What appears to be a Grey Crowned Crane Balearica regulorum was photographed flying north over Juba on 31 October 2013; this would constitute the first for South Sudan, where the congeneric Black Crowned Crane B. pavonina is common.

The following sightings were made in the Juba area in March–June 2012. Rock Pratincole Glareola nuchalis, marked as rare or vagrant in Nikolaus (1987. Distribution Atlas of Sudan’s Birds), was found to be common in early March. Other March records include a Eurasian Spoonbill Platalea leucorodia, an African Cuckoo Hawk Avecida cuculoides, a Steppe Buzzard Buteo buteo vulpinus, and an adult Common Black-headed Gull Larus ridibundus (few previous records in South Sudan and / or new one-degree square), as well as a Spot-flanked Barbet Tricholaema lacrymosa (possibly the first record away from the Didinga Mountains). On 29 April, more than 12 European Honey Buzzards Pernis apivorus moved north along the White Nile, with an estimated 6,000 White-winged Terns Chlidonias leucopterus passing in three hours during the afternoon. Several Black Herons Egretta ardesiaca were present in June, whilst a Lesser Moorhen Gallinula angulata was seen on 16th and an African Crake Crex egregia on 22nd; all three species are considered rare by Nikolaus (1987).
During a short stay in Juba, the capital of South Sudan, in late June 2009, two species were observed that are not marked for the relevant square in Nikolaus (1987. Distribution Atlas of Sudan's Birds): Striated (Green-backed) Heron Butorides striata (one on 27th) and Short-winged Cisticola Cisticola brachypterus (a few singing on 29th). Other records included a Harlequin Quail Coturnix delegorguei flushed on 29th; a male Pennant-winged Nightjar Macrodipteryx vexillarius in breeding plumage on 26th and 29th, with two females on 29th; and a Black-breasted Barbet Lybius rolleti on 26th.
On 18 July 2010, another four species were added to the same Juba square, all seen on or beside the Nile: Black Heron Egretta ardesiaca (one), Osprey Pandion haliaetus (two), Lizard Buzzard Kaupifalco monogrammicus (one) and Rock Pratincole Glareola nuchalis (three), whilst two Striated Herons were also noted.
Notable species observed near Juba in October 2008 include an adult Beaudouin’s Snake Eagle Circaetus beaudouini on 25th, a Steppe Buzzard Buteo buteo vulpinus on the same date, with two the next day and another single on 28th, a Eurasian Hobby Falco subbuteo on 26th, and several European Bee-eaters Merops apiaster and a Great Reed Warbler Acrocephalus arundinaceus on 25th.
