This species qualifies as Endangered owing to a very rapid population decline. The population is now so small that lower (but still very significant) rates of decline are likely in the future (Collar et al. 1992).
Amazona oratrix has undergone a dramatic population decline, judged at 90% since the mid-1970s, to 7,000 birds in 1994. There are three subpopulations in Mexico: the race magna in Tamaulipas, San Luis Potosí, Veracruz, Chiapas, Tabasco and Campeche; the nominate race from Jalisco to Oaxaca (Roberson and Carratello 1997); and the race tresmariae on the Islas Marías. The race belizensis was widespread in coastal Belize, but is now primarily restricted to central and north-west areas (Clay 1999), mostly in pine-oak forests along the coastal plains (B. Miller in litt. 2007). There is an old report and a 1993 record from Petén, Guatemala (Clay 1999), and "guatemalensis" occurs from Punta Manabique to extreme north-west Honduras (Lousada and Howell 1996). There are conflicting reports that tresmariae is stable (S. N. G. Howell in litt. 1998) and under considerable threat (Low 1995b). On the coast of Michoacán, Mexico, it has been calculated that the species occupies 45.6% of its estimated historic distribution (Monterrubio-Rico et al. 2007). Based on intensive field surveys during 2001-2007, it was verified that the species's range has contracted in Colima state, and it has been extirpated in 11 municipalities in coastal Guerrero state (from Tecpan de Galeana to Marquelia) (T. Monterrubio-Rico et al. in litt. 2007). The combined range decline for Colima, Michoacan and Guerrero is estimated at 3,990 km2 (T. Monterrubio-Rico et al. in litt. 2007). Its Mexican coastal Pacific range may now cover 18,957 km2 split into three fragments (T. Monterrubio-Rico et al. 2010). The population at Punta de Manabique declined by 30% to 70 individuals from 1994 to 2001 primarily because of nest poaching (Eisermann 2003, Eisermann in litt. 2007).

|Population:||The population was estimated at 7,000 individuals in 1994. This is roughly equivalent to 4,700 mature individuals.|
|Habitat and Ecology:||It inhabits dense thorn-forest, savanna, tall deciduous forest and humid riverine woodland, occasionally up to 500 m. Birds favour semi-arid regions in the northern Atlantic lowlands, but more humid savannas further south. In Belize, it inhabits pine savannas and adjacent evergreen forest patches, and "guatemalensis" occurs in coastal scrub, palm savanna and mangroves (Lousada and Howell 1996, Eisermann 2003). Food privation and fire cause occasional wanderings. It nests in tree-cavities and in snags of Roystonea palms (Eisermann 2003), with breeding occurring in February-June. Along the Michoacan Pacific coast in Mexico, the species nests in Astronium graveolens, Brosimum allicastrum and at least five other tree species (T. Monterrubio-Rico et al. in litt. 2007). Nesting success is only 0.5 fledglings per nest (E. C. Enkerlin-Hoeflich in litt. 1994). It feeds on fruit from wild and cultivated trees.|
|Major Threat(s):||Habitat loss has been extensive, with 80% of the Tamaulipas lowlands cleared for agriculture and pasture, and increasing settlement along the Western Highway in Belize (Somerville 1997). In Belize, where much of the suitable habitat lies outside the national protected area system, the regions occupied by the species remain under heavy development pressure (B. Miller in litt. 2007). Palm savannahs at the only known breeding site in Guatemala are used for non-intensive cattle-grazing (Eisermann 2003), which continues to be a threat here (Fundary et al. 2006). Many thousands of individuals of this species are illegally exported from Mexico and some from Belize each year, and it is popular in domestic markets (Low 1995b, Miller and Miller 1997, Somerville 1997). Illegal domestic traffic is intense in Mexico and may account for 38% of the species's recent distributional loss (T. Monterrubio-Rico et al. in litt. 2007). In the Mexican states of Michoacan, Guerrero and Oaxaca, it is mainly nestlings that are taken for the pet trade (T. Monterrubio-Rico et al. in litt. 2007). In Guatemala, it is reported that local military authorities are complicit in the illegal trade of this species, and nest poachers are reported to frequent the species's nesting site (Eisermann 2003, Eisermann in litt. 2007). In addition, hunting for food by local fishermen has been reported from Guatemala (Eisermann 2003, Eisermann in litt. 2007). In Belize, it is hunted and persecuted for damaging crops (S. N. G. Howell in litt. 1998) and is still a victim of the illicit pet trade, capture for which involves the cutting down of nesting trees (B. Miller in litt. 2007). Its range around coastal Michoacán is estimated to have declined by 1,507 km2, of which 576 km2 can not be attributed to habitat loss and thus may be due to poaching for trade (Monterrubio-Rico et al. 2007).|
Conservation Actions Underway
CITES Appendix I. In Mexico it occurs in nine protected areas (T. Monterrubio-Rico et al. in litt. 2007). The race magna occurs in El Cielo, Los Tuxtlas, Pantanos de Centla and Laguna de Terminos Biosphere Reserves. The race tresmarieae is protected in the Islas Marias Biosphere Reserve. The race oratrix occurs in Chamela-Cuixmala Reserve, on the Lagunas de Chacahua, Huatulco National Park, and on the recently created Zicuiran-Infiernillo Biosphere Reserve in Michoacan (T. Monterrubio-Rico et al. in litt. 2007), as well as seven protected areas in Belize (E. C. Enkerlin-Hoeflich in litt. 1994, Miller and Miller 1997, Snyder et al. 2000). The only breeding population known in Guatemala was declared a wildlife refuge in 2005, but effective protection is difficult due to organised crime in the area (Eisermann in litt. 2007). There are several country-wide awareness campaigns in Mexico (Roberson and Carratello 1997). It is bred in captivity, but the reintroduction of captive-bred birds is unfeasible (Low 1995b). Conservation Actions Proposed
Carry out surveys to obtain an up-to-date estimate of the population size. Monitor rates of habitat loss and degradation. Monitor levels of hunting, capture and trade. Enforce trade restrictions. Effectively protect key sites such as Las Colorados Ranch, Soto La Marina/La Pesca, (Tamaulipas), río Naranjo, centred on Las Abritas (San Luis Potosí) and Punta de Manabique. Survey to identify additional important sites. Research habitat use and local movements. Continue to expand awareness campaigns. Develop structured captive-breeding programmes and research the possibility of future release.
