Last few days, here has been posted a set of beautiful parrot stamps from Philippine, and also three tern stamps. The last tern stamp shown as above maxicard, however it seems oddly as two terns are in different looks : the feathers of Philippines one is in black colour while the card photographed as grey. No surprisingly they are two sub-species, the photograph of the card is Sterna hirundo hirundo while stamp is S. h. longipennis, the photograph and the stamp clearly to show what's different of them. In most of south-east areas, S. h. longipennis is having large population than nominate subspecies.
