Relationship with humans

Trogons and quetzals are considered to be "among the most beautiful of birds", yet they are also often reclusive and seldom seen. Little is known about much of their biology, and much of what is known about them comes from the research of neotropical species by the ornithologist Alexander Skutch. Trogons are nevertheless popular birds with birdwatchers, and there is a modest ecotourism industry in particular to view quetzals in Central America.
