VU
Sinaloa Martin Progne sinaloae

Justification
This species has been uplisted to Vulnerable because increased knowledge suggests that the total population  is small and continuing to decline. The reasons for this are unclear.

Distribution and population
Progne sinaloae breeds in pine-oak forest and semi-open habitat at nine sites on the west slope of the Sierra Madre Occidental. It still appears to occupy its traditional breeding range from Sonora to Michoacán, with recent records from Guerrero (Lethaby and King 2010). Breeding has been recorded historically in Sonora, Chihuahua, Sinaloa, Nayarit , Jalisco and Michoacán states, Mexico (Phillips 1986, Lethaby and King 2010); of these, it is still known to breed in Sinaloa and Jalisco (Lethaby and King 2010). It has been recorded on migration in Mexico and casually in Guatemala (Turner and Rose 1989, Howell and Webb 1995) and Belize but its wintering range, conservation status and population trends are unknown.



Population justification
Lethaby and King (2010) consider it unlikely that the population numbers more than a few thousand, and based on current knowledge, a population estimate of fewer than 10,000 mature individuals seems realistic.

Trend justification
The population is suspected to be decreasing. As Lethaby and King (2010) point out, historical records typically comprised of multiple specimens from a given location and include statements such as 'common', 'quite a colony', 'up to 15', and 'up to 30' that clearly indicate the existence of sizeable colonies, whereas recent records are usually of migrants in the lowlands, with the only definite breeding record being a colony of just 2-6 birds (Lethaby and King 2010).

Ecology
This very poorly known species breeds in small colonies in pine-oak forest and semi-open habitat in mountainous areas (Turner and Rose 1989, Howell and Webb 1995) but its wintering grounds (and habitats) are unknown. Historical and contemporary records are compiled and analysed by Lethaby and King (2010).

Threats
Unknown.

Conservation Actions Underway
None is known. Conservation Actions Proposed
Survey the breeding range to map its extent and assess the size of the breeding population (Tobias et al. 2006, Lethaby and King 2010). Special attention should be given to areas with post-1980 records (Lethaby and King 2010). Attempt to locate wintering population in South America and assess threats there. Thoroughly check mixed non-breeding roosts of Progne martins in Amazonia for this and P. dominicensis, perhaps through mist-netting (Tobias et al. 2006).
