Hi! This is my first post to this forum.
I've been visiting regularly a place where an adult male and a 1st winter male Siberian Blue Robin bathe in the late afternoon.
Yesterday, another robin(?) came out at about the same time as the 1st winter male Siberian Blue. (Didn't see the adult male).
At that time I was thinking maybe this is a subadult female of the Siberian Blue. But from the field guides it doesn't seem to any kind of Siberian Blue. Some other Luscinia robin perhaps? But then again I can't find any robin with such yellowish undersides from the Malaysian checklist.
So what can this be?
