Editing Trogon (section)

==Behaviour==
Trogons are generally inactive outside of infrequent feeding flights. Among birdwatchers and biologists it has been noted that "[a]part from their great beauty [they] are notorious ... for their lack of other immediately engaging qualities".<ref name ="HBW"/> Their lack of activity is possibly a defence against predation; trogons on all continents have been reported to shift about on branches to always keep their less brightly coloured backs turned towards observers, while their heads, which like owls can turn through 180 degrees, keep a watch on the watcher. Trogons have reportedly been preyed upon by hawks and predatory mammals; one report was of a [[resplendent quetzal]] taken while brooding young by a [[margay]].<ref name = "Wheelwright"/>

===Diet and feeding===
Trogons feed principally on insects, other arthropods, and fruit; to a lesser extent some small vertebrates such as lizards are taken.<ref name ="HBW"/> Among the insect prey taken one of the more important types are caterpillars; along with cuckoos, trogons are one of the few birds groups to regularly prey upon them. Some caterpillars are known to be poisonous to trogons though, like ''[[Arsenura armida]]. ''The extent to which each food type is taken varies depending on geography and species. The three African trogons are exclusively insectivorous, whereas the Asian and American genera consume varying amounts of fruit. Diet is somewhat correlated with size, with larger species feeding more on fruit and smaller species focusing on insects.<ref name=Remsen/>

Prey is almost always obtained on the wing.<ref name ="HBW"/> The most commonly employed foraging technique is a [[Hawking (birds)|sally-glean]] flight, where a trogon flies from an observation perch to a target on another branch or in foliage. Once there the birds hovers or stalls and snatches the item before returning to its perch to consume the item. This type of foraging is commonly used by some types of bird to obtain insect prey; in trogons and quetzals it is also used to pluck fruit from trees. Insect prey may also be taken on the wing, with the trogon pursuing flying insects in a similar manner to [[drongo]]s and [[Old World flycatcher]]s. Frogs, lizards and large insects on the ground may also be pounced on from the air. More rarely some trogons may shuffle along a branch to obtain insects, insect eggs and very occasionally nestling birds. [[Violaceous trogon]]s will consume wasps and wasp larvae encountered while digging nests.<ref name ="Windsor"/>

===Breeding===
[[Image:Quetzal entering nest.jpg|thumb|A male [[resplendent quetzal]] entering his nest.]]
Trogons are [[Territory (animal)|territorial]] and [[monogamy|monogamous]]. Males will respond quickly to playbacks of their calls and will repel other members of the same species and even other hole-nesting species from around their nesting sites. Males attract females by singing,<ref name ="HBW"/> and, in the case of the resplendent quetzal, undertaking display flights.<ref name=Skutch/> Some species have been observed in small flocks of 3–12 individuals prior to and sometimes during the breeding season, calling and chasing each other, but the function of these flocks is unclear.<ref>{{cite journal|last=Riehl|first=Christina|year=2008|title=Communal Calling And Prospecting By Black-Headed Trogons (''Trogon melanocephalus'')|journal=The Wilson Journal of Ornithology|volume=120|issue=2|pages=248–255 | doi= 10.1676/07-025.1|s2cid=83762310}}</ref>

Trogons are cavity [[bird nest|nesters]]. Nests are dug into rotting wood or termite nests,<ref name ="HBW"/> with one species, the [[violaceous trogon]], nesting in [[wasp]] nests.<ref name ="Windsor"/> Nest cavities can either be deep upward slanting tubes that lead to fully enclosed chambers, or much shallower open niches (from which the bird is visible). Nests are dug with the beak, incidentally giving the family its name. Nest digging may be undertaken by the male alone or by both sexes. In the case of nests dug into tree trunks, the wood must be strong enough not to collapse but soft enough to dig out. Trogons have been observed landing on dead tree trunks and slapping the wood with their tails, presumably to test the firmness.

The nests of trogons are thought to usually be unlined. Between two and four eggs are laid in a nesting attempt. These are round and generally glossy white or lightly coloured (buff, grey, blue or green), although they get increasingly dirty during [[avian incubation|incubation]]. Both parents incubate the eggs (except in the case of the [[bare-cheeked trogon]], where apparently the male takes no part),<ref name ="HBW"/> with the male taking one long incubation stint a day and the female incubating the rest of the time. Incubation seems to begin after the last egg is laid. The incubation period varies by species, usually lasting between 16–19 days. On hatching the chicks are [[altricial]], blind and naked. The chicks acquire feathers rapidly in some of the montane species, in the case of the [[mountain trogon]] in a week, but more slowly in lowland species like the [[black-headed trogon]], which may take twice as long. The nestling period varies by species and size, with smaller species generally taking 16 to 17 days to [[fledge]], whereas larger species may take as long as 30 days, although 23–25 days is more typical.
