behaviour
the pavonine quetzal remains poorly studied species, meaning unknown species in terms of behaviour. few studies include quetzal in bird inventories, go more in depth ecology , behaviour of bird.
diet
like quetzals, p. pavoninus frugivore. study looking @ stomach contents of 9 specimens of bird found 8 birds had solely eaten various fruits, whereas other 1 had consumed mixture of fruits , arthropods. other researchers observed similar behaviour, classifying them frugivores. in 2007, short report documented feeding behaviour of couple , newborn. half juvenile’s diet consisted of tree frogs shortly after hatching, while other half reserved variously shaped, sized , coloured fruit. specifically, tree frogs seemed belong 2 genera only: hyla , phyllomedusa, while fruits came lauraceae (near half), followed euterpe precatoria (arecaceae), iryanthera sp. (myristicaceae), pouteria sp. (sapotaceae), guatteria , unonopsis sp. (annonaceae), , tetragastris sp. (burseraceae) in decreasing order of importance. on few weeks took fledge youngling, parents increased proportion of fruit in neonate’s diet.
vocalisations
quetzal vocalizations quite simple in form, loud, , repetitive. while few variations exist on how spell out call of pavonine quetzals, vocalizations resembles descending whistle (« ew ewwo ewwo ewwo ewwo »), followed « chok » note. birds repeat call around 4 times in ten seconds, , composes bulk of known vocalizations. produce alarm call described chattering « wa op-op-op-op », of woodpecker. finally, juveniles able produce short « ow » call.
these calls arguably not vary 1 sex other, , during mating season. example, males seem repeatedly call advertise location after finding suitable nesting site.
reproduction , life history
there sufficient gap in knowledge breeding behaviour of pavonine quetzals (and many other trogons), concerning visual , vocal displays. general trend, however, seems breeding involves courtship chasing, combination of perched , aerial visual displays, reciprocated vocal displays. these birds appear monogamous, , work excavate nest. choose nesting sites in rotting trees, old woodpecker holes, termataria, or vespiaries, , provide little no lining. reported suspected nests range 4 - 9m above ground level. confirmed reporting of pavonine quetzal nesting describes nest hollow, bare cavity deep enough hide both adults, circular wedge shaped entrance. report accounts clutch contained 2 eggs, typical of group. eggs pale blue, few light brown speckles. eggs weighed between 8.5g , 13.5g, , measured 27.6 - 28.1mm 31.5 - 32.4mm.
as distribution of roles, both sexes participated in incubation. males seem incubate during day, around 10am until sunset (near 6pm), while females incubate overnight , in morning. incubation lasts @ least 14-17 days. once eggs have hatched, adult occupation of nest decreases rapidly, male makes food deliveries young, though both parents attend young. nestlings altricial, , depend heavily on parents food, after have fledged. nestling lasts around 21 days, , fledging continue dependant 2 months. until then, parents feed them on ground or low branches. during period, chicks vulnerable predators, such raptors, snakes , squirrels.
their plumage takes few weeks grow out, starting out mixture of down-like feathers, pin feathers, , short tawny feathers, , growing out full juvenile plumage. initially, different adult counterparts, noticeable colour differences in feathers , other tissues. males, suspect young males take 3 years grow full length plumage.
