Emerald Toucanets, Aulacorhynchus prasinus are found abundantly in Central and South America, mostly along the eastern coast. They are sparse in the eastern-central parts of Mexico and exist more densely in the southern mountainous parts down through Costa Rica and Panama into the northernmost part of Venezuela.

Their native habitats are in Mexico, Costa Rica, and Panama in the higher elevation cloud forests. They have recently expanded their range into lower elevation rain forest.

Emerald Toucanets will make aulacorhynchuus home at elevations from m up to m 3, feet – 10, feet. They migrate vertically from lower elevation to higher elevation. The male and female are monomorphic alike in color, but dimorphic different in size. The smallest of the toucans, Emerald Toucanets are commonly 30 cm.

The male will weigh in at about pradinus. Adults have colorfull beaks, with a definite outline of white on both; the top one colored yellow, and the bottom one colored black or dark red depending on the subspecies.

Their feather coloration, dominantly green with highlights of whites, grays, and reddish browns, makes them blend in with the colors of the trees in which they dwell. CampbellDunningPerrinsTerres Mating season is typically March through July depending on the weather, as inclement weather will harm the eggs or the female during incubation.

This usually begins after the pair has worked at preparing a nest. Three or four white eggs are typically found in a tree-hole nest located aulacorhynchks 2 and 30 meters 7 feet – 90 feet above ground. Each egg has an incubation period of about 16 days.

Both parents participate in the incubation before hatching, and in the nesting and feeding after; but are never in the nest at the same time. Prsainus parents keep a clean nest for their altricial not well developed young.

The chicks have no eyesight the first 16 days, and though their eyes may no longer be tightly closed at about 25 days, they remain cloudy until about 27 days. Their feathers are not at all apparent the first 20 days. At about 35 days, except for having only pink skin around their eyes and the absence of the white line on their mandibles, they appear to have full plumage–green, like the adult.

They take flight as early as 40 days, at which time the feedings provided by the parents begin to decrease until such time as the young do not return to the nest at all; at about 43 days. CampbellSkutch Emerald Toucanets search for food in pairs or small flocks of up to about eight birds.

They are very active birds covering large amounts of territory on a daily basis.

They roost in trees, perched on aulacorhynchhus. A nest prssinus used only for incubation and raising the brood. SkutchTerresToucans Emerald Toucanets are omnivorous, eating lizards and the eggs or nestlings of other birds when possible, though insects and fruits are the largest part of their diet.

A Bat Falcon–once observed by a boy who helped Alexander Skutch find nests at Montana Azul–was the only predator aulaforhynchus adult Emerald Toucanets, cited within. It is presumed snakes and other arboreal animals are also a threat, primarily to eggs or aulcaorhynchus offspring.

Emerald Toucanets have been identified as a seed disperser for several rainforest trees. Studies indicate that the germination rate of seeds of these trees is higher following the seeds passing through the digestive tract of the bird.

Emerald Toucanets were not found in any of these endangered species databases. However, the importance being placed on the coffee market may someday have a negative effect of survival for this species. In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.

Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Aulacorhyjchus and climbing plants are also abundant. Aullacorhynchus is typically not limiting, but may be somewhat seasonal. Accessed October 14, at http: A Field Guide to Mexican Birds. Birds of Tropical America. University of Texas Press.

IUCN Red List of Threatened Species

Mating System monogamous Three or four white eggs are typically found in a tree-hole nest located between 2 and 30 meters 7 feet – 90 feet above ground. Typically the Emerald Toucanet is considered to be a secondary cavity nester, appropriating previously excavated holes in trees from smaller species.

This nest hole is then enlarged just enough for the adult Emerald Toucanet to get inside. The male seems to be the relief parent in nesting activities, giving the female short to extended breaks during the process of preparing the nest, cleaning the nest, and foraging and aulacorjynchus the brood.

While the brood is present only the female will stay throughout the night. The male relief comes throughout the day.
