Honduran Emerald Amazilia luciae is currently listed as Critically Endangered under criterion B1a+b(i,ii,iii,v) on the basis that its Extent of Occurrence (EOO) was estimated at 12 km2, within which its habitat is severely fragmented and its population is suspected to be in decline owing to continued habitat loss and fragmentation caused primarily by conversion of land to pasture and cultivation (Anderson et al. 1998, M. Bonta in litt. 1999).
Recent records signifying the rediscovery of the species in Santa Barbara department (Anderson et al. 2010) have extended the species’s known current range into western Honduras, whilst improved knowledge and mapping of its range in central-northern and central-eastern Honduras have further increased the area over which the species is thought to be extant. The species has also been shown to inhabit semi-deciduous woodland in western Honduras, indicating that it is not restricted to thorn forest as previously thought, increasing the area of suitable habitat (Anderson et al. 2010).
Updated BirdLife range map for Honduran Emerald
Following edits to the species’s range map, its EOO is now estimated to be 400 km2 (calculated from the areas over which the species is considered probably extant). This suggests that the species is no longer qualifies as Critically Endangered under the B criterion, although the species is still suspected to be in decline owing to ongoing habitat loss. It is therefore proposed that the species be downlisted to Endangered under criteria B1a+b(i,ii,iii,v) and C2a(i), on the basis that it has an EOO estimated at less than 5,000 km2, in which its population, until further information is available, is still estimated to number fewer than 2,500 individuals, with all sub-populations numbering no more than 250 individuals, and its habitat is severely fragmented, with continuing declines suspected in its EOO, Area of Occupancy, area, extent and/or quality of habitat and number of mature individuals. The population is still suspected to be declining at a rate of 30-49% over 10 years (estimate of three generations).
Comments on this proposed category change are invited and further information on this species is requested, including an up-to-date estimate of the population size, which is currently put at 250-999 individuals, and details of the severity of threats, including the likely rate of habitat loss.
