23-3-2017 TROGON LODGE COSTA RICA - RESPLENDENT QUETZAL (Pharomachrus mocinno)

The resplendent quetzal (Pharomachrus mocinno) is a small bird found in southern Mexico and Central America that lives in tropical forests, particularly montane cloud forests. They are part of the family Trogonidae and have two recognized subspecies, P. m. mocinno and P. m. costaricensis. Like other quetzals, the resplendent is mostly omnivorous; its diet mainly consists of fruits of plants in the laurel family, Lauraceae, but it occasionally also preys on insects, lizards, frogs and snails.

The species is well known for its colorful and complex plumage that differs substantially between sexes. Males have iridescent green plumes, a red lower breast and belly, black innerwings and a white undertail, whilst females are duller and have a shorter tail. Grey lower breasts, bellies, and bills, along with bronze-green heads are characteristic of females. These birds hollow holes in decaying trees or use ones already made by woodpeckers as a nest site. They are known to take turns while incubating, males throughout the day and females at night. The female usually lays one to three eggs, which hatch in 17 to 19 days. The quetzal is an altitudinal migrant, migrating from the slopes to the canopy of the forest. This occurs during the breeding season, which varies depending on the location, but usually commences in March and extends as far as August.

The resplendent quetzal is considered near threatened on the IUCN Red List, with habitat destruction being the main threat. It has an important role in Mesoamerican mythology, and is closely associated with Quetzalcoatl, a deity. It is the national animal of Guatemala, being pictured on the flag and coat of arms; it also gives its name to the country's currency, the Guatemalan quetzal.

This species inhabits amidst lush vegetation, in specially moist rainforests at high elevations (900–3,200 m (3,000–10,500 ft). They populate trees that make up the canopy and subcanopy of the rainforest, though they can also be found in ravines and cliffs. It prefers to live in decaying trees, stumps, and abandoned woodpecker hollows. The vivid colors of the quetzal are disguised by the rainforest. The resplendent quetzal can be found from southern Mexico (southernmost Oaxaca and Chiapas) to western Panama (Chiriquí). The ranges of the two subspecies differ: P. m. mocinno is found in southern Mexico, northern El Salvador, and northwestern Nicaragua, Guatemala and Honduras, while P. m. costaricensis is found in Costa Rica and western Panama. The geographical isolation between the two subspecies is caused by the Nicaraguan depression, a 50 km (31 mi) wide, 600 km (370 mi) long bottomland that contains the two largest lakes in Central America, Lake Managua and Lake Nicaragua, and the deficiency of the breeding habitats in regions adjoining to. The quetzal migrates from its breeding areas in the lower montane rainforest to the pre-montane rainforest on the Pacific slopes for three to four months (July–October), after which they move across the continental divide to the Atlantic slopes.

Quetzal's abundance in its mating areas is correlated with the total number of fruiting species, although the correlation between quetzal abundance and the number of fruiting Lauraceae species is only marginal.
