This discussion was first published as part of the 2016 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2017 Red List update this post remained open and the date of posting was updated.

This species is poorly recorded, with no population estimate, known from a restricted area of seasonally flooded wetlands in northern Uganda (Collar and Stuart 1985, Byaruhanga et al. 2001, A. Byaruhanga in litt. 2003). It has been recorded at two Important Bird Areas, Lake Bisina (250 km2) and Lake Opeta (570 km2), and also has been found in marshland between these lakes. There are also records from Rhino Camp in Arua and from the Lake Kyoga system near Nakasongola. In August 1996, 47 nests of this species were recorded around Lake Bisina, but it has not been recorded breeding in this area since (Byaruhanga et al. 2001).
It is currently listed as globally Near Threatened, because it has been assumed to have small population which may be declining, but there was no strong evidence to support listing this species as threatened. However, recent analysis as part of a compilation of a list of the Nationally Threated Species for Uganda (WCS 2016), has listed this species as Endangered under criterion B2ab(iii,v), as the species may have a small Area of Occupancy, which may be declining and as such the species is threatened by habitat loss (H. Mugabe in litt. 2016). The Ugandan national Red List does not include an estimate for AOO nor details of how it was calculated, but the threshold for classification as Endangered is 500 km2.
We request any information regarding this listing to confirm whether this species should be uplisted from Near Threatened to Endangered.
