Indian spot-billed duck

Anas poecilorhyncha

Indische vlekbekeend / Flecksnabelente / Canard à bec tacheté


The spot-billed duck is a dabbling duck which breeds in tropical and eastern AsiaThis duck is around the same size as a mallard.

Anas poecilorhyncha (Sibley and Monroe 1990, 1993) has been split into A. poecilorhyncha and A. zonorhyncha following Leader et al. (2006), who presented evidence of sympatric breeding; this treatment is also accepted by AOU. 


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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified but is believed to be 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 (IUCN, 2013).


A combined population estimate of 150,000-1,100,000 individuals was given for A. p. poecilorhyncha and A. p. haringtoni by Miyabayashi and Mundkhur (1999), prior to the recent taxonomic change
