 family), found in the rain forests from S Mexico to Costa Rica at altitudes of up to 9,000 ft (2,745 m). It is strikingly beautiful, with a crested head, bronze-green back, and crimson and white underparts. Quetzals nest in holes, and lay from two to four eggs per clutch. The male shares incubation duties with the female. The nesting hole has a single entrance, not two as was once believed. The Aztec and Maya used the 2-ft (61-cm) shimmering green tail plumes of the breeding male ceremonially and worshiped the bird as the god of the air, associating it with the god QuetzalcoatlQuetzalcoatl
[Nahuatl,=feathered serpent], ancient deity and legendary ruler of the Toltec in Mexico. The name is also that of a Toltec ruler, who is credited with the discovery of corn, the arts, science, and the calendar.

(Pharomachrus mocino), a bird of the order Trogoniformes. The body (without the tail) measures approximately 40 cm long. The head, breast, and back are an iridescent green, the lower part of the breast and the abdomen are crimson, and the tail is black and white and entirely covered by very long (up to 80 cm) upper coverts. The bird inhabits the mountain rain forests of Central America, from southern Mexico to western Panama. It nests twice a year in tree hollows, producing two pale blue eggs at a time. The quetzal feeds on small fruits. The young are initially fed insects and small lizards, then fruits. The quetzal is the national bird of Guatemala.

In quetzals the sexual dimorphism is evident in adults (Sibley & Monroe 1990) but not in the juveniles stages because they are very similar in feather coloration, and practically they can only be distinguished by bill color (yellow in males and dark-brownish in females) (Howell & Webb 1995).
Most of quetzals were caught from its nests so they were different individuals, but the relatedness level among them still unknown.
Here, we carried out a morphometry analysis only in adult quetzals,17 quetzals caught during the blood sample collection were adults of P.
Blood sample collection: For genetic analysis, we used 26 blood samples (25 samples from trapped quetzals and one of a male of unknown origin) obtained during the breeding seasons of 2000 and 2001.
Therefore, we designed long-template amplifications and cloning experiments to analyze the following possibilities: 1) the control region has a copy within a single mitochondrion (partial or complete control region), 2) single individuals have mitochondria with different sequences (heteroplasmy), and 3) quetzals have pseudogenes (nuclear copies of partial or complete control region mtDNA).

Ornithologists are also studying quetzals in Costa Rica's Monteverde region, where sightings attract droves of nature lovers and birdwatchers hoping to catch a glimpse of the elusive bird.
Moreover, the number of Guatemalan quetzals is difficult, if not impossible, to peg because no one has done such a study.
Ironically, due to encroaching civilization and the popularity of the place, quetzals are seldom seen in the very reserve set aside to shelter them.
Rain is almost constant from May through September, the best months to observe quetzals because this is when the breeding season is in full swing and the males flaunt their brightest plumage hoping to attract females.
Quetzals are monogamous, with females choosing males who, unlike most birds, take all active part in hatching the blue eggs laid in abandoned woodpecker holes high up in the trees.
