Here are the answers to Duck 57 from a very hot and humid Lusaka
1) Reed Cormorant The only small inland cormorant. Br. Plumage glossy black (illustrated); bare yellow-orange skin turns red during courtship. Non-br. Overall paler and browner, eyes not as bright red. Juv. Browner above, throat grey and underparts whiter; eyes pale Body glossy black, apart from long white filoplumes on sides of face behind eye.
2) Southern Pochard Dark brown head and upperparts, red eye and pale blue-grey bill
3) African Rail Long bright red bill, eyes and legs distinctive. ♀ is shorter-billed and with markings slightly less distinctive. Juv. Duller, underparts washed brown; bill blackish, legs and feet dark brown.
4) Common Moorhen Combination of white flank stripe, red base to yellow tipped bill and rounded red frontal shield diagnostic.
5) Ruff Has distinctive scaling or scalloped upperparts, thickset appearance and shortish, dark stout bill (pink to orange-red in br). Legs orange coloured, though this sometimes varies in shades of yellow, pink, vermilion or brown. Birds with bright orange/red legs could be mistaken for Common Redshank but lack streaked underparts, and in flight the white secondaries. A small proportion of ♂'s are whitish on head, upperparts and breast.
6) Cape wagtail Drab grey-brown plumage makes it unlikely to be confused with any other wagtail.
7) Malachite Kingfisher The key distinguishing feature is the blue crown plumage that extends down to the eye.
8 ) Little Stint - This one gave lots of problems The most common small wader in the region. Very small with a short bill, and wings that project beyond the tail Confusing species: Red-necked Stint has longer wings and tail and shorter legs (little leg visible above intertarsal joint); bill slightly shorter, heavier at base and more bulbous-tipped; head proportionally larger and, when seen head-on, appears broader across crown; forehead also less rounded and sloping. Readily separable in br plumage; sides of face, neck, and upper breast plain brick red, not streaked. Non-br ad has scapulars and coverts usually wholly pale grey (not brown-grey), with contrasting black feather shafts (not diffuse dark feather centres, although this feature less useful as feathers wear). Breast has only grey lateral patches, indistinctly streaked. Juv has strong (not weak) contrast of pale coverts, tertials and lower scapulars with darker upper scapulars and mantle. Long-toed Stint has upright, long-necked, long-legged, squarer-headed appearance; pale supercilia do not meet on forehead. Bill black, but most with pale base to lower mandible. Legs and feet yellow-grey or yellow-brown to greenish (very rarely greenish in Little Stint)1,5. Temminck's Stint also has greenish legs (short) and more elongate appearance due to longer wings; plumage rather plain above with heavy grey-brown breast band and diagnostic white outer tail.

After the second picture I'm sure everyone knows it's juvenile Saddlebill Storks
