features

The red-eared macaw reaches a body length of 60 cm and a weight of about 500 g. The coloring is predominantly olive green , the rump is olive . The forehead, crown of the head, ear covers and shoulder patch are orange-red, as are the under wing coverts, the flanks and the plumage on the legs. The wings are mostly blue. The tail feathers are olive colored and blue at the top and olive-yellow at the bottom. Compared to other species, the featherless part of the face is quite small and pink-white in color, the iris is orange. The bill and legs are gray-black.

The proportion of red on the head, ear-covers and wings of the young birds is lower. Their coloring is duller with less blue on the inner control springs.

distribution and habitat

Distribution area of ​​the red-eared macaw

The red-eared macaw occurs endemically in a very small range on the eastern slope of the Andes in south-central Bolivia. The habitat of the red-eared macaw is between 1100 and 2500 m, locally up to 3000  m in the inter-Andean dry valleys of Bolivia. In this area there is a steppe and semi-desert climate with thorn bushes, cacti and a few trees.

Way of life

The diet consists of fruits and seeds. Red-eared Macaws also eat crops, especially peanuts and unripe maize, which is why it is locally considered a pest in Bolivia. The sleeping and nesting places are located on undisturbed river cliffs. Oviposition was reported from November and, in exceptional cases, into April. One or two, and occasionally three, young are raised. The parents and young animals remain in the breeding grounds from the end of March to the beginning of April.

Hazard and protection

The red-eared macaw population is very small and continues to decline. The International Union for Conservation of Nature and Natural Resources (IUCN) classifies the species as Endangered (EN). It is listed in the Washington Convention on the Protection of Species (CITES) in Appendix I and in EC Regulation 709/2010 [EC] in Appendix A and is strictly protected according to the Federal Nature Conservation Act [BG] (Status :: s).

Etymology and history of research

Frédéric de Lafresnaye described the red -eared macaw under the name Ara rubro-genys . He had the type specimen from the Muséum national d'histoire naturelle and it came from Bolivia , the place where Alcide Dessalines d'Orbigny had collected it. The word "Ara" comes from an onomatopoeia from the Tupi language for the sounds of the New World parrots . Bernard Germain Lacépède introduced the generic name in 1799. The specific epithet »rubrogenys« is a Latin word formation from »ruber« for »red« and »gena« or Greek »genys, genyos γενυς, γενυος « for »cheek, cheek«.
