Thanks for the advice so far. Wildtuinman, a couple of birds I would rather like to see would include:
Whitebacked Night-Heron - Your best bet will be Shipandane, they were breeding there a few months ago. Lake panic also had them as well as Sweni hide.
Whitebacked&Fulvous Ducks; - Ducks are seen on most water holes.
Crake species; - Black crake is present @ Lake Panic, the other crakes will take some time/luck finding.
Greater Painted-Snipe; - The Mopani and Punda Maria(Klopperfontein) areas seems to be a place to find these, I myself have never seen them.
African Snipe; - Never seen them in Kruger either, but try aforementioned areas.Temminck's&Bronzewinged Coursers; - Bronze-winged courser is a definite on nightdrives from Croc bridge. Temminck's frequesnt recently burnt areas. Some folks say Shingwedzi's back gate area is a good spot. I've never seen them either.
Bluespotted Wood-Dove; - Pafuri.
Cuckoo species; - Cuckoo's can be found all over the Park in summer time. I suggest you learn their calls and then look for them as soon as you hear one.
Owls; - Owls too can be found all over the Park. Pretoriuskop is a very good spot for spotted-eagle owl and barn owl. Lower Sabie produce sightings of barred owlet and white-faced scops owl. Scops owls can be found @ afsaal picnic spot and satara. Pearl-spotted owlets are regulary seen during the day in the Satara area. Listen for their calls. I suggest you do a nightdrive to find owls.
Greyheaded&Striped Kingfishers; - Berg-en-dal provided me with striped kingfisher once. Grey-headed I yet have to find.
Rackettailed&Broadbilled Rollers; - Pafuri
Lark species; - Any grassy area. Satara seems good habitat for these.
LBJ's; - Can be found anywhere in the Park. Again I suggest you learn their calls. Satara seems good.
Eremomela's; The above I have no good exact locations for. But the are to be found in Kruger.
Marico&Pale Flycatchers; Lesser Grey,
Gorgeous Bush, - Haven't got a clue, but do let me know if you find any. Listen for their calls, its one thing hearing them, but another seeing. Berg-en-dal's Matjulu dam have provided me with calls.
Orangebreasted Bush, - Seen in Lower Sabie.
Whitecrested Helmet and Retz's Helmet Shrikes; - Seen in Biyamithi.
Purplebanded&Plainbacked Sunbirds;Violeteared&Orangebreasted Waxbills. - Sorry, can't help withe these.
Hope you find what you looking for!
