Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

2009

Assessor/s:

BirdLife International

Reviewer/s:

Bird, J., Butchart, S.

Justification:
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

History:

Habitat and Ecology [top]

Habitat and Ecology:	Behaviour The migratory status of this species is poorly known¹ but some populations may undergo partial intra-African dispersive movements in response to rainfall^{1, 4, 5}. The species breeds opportunistically throughout the year although nesting usually peaks between April and September in the tropics, between July and December in the south and between July and September in Madagascar¹. It nests in solitary pairs with territories^{1, 4} stretching 80-150 m along the shore⁵, and usually forages singly, in pairs or in small flocks of 6-10 up to 20 individuals (very rarely in larger groups of 40 individuals)⁴. It roosts solitarily or in groups¹, occasionally forming loose roosting flocks of more than one hundred individuals in the winter⁵. Habitat The species requires clear, firm sand, mud or gravel shores for nesting, foraging and roosting^{1, 2}. It inhabits the edges of inland freshwater lakes¹, temporary or muddy pools^{1, 2} and rivers¹, streams with shingle banks², rice-paddies (Madagascar)⁶, and the margins of artificial water-bodies (e.g. sewage tanks)¹. It also occurs along the coast on the edges of intertidal mudflats^{2, 6}, sandy beaches^{1, 2}, coastal lagoons, estuaries^{1, 5}, tidal pools⁵, and mangroves⁶ where shows a preference for the least saline areas¹. Diet Its diet consists of adult and larval aquatic and terrestrial insects, crustaceans, small molluscs and worms¹. Breeding site The nest is a simple scrape placed on sand, dry mud¹, shingle³ or on rocks close to water¹.
Systems:	Terrestrial; Freshwater; Marine
