Priotelus Temnurus

The Cuban trogon or tocororo (''Priotelus temnurus'') is a species of bird in the family Trogonidae. It is endemic to Cuba, where it is also the national bird.

Taxonomy and systematics

The Cuban trogon shares its genus with the Hispaniolan trogon (''P. roseigaster''). It has two subspecies, the nominate ''P. t. temnurus'' and ''P. t. vescus''.

In English the bird is commonly known as the Cuban trogon, while in Spanish, it is referred to as the ''tocororo''. This local name is onomatopoeic, and was derived from its repeated call, "".McCloy, M. W. D., M. Cañizares Morera, and M. Canizares (2021). Cuban Trogon (''Priotelus temnurus''), version 2.0. In Birds of the World (T. S. Schulenberg, Editor). Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.cubtro1.02 retrieved December 14, 2022 It is the national bird of Cuba.

Description

The Cuban trogon is long and weighs . Its plumage colors match those of Cuba's flag, and are the same for both sexes. The two subspecies also differ only slightly. Their beak is reddish pink with a dark culmen. Adults have a blackish face with reddish eyes, a dark metallic blue crown and nape, and a metallic green back and rump. Their cheeks, chin, and throat are white becoming clear gray on the breast and upper belly. Their lower belly and undertail coverts are red. Their tail is graduated, with the innermost feathers forming a point. The three innermost pairs of tail feathers are glossy blue-black with some bronzy highlights. The three outer pairs have blue-black bases and are mostly white beyond. The flight feathers and wing coverts are generally dark metallic green to black with a complex pattern of white spots. Juveniles have similar plumage to adults but generally are duller, with buffy gray underparts and reddish pink undertail coverts.

Distribution and habitat

The nominate subspecies of Cuban trogon is found throughout the main island of Cuba and on several large cays off the Camagüey Province shore. ''P. t. vescus'' is found only on Isla de la Juventud (Isle of Pines). The species inhabits both primary and secondary forest and also shrublands and smaller woodlands near watercourses. It favors humid shady areas within those landscapes and occurs at all elevations but is most common at higher ones.

Behavior

Movement

The Cuban trogan is mostly sedentary but makes seasonal local movements in elevation or in response to the availabilty of food. Their flight style is rather choppy and noisy.

Social behavior

The Cuban trogon is usually found in pairs though sometimes in groups of three or four. They seem "indifferent to human presence in the immediate vicinity."

Feeding

The Cuban trogon usually forages at the middle level of the forest; it takes food by sallying from a perch or by hovering at foliage or fruit. Its diet is mostly insects, fruit, and buds but it also feeds small lizards to young.

Breeding

The Cuban trogon's breeding season is mostly April to July. It nests in natural cavities or abandoned woodpecker holes, usually in trees but sometimes in arboreal termitaria. The clutch size is three or four eggs. The incubation period is about 18 days and fledging occurs about 21 days after hatch.

Vocalization

The Cuban trogon's song is "a pleasant ''toco-toco-tocoro-tocoro...'', repeated for long periods at frequent intervals." It also gives "a steady, rapid series of staccato notes" and "a low and short mournful call that makes it difficult to locate."

Status

The IUCN has assessed the Cuban trogon as being of Least Concern. It has a large range but its population size is not known and believed to be decreasing. No immediate threats have been identified. It is considered common and widespread throughout the main island of Cuba but is rare on the small offshore cays and uncommon of Isla de la Juventud. "Deforestation and habitat fragmentation pose two of the greatest anthropogenic threats to the Cuban Trogon."
