The purple masked tangar ( Tangara larvata ) is a species of bird from the family of the tangar (Thraupidae) that occurs in Central and South America .
features
The purple masked tangar reaches a body length of about 12 centimeters and a weight of 17.1 to 23.9 grams. The birds are very brightly colored. They essentially show the following plumage colors:
- Head: creamy white to golden yellow
- Face mask: black, edged bluish
- Throat: reddish brown
- Chest and back: black
- Arm and hand swing as well as control springs : black, bluish to greenish border
- Arm covers , flanks and rump : turquoise, green or blue, depending on the incidence of light
- Belly: Light yellow to cream colored
Legs and feet are dark gray. Both sexes hardly differ in color. However, the females show somewhat paler colors.
Distribution, subspecies and habitat
In addition to the to the Caribbean side facing Mexico in Belize , to the east of Guatemala and in the north of Costa Rica occurring nominate Tangara larvata larvata ( Du Bus de Gisignies , 1846) are three subspecies:
- Tangara larvata centralis ( Berlepsch , 1912) - on the side of Costa Rica facing the Caribbean Sea and in western Panama
- Tangara larvata fanny ( Lafresnaye , 1847) - in eastern Panama and Colombia, as well as in Ecuador
- Tangara larvata franciscae ( PL Sclater , 1856) - on the Pacific side of Costa Rica and in the Colombian province of Veraguas .
Purple-masked tangars prefer to inhabit moist forest edges, in areas that extend from the flatlands to an altitude of 1,800 meters.
Way of life
The birds feed primarily on fruits, to a lesser extent also on arthropods . Investigations of the stomach contents showed a proportion of plant-based food averaging 68%. The purple masked tangars live in pairs or in small family groups, less often in the company of other species of tanagers. The breeding season begins differently from region to region in the months of January, February or March. Since a successful breeding rate of only 29% has been determined, it is logical that the birds create two to three broods per year. The cup-shaped nest is made from dry leaves, plant fibers and the silk of spider webs and provided with two eggs. These are whitish to pale gray in color and have brownish speckles. The breeding season is 13 to 15 days, the female breeds alone. The nestlings are provided with food by family associations and fly out after 14 to 15 days.
Hazard and protection
The purple-masked tangerine has an extensive range and is also not uncommon in protected areas and national parks. It is therefore classified by the World Conservation Organization IUCN as 
" Least Concern = not endangered". Despite the reclamation of forest areas, a significant decline in the species has not yet been identified.
