Tino Mischler has been checking through the stamps on my pages for Song Thrush (Turdus philomelos) and Mistle Thrush (Turdus viscivorus) and has made some observations about anomalies.
The stamp from Turkish Cyprus which is supposed to show T. philomelos actually has a bird that is right for T. viscivorus (Greyish colour and cheek markings).
Conversely, the stamp from Bahrain listed as T. viscivorus shows a bird that looks more like T. philomelos: brown back, no vertical eye-stripes.
I shall change these two identities in my next update.
The best example of T. viscivorus would appear to be the stamp issued by Bulgaria in 1999.
