Hi everyone

Here are the answers for challenge #33 of 2013.
There were 19 participants with an average score of 4.89/8, or 61.18%.
Well done to everyone who took part :thumbs_up: and a big well done to Ladybirder who got full marks :clap:

#1
Image
White-bellied (Barrow’s) Korhaan – (8/19)
Both of the Black Korhaans have white greater wing coverts. Karoo Korhaan doesn’t have the white face, and the remiges and primary coverts are more dark brown than black. The buff windows on the primaries are more extensive, and Karoo Korhaan also lacks the buff greater wing coverts that this bird has. Blue Korhaan would show a noticeable amount of blue on the primaries and greater primary coverts. Ruppell’s Korhaan has much more white, and much less black on the upper-wings, with the black being restricted to the trailing edge and wing-tips They also lack the buff greater wing coverts. The only Korhaan that matches all the features is White-bellied Korhaan, with the white face, black primaries and secondaries, buff/white panel on the primaries, and buff greater wing coverts. (Photo taken: Rhenosterkop, Gauteng)

#2
Image
African Rock Pipit – (9/19)
Most people who got this one wrong said a Warbler of some sorts, mostly Sedge or Willow Warbler. The jizz of this bird is wrong for a Warbler, and also you will NEVER see either of those perched out in the open on a rock like this. You must always try look at more than just the bird, and the habitat is a big clue in this picture. The jizz, bold, almost Robin-like, supercilium, and yellow markings on the wings are diagnostic for African Rock Pipit. (Photo taken: Greylingstad, Mpumalanga)


#3
Image
Lazy Cisticola – (10/19)
A Cisticola with a plain back leaves only Neddicky, Short-winged Cisticola and Lazy Cisticola. Nobody said Short-winged Cisticola. The most regular incorrect answer was Neddicky, but the tail of this bird is much too long for Neddicky. Some people answered Tawny-flaked Prinia, but that has a much more slender jizz, distinct supercilium, and red eye-ring. The long tail cocked up like this is a typical pose for Lazy Cisticola. (Photo taken: Ezemvelo Nature Reserve, Gauteng)

#4
Image
Great Sparrow – (15/19)
The most frequent incorrect answer here was Common Chaffinch, but that has much more extensive grey on the hind-neck, and also much more brown and black on the back, as opposed to rufous/chestnut like this bird has. Habitat is also wrong for Chaffinch. House Sparrow would have a more brown colouring on the sides of its head, not the rich chestnut colouring that this bird has. Also on House Sparrow the grey is restricted to the nape, and doesn’t extend onto the mantle. (Photo taken: Fafung Village, North West)



#5
Image
Bennett’s Woodpecker (female) – (18/19)
Not too many problems with this one. The combination of the spots underneath, spotted fore-crown, red hind-crown and brown check and throat patches means that this can only be female Bennett’s Woodpecker. (Photo taken: Borakalalo Game Reserve, North West)

#6
Image
Gabar Goshawk (juv) – (17/19)
Also not too many problems here. The legs are too short to be either of the Chanting Goshawks, and also juvenile Chanting Goshawks have a more solid brown colouring on their breasts, as opposed to streaks. Juvenile Gabar Goshawk is the only accipiter with a combination of a streaked chest and barred belly. In this photo, if you look closely you can also see the white bar on the secondaries which is a diagnostic feature of Gabar Goshawk in all age groups (Photo taken: Kgalagadi Transfontier Park, Northern Cape)

#7
Image
Bradfield’s Hornbill – (11/19)
This one is only really between three candidates; Crowned, Monteiro’s and Bradfield’s Hornbill. Everyone said one of these 3 birds. Crowned is overall darker, and also has a more red, as opposed to orange bill. There is also always a visible amount of yellow at the base to the bill of Crowned, and Crowned always has a casque on the bill, whereas this bird has no casque. Monteiro’s Hornbill has white spots on the wings, white secondaries and distinct white outer-tail feathers which this bird lacks, and Monteiro’s also usually shows a dull yellow base to the bill. (Photo taken: Moremi Game Reserve, Botswana)

#8
Image
Fawn-coloured Lark – (5/19)
This turned out to be the toughest bird of the challenge. The shape, colouring, bold supercilium, and robust bill should get you to the Lark family. Sobota Lark is much more heavily marked on the breast, head and face than this bird. Stark’s Lark is a lighter grey colour on the back and head, as opposed to rufous like this bird. Also it is quite uncommon to see Starks Lark perched on a bush; it is much more commonly seen on the ground. Dune Lark is the most similar looking to this Lark, but Dune Lark always shows some degree of markings on the breast. Therefore, the combination of the rufous colouring on the head, bold white supercilium, lack of any other facial markings such as a malar stripe, and totally unmarked white breast only fits for Fawn-coloured Lark. (Photo taken: Kgalagadi Transfontier Park, Northern Cape)
