Cinnamon-tailed Sparrow Peucaea sumichrasti
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species is listed as Near Threatened because it has a small range, in which it is potentially threatened by habitat degradation and infrastructure development. Research is required to assess the impact of these potential threats. If these threats are found to be driving declines, the species may qualify for uplisting to a higher threat category.

Cinnamon-tailed Sparrow 17.5 cm. A largish grey and rufous sparrow with a well marked facial pattern. Upperparts grey brown streaked blackish, underparts pale grey with whitish belly and cinnamon flanks and undertail, crown rufous streaked darker with grey median stripe, black moustachial and malar stripes, ear coverts greyish. Similar spp The rufous tail and prominent black moustachial and malar stripes are distinctive within its range. Rusty Sparrow A. rufescens is larger with darker ear coverts and more rufous upperparts and wings, Oaxaca Sparrow A. notostricta is superficially similar but has grey brown tail, no moustache and has grey brown (not rufous) lesser coverts. Voice Song is a series of high pitched metallic notes, pairs often duet, calls include a high pitched double note. Hints Shy and secretive except when singing, usually from an exposed perch.

Distribution and population
Peucaea sumichrasti has a small range on the Pacific slope of south-east Oaxaca (west to Las Tejas and through the río Tehuantepec basin to Rancho las Animas) and extreme south-west Chiapas, Mexico (Binford 1989, Howell and Webb 1995, AOU 1998).

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 stable in the absence of evidence for any declines or substantial threats.

This species is fairly common to common up to 900 m in arid lowland scrub and on the edge of, and openings within, tropical deciduous forest (Howell and Webb 1995).

The Pan-American Highway has led to fragmentation of habitat within its restricted range (Stattersfield et al. 1998). Many forest areas are now degraded or secondary, but whether this has had a detrimental impact on this species is unclear.

Conservation Actions Underway
No targeted conservation action is known for this species. Conservation Actions Proposed
Carry out surveys to assess the total population size. Monitor population trends through regular surveys. Study the species's ecology, including habitat use. Assess the impact of the Pan-American Highway and habitat degradation on the species. Grant protection to areas of suitable habitat.
