NT
Belted Flycatcher Xenotriccus callizonus



Justification

Justification of Red List Category
This species is classed as Near Threatened because it is restricted to fewer than 10 locations in a moderately small range, which is suspected to be in decline owing to the clearance of its habitat. Research is required to assess the population size and extent of the threats to its habitat. The results of such studies could influence the listing of this species.

Population justification
Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification
The population is suspected to be in decline owing to on-going habitat destruction.

Distribution and population

Xenotriccus callizonus is uncommon and locally distributed in south Mexico (Chiapas), Guatemala and extreme north-west El Salvador (Howell and Webb 1995). It is most common at El Sumidero, Chiapas, and not well known beyond this location (del Hoyo et al. 2004).

Ecology

This species is found in dense scrubby (and especially oak) woodland at elevations of 1,200-2,000 m  (Howell and Webb 1995). It feeds on insects, searching from a low branch and then sallying out to capture its prey in the air or from foliage (del Hoyo et al. 2004). Its nest, in which it lays three eggs, is a cup made of fine grass and other plant fibres, situated in a fork of a shrub (del Hoyo et al. 2004).

Threats

Suitable habitat is undergoing widespread clearance throughout the region, owing principally to coffee cultivation (Stattersfield et al. 1998) and logging, as well as uncontrolled fires (del Hoyo et al. 2004). Its favoured habitats, pine-oak forest and woodland, have suffered heavy deforestation throughout its range (K. Eisermann in litt 2010).

Conservation actions

Conservation Actions Underway
No targeted conservation action is known for this species; however, it occurs in El Sumidero National Park (Chiapas, Mexico) and Montecristo National Park (El Salvador) (K. Eisermann in litt 2010), at least.

Conservation Actions Proposed
Conduct surveys to assess the total population size. Carry out regular surveys to monitor population trends. Monitor rates of habitat loss and degradation. Protect suitable habitat.
