Abstract
Las aves que habitan en la cuenca del Titicaca tienen una amplia distribución
que comprende, cordilleras, pajonales de puna y el Lago Titicaca reconocido
por la Convención Ramsar como Humedal de Importancia Internacional. En
el presente trabajo se han registrado 135 especies comprendidas en 17
órdenes 33 familias y 83 géneros. Con respecto a la estacionalidad, 95
especies son residentes y 40 provienen de otras latitudes, de las cuales 17
especies son migratorias neárticas, 10 especies migratorias australes, y 13
especies realizan migraciones verticales desde los Andes peruanos hacia la
región costera. Por el tiempo que pasan en la mayor parte de los ambientes,
81 especies son terrestres, 45 acuáticas y 9 en vuelo. Los resultados
obtenidos han determinado que las especies de aves residentes pasan todo el
año en la cuenca del Titicaca: las migratorias nearticas desde setiembre a
marzo, las migratorias australes entre abril a agosto y las que realizan
migraciones altitudinales hacia la región costera, de mayo a agosto.
which includes, mountain ranges and “pajonales of puna”. The Titicaca lake is recognized by the Ramsar Convention as Wetland of International Importance. In the present work, 135 species comprised in 17 orders, 33 families and 83 genders have been registered. With regard to seasonality, 95 species are residents and 40 are from other latitudes, of which 17 species are Nearctic migrants, 10 migratory species come from the Austral Region, and 13 species make vertical migrations from The Peruvian Andes to the coastal region. For the time they spend in most environments, 81 species are terrestrial, 45 aquatic and 9 in flight. Therefore, the results obtained have determined that the species of resident birds spend all year in the Titicaca basin: the neartic migrants from September to March, the austral migratory birds between April and August and those that make altitudinal migrations to the coastal region, from May to August.
