![]() ![]() The earliest formally described fossil specimen is a cranium from the Fur Formation Lower Eocene in Denmark (54 mya). The unique arrangement of the toes on the foot (see morphology and flight) has led many to consider the trogons to have no close relatives to place them in their own order, possibly with the similarly atypical mousebirds as their closest relatives. More recent morphological and molecular evidence has suggested a relationship with the Coliiformes. ![]() A variety of relations have been suggested, including the parrots, cuckoos, toucans, jacamars and puffbirds, rollers, owls and nightjars. The position of the trogons within the class Aves has been a long-standing mystery. They nest in holes dug into trees or termite nests, laying 2–4 white or pastel-coloured eggs. They are the only type of animal with a heterodactyl toe arrangement. Trogons have soft, often colourful, feathers with distinctive male and female plumage. Trogons are generally not migratory, although some species undertake partial local movements. Although their flight is fast, they are reluctant to fly any distance. They feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits. The genera Harpactes and Apalharpactes, containing twelve species, are found in southeast Asia. The genus Apaloderma contains the three African species. The greatest diversity is in the Neotropics, where four genera, containing 24 species, occur. Trogons are residents of tropical forests worldwide. The word trogon is Greek for "nibbling" and refers to the fact that these birds gnaw holes in trees to make their nests. They might constitute a member of the basal radiation of the order Coraciiformes and order Passeriformes or be closely related to mousebirds and owls. ![]() The fossil record of the trogons dates back 49 million years to the Early Eocene. The family Trogonidae contains 46 species in seven genera. The trogons and quetzals are birds in the order Trogoniformes / t r oʊ ˈ ɡ ɒ n ɪ f ɔːr m iː z/ which contains only one family, the Trogonidae. Red-naped trogon song, recorded near Bangar, Brunei The natural, healthy appearance of the Tioga River will ultimately be restored.A male red-headed trogon in Khao Yai National Park, Thailand As the AMD pollution is reduced, the natural action of the river flow will, over time, clean the riverbed and reestablish the habitat. These deposits have destroyed the habitat for macroinvertebrates, which are bugs that can be seen with the naked eye, that would normally make their homes in rocks, leaves, and sediment of the riverbed. Deposits of iron, manganese, and aluminum, have been accumulating in the River corridor for many years. Improve, over time, the health and appearance of the River corridor through the reduction/elimination of mineral deposits. ![]() Improve the water quality impounded in Tioga Lake so that the US Army Corps of Engineers can change their operating procedures to impound water for water storage and low flow periods.Improve water quality in the mainstem of the Tioga River so that it once again supports aquatic life and stocked trout, creating recreational fishing opportunities. ![]()
