Hi John,
Why is it necessary to obtain a photo of large numbers of GNDs together, when you accept that they do flock, and the birds at the start of this thread can be identified as GND on plumage and structural features...?
By the way, half decent numbers of Black-throats DO occur over here, mainly at Ballyvaughan, but ,anywhere else, GND is far more likely, and, as I found out when I first visited Ballyvaughan, GND is also common even there.
Regards,
Harry
