The White-faced Ibis is a species of wading bird found in central and western parts of North America. Birds winter across Mexico and parts of Central America. A separate non-migratory population lives in eastern South America.
White-faced Ibises are colonial breeders, building their nests in short trees or bushes, always near marshes. They feed on a variety of invertebrates that they find by probing into sand or soil with their bills. White-faced Ibises are related to and highly resemble Glossy Ibises.
The world population of White-faced Ibises is increasing, and as of November 2014 their conservation status is least concern.
Details & Statistics
The White-faced Ibis is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. 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 appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely 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.
