LC
White Ibis Eudocimus albus



Justification

Justification of Red List Category
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 stable, 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 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.

Population justification
The global population is estimated to number 210,000-360,000 mature individuals (Wetlands International 2020).

Trend justification
The population in Central and South America is thought to be stable, while the population in North America is increasing (Rosenberg et al. 2019; Wetlands International 2020). In North America, the population has increased by about 65% over the past three generations (23 years, Pardieck et al. 2018). Overall, the population is here tentatively assessed as stable.
