description
Appearance
Adult rose- bellied finches reach a length of 13.5 to 14.5 centimeters and a weight of 19.5 to 20.5 grams. There is a clear sexual dimorphism between the sexes . In the males, the head, throat, cheeks and neck have a strong blue color. The back, the shoulders, the wing feathers and the control feathers are colored a little lighter blue. The breast plumage is blue and has a reddish marbling, the belly has a salmon-red color. The females are colored gray-brown on the head and top. The wing feathers are framed in matt brown, some in light brown. Throat, chest and stomach are colored light reddish brown. In both sexes, the upper bill is blackish, the lower bill pale gray-blue. The feet are a lead gray color. The eye ring is white and divided into two semicircles, the iris is black-brown.
Vocalizations
The song of the males of the rose-bellied finch consists of a sequence of slightly blurred and wavy notes that contain the tones “plik” or “plek”.
distribution and habitat
The range of the rose-bellied finch extends over an area from the east of the Mexican state Oaxaca to the west of Chiapas . It lives in dry thorn and deciduous forests, sometimes also in swampy terrain at altitudes between 180 and 800 meters.
Way of life
There is currently no information on the diet of the birds. Little is known about the breeding behavior. The cup-shaped nest is made from dried leaves and crushed bark and padded with fine grass. The outside diameter is 10 to 12, the inside diameter 4.0 to 5.5 centimeters. Three to four eggs are laid, which are whitish or light blue in color and have a few small red-brown spots.
Hazard and protection
The rose-bellied finch is classified by the IUCN as 
" Near Threatened " due to its small distribution area and the partial loss of its habitat . The total number of individuals is estimated to be less than 50,000 animals.
Etymology and history of research
George Newbold Lawrence described the rose- bellied finch as Cyanospiza rositae . He got the type specimen with a description from Adrien Louis Jean François Sumichrast (1829–1882) and came from Tehuantepec . As early as 1816, Louis Pierre Vieillot had introduced the new genus Passerina for the indigo finch ( Passerina cyanea Linnaeus , 1766), which was later assigned to the rose-bellied finch. "Passerinus" is the Latin word for "similar to Sperings". The specific epithet »rositae« is dedicated to Rosita Sumichrast, the wife of the discoverer.
