 Quail (for the male's striking pattern), and the Fool Quail (for its behavior).

Description

At about 22 cm (8.75 in), it is one of the shortest quails of North America, although it weighs 180 g (6 oz), the same as some Callipepla quails that are several centimetres longer. It has an even plumper build and shorter tail than other quails.

Both sexes have the back and wing coverts tan with longitudinal light-buff streaks formed by the feather shafts and circular or transversely oblong black spots arranged in bars. A crest on the nape makes the profile distinctively long front-to-back. The bill is black above and bluish-gray below. The adult males have a striking, swirling black-and-white face pattern. A single tan plume lies flat over the crest. Their sides are blue-gray (often looking black) with bold spots, which in northern birds are white and in southern birds are white towards the front and chestnut towards the back. The middle of the chest and belly is dark brown in northern birds, lighter and tawnier in southern birds. Females have a suggestion of the male's face pattern. Their underparts are light brown with a few fine black shaft streaks and other lines. Juveniles resemble females, but the underparts are grayish with white shaft streaks and black dots. Immature males develop the adult side pattern early but do not develop the face pattern till early winter.

An unusual feature of this species is the long, sickle-shaped claws, which it uses for digging.

Voice

The assembly or territorial call is "six to nine notes descending in pitch", "a far-carrying, descending, quavering whinny". The male's "song" for pairing is "an eerie, melancholy, vibrant, descending whistle vwirrrrr" or "an insect-like buzzing that starts at a high pitch and descends". It is given from the ground, whereas other quails sing on such perches as the tops of fenceposts or bushes. There are other calls as well.

Taxonomy

The southern populations are sometimes considered a separate species, Cyrtonyx sallei. On the other hand, the Montezuma Quail is sometimes considered conspecific with the very similar Ocellated Quail

, with grass at least 30 cm (1 ft) tall. Slopes of hills and canyons are particularly favored. The range is decreasing and becoming fragmented.

Behavior

In fall, Montezuma Quail do not form large groups, as most American quail do. An average covey consists of eight birds, just parents and their offspring, and coveys bigger than 25 birds have been reported. At night, birds in a covey roost on southeast-facing slopes, gathered around a rock or tussock, facing outward.

These birds are quite sedentary. A pair or covey typically forages within 50 m of the place where it foraged the day before. Coveys' territories in fall and winter are only 1 to 5 hectares; in the breeding season, pairs spread out and territories may be as big as 50 hectares. Otherwise, no seasonal movements are known.

In the presence of humans, Montezuma Quail crouch motionless in tall grass instead of running. They may allow an approach as close as 1 metre before flying (taking off with a "loud, popping wing noise") and on rare occasions have been caught by hand.

Feeding

The Montezuma Quail eats insects, especially in summer, as well as plants. Particularly important plant foods are Oxalis

 sometimes contain bulbs of plants that have no above-ground growth at that season; how the birds find such bulbs is unknown.

Reproduction

Males begin singing in February or March, but nesting does not start till July or August, the season of "monsoon" rains throughout its range. The long delay between pairing and nesting is unusual for quails. The nest is also unusual: a grass dome with one entrance, more elaborate than most nests in the family. The clutch comprises about 11 eggs (ranging from 6 to 12), which are "whitish" or "chalk-white". Incubation lasts about 25 days by both the male and the female(two days longer than that of most American quails). Males help brood the young; at least in captive birds, they may also help build the nest and incubate the eggs.
