It seems that I have put up a challenge somewhat tougher than I anticipated. Right at the end I finally had a full marks!! The average was 7/10 over the 12 participants.
#1 African Cuckoo
(7) The most common alternatives were Common Cuckoo, which should not have the yellow in the bill extend over the nostril, or Red-chested Cuckoo, which must have red from half the neck downwards.
#2 Pale Form Tawny Eagle
(8) It has a light white line at the edge of the primary coverts, with a lighter window panel. Key distinguisher from Booted Eagle is the full dark tail, where Booted will only have a terminal band.
#3 Broad Tailed Warbler
(10) Most had this one right, but the scalloping under the tail, with the large unkempt tail is the key feature.
#4 Sombre Greenbull
(3) The most difficult one this week. Giss is that of the buls. Uniform olive green uppers narrows it to the Greenbuls. Although this is a young bird, the eye is already the distinct pale of that of a Sombre.
#5 Black Winged Pratincole
(10) Most had this one right.
#6 Red Collared Widowbird
(7) – Again this was a very tricky bird. The Giss should point one in the right direction, but then the fact that the bird is in transition really makes it difficult. This particular bird has much more yellow in its breast than I have ever encountered. Usually looking at what species are alongside can often narrow it down, but in the particular location all 4 South African Widowbirds are present. A fairly regular feature of Red-collared transition is the deeply forked tail which is the most reliable feature to distinguish it from the other.
#7 Streakyheaded seedeater
(6) This one was significantly more difficult than I expected. The heavy streaked head is the key feature, coupled to the white brow and dark cheeks, and white breast with no black on the throat.
8 Lesser Striped swallow
(6) The answers on this one floored me so much that I started doubting my own id. It obviously is a striped swallow. The bad light is what makes it more difficult, but the striping is just too heavy for Greater. The main thing to have looked out for is the rufous extending down the rump of the bird. With the bad light it is more of a dark patch, but this you will not see on Greater
#9 Pearlbreasted swallow
(10) Metallic blue uppers and white breast narrows it to Common House Martin or Pearlbreasted Swallow. There is a black, not metallic facial band from the bill, over the eyes to the ear, which distinguishes it from the Martin
#10 Double Banded Courser
(11) Most have this right. There is no prominent eyebrow, and the start of the two bands on the chest is just visible.
