Abstract Ocellated quail is a poorly known and little studied species, rarely observed in the wild. It occurs from south western Mexico through Guatemala, El Salvador, Honduras and north central Nicaragua. Montezuma and ocellated quail are biogeographically separated by the tropical lowlands of the Isthmus of Tehuantepec, in south western Mexico and are believed to be allopatric replacement forms. Collections for museums and observations in the wild have been sparse over the last 50 years. This paper reports recent observations and their proximity to protected areas. Keywords Cyrtonyx, El Salvador, Honduras, Mexico, Near-threatened, ocellated quail. Introduction threatened in 2004. Due to insufficient data (Data Deficient) a recent evaluation resulted in Johnsgard (1973) reports that ocellated quail retaining the current threat category (Birdlife Cyrtonyx ocellatus can be distinguished from its International, 2008). This paper reports on closest relative, the Montezuma quail C. recent sightings of the species in relation to montezumae of southern Mexico, by reduced protected areas within its range and suggests white lateral spotting to their anterior portions that its threat category should be upgraded to and dark chestnut posterior flank spots in Vulnerable. Montezuma quail. On male ocellated quails their midbreast and upper abdominal areas are much lighter, generally buffy or slightly tawny colour and instead of gray flanks with chestnut spotting they have chestnut flanks with black and gray cross-markings (FIG . 1). While separation of the male ocellatus and montezumae is fairly easy (by lack of the chestnut coloured flanks in ocellatus ), females are very similar (FIG . 2) with the only difference being that ocellatus is, on average, only slightly less buffy dorsally (Johnsgard, 1988). Binford (1989) states that in Mexico the species occurs from 1,000 - 3,000 m in upland oak- shrub vegetation. Similarly, in Central America, the species’ preferred habitat is considered to be open pine woodlands and adjacent grassy slopes and fields from 1,500 - 3,000 m in the central highlands (Howell & Webb, 1995). Considered as an “indicator species” of the pine-oak zone with its dense herbaceous understory, it feeds on acorns, bulb-bearing forbs and seeds of grasses and sedges. This flora is able to survive selective logging and infrequent fire, but is less tolerant of FIG . 1 Male ocellated quail, front, back, grazing.
