Hi Bart47,
Birding in the Northern parts of Kruger is always an amazing experience.
Species to look out for are..
Yellow Bellied Greenbul (Pafuri Picnic Spot)
Wattle Eyed Flycatcher (Pafuri Picnic Spot)
Retz Helmet Shrike (Pafuri Picnic Spot)
African Yellow White Eye (Pafuri Picnic Spot)
Lemon Breasted Canary (Crooks Corner)
African Pygmy Kingfisher (Crooks Corner)
Tambourine Dove (Crooks Corner)
African Cuckoo Hawk (Crooks Corner)
Trumpeter Hornbill (Crooks Corner)
Crowned Hornbill (Crooks Corner)
Broad Billed Roller (Punda Maria)
Racket Tailed Roller ( Mohonie Loop)
Eastern Nicator ( Punda)
These are just some of the nice species to get while up here

Try the Mohonie Loop around Punda Maria for grey Headed Parrot and Racket Tailed Roller, and if your lucky Southern Hyliota. The camp itself provides amazing birding, with Pink Throated Twinspot often makes an appearance here at the bird bath near the reception area. Crowned Hornbill is often found inside the camps boundaries as well.
Check the area around reception and the luxury tents for Bearded Scrub Robin, White Throated Robin Chat and Eastern Nicator.
Barn Owl is also often found inside the camp at night and one must keep their ears open for their screeching call.
Red Faced Cisticola is also common in the area and one must keep an eye open for them near the waterways and ponds. Temmincks Courser is also common in this area, but extremely hard to find. Search the open grasslands and recently burnt areas.
Take a night drive, as this may produce both Spotted Eagle Owls and White faced Scops Owl, and maybe even Verouxes Eagle owl. Fiery Necked Nightjar and Bronze Winged Courser may also make a guest apearance. Just make sure you tell your guide that you are interested in the birdlife as well, and im sure he will acocmodate you.
Hope this helps
