Population justification: The known population at seven recently discovered sites in Lara and Falcón in 1996 was c.35-94 pairs (Boesman 1997). By 2012, there were 25 additional known sites, with further surveys likely to discover additional localities, so the total population is probably several times the known figure (Boesman 1997, Sharpe et al. 2001, V. Morón-Zambrano in litt. 2012, C. J. Sharpe in litt. 2015, Sharpe and Ascanio 2015). Therefore, although the population at known sites was thought not to exceed 250 individuals in 2008 (Ascanio and Sharpe 2008), it is now believed to exceed 1,000 individuals (Sharpe and Ascanio 2015); the total population is therefore placed in the band 1,000-2,499 mature individuals, equating to 15,00-3,750 individuals in total.

Trend justification: A slow and on-going population decline is inferred to be taking place owing to the continued loss and degradation of wetland habitats.
