after I posted, and specifically when what it is presumably a bird in juvenile plumage was posted elsewhere (in fact by Owen in the photo  gallery).   I'd be interested to read your opinion on the age (and identity) of that bird (though if it's not a juvenile Brown Shrike  I'm seriously confused).   Mike Logged Paul Leader BBS Member BBS Senior Member     Posts: 83 Re: Unsure Shrike on Lamma « Reply #4 on: Sep 25th, 2006, 11:26am » Quote Modify I agree, that bird is a juvenile.  In fact, if it was photgraphed by the school, I had good but brief views yesterday, which I suspected (as is, I think, confirmed by the photos) was a juvenile cristatus Brown Shrike (due to rich brown colour to the upperparts).   Anyhow, it has moulted none of the juvenile plumage, compare for example the retained juvenile upperparts, median coverts, primary coverts etc. with the Lamma bird.   Note also the difference in the ground colour of the Lamma bird (a first winter lucionensis) and the Po Toi bird (nominate cristatus).
