Population justification: The population is assumed to fall in the band 50-249 individuals, based on a paucity of recent records and the restricted number of known localities. This equates to 33-166 mature individuals, placed here in the band 50-200 mature individuals. For the sites where there are recent records (i.e. since its initial collection in the 1940s-1950s), the population is estimated to be at least 20 pairs in the Morrocoy-Tucacas area of Falcón and 15 in Patanemo, Carabobo. Verification of this estimate is desirable.

Trend justification: This species's population is suspected to be rapidly decreasing as its mangrove habitat is lost or degraded due to coastal housing, touristic and industrial developments, pollution from domestic sewage and agricultural run-off, sedimentation and the restriction of water flow by road-building.
