While looking through some old photos of Cut-throat Finch while looking at Andy Adcock's thread, I realised that two photos of a group of this bird in a tree in the Serengeti included something else. A couple of minutes either side of this bird, we saw Long-tailed (Eastern) Paradise Whydah and Pin-tailed Whydah, so I think it is either female or NB-male Eastern, or female Pin-tailed (NB-male would have a red bill I think). There were plenty of breeding males of both species around. Can anyone differentiate between these? Or is it something else? January 2, 2016.
