red bcked Shrike with warm colors (1 Viewer)

[Michał Jaro]

I wonder about this bird, like a red-backed shrike, but undertail coverts in warm colors, side - something like buff and in front of eye the same worm colour.
Is it still red-backed ? I don't think it was a sun effect - the throat and underside n the lower part are still whitish. Please help

Looks like a R.B. Shrike to me, where and when were the images taken?

Poland, september. Yes I agree but I've read about red backed ("Identification of red-backed,isabelline and brown shrikes") that female and imm.:
"The undertail is always greyish" ??
