Cozumel Vireo Vireo bairdi



Justification

Justification of Red List Category
The species has a very small range, however it is uncertain whether it is being affected by habitat loss. It is therefore listed as Near Threatened.

Population justification
Partners in Flight estimated the population to number fewer than 50,000 mature individuals (Partners in Flight 2019), thus it is placed in the band 20,000-49,999 mature individuals here.

Trend justification
The population trend is uncertain; although substantial areas of habitat have been lost to tourist development, much remains intact and the species seems to adjust well to secondary habitats (Brewer and de Juana 2017).

Distribution and population

This species is endemic to the island of Cozumel (Mexico), where it is described as locally fairly common (Brewer and de Juana 2017). Tracewski et al. (2016) estimated the maximum possible Area of Occupancy for the species (calculated as the remaining tree area within the species’s range) to be c.361 km2, rounded here to 360 km2.

Ecology

It inhabits low scrubby woodland, abandoned farmland with scattered bushes, second growth, and thickets in deciduous woodland, and forages in lower and middle vegetation (Brewer and de Juana 2017).

Threats

Substantial areas of habitat have been lost to tourist development, but much remains intact and the species seems to adjust well to secondary habitat (Brewer and de Juana 2017); forest loss throughout the species's range is currently estimated at just ~1.6% per three generations (Tracewski et al. 2016). It could possibly suffer habitat loss caused by hurricanes.
