Libro rojo de aves de Colombia
En los últimos años, se ha avanzado considerablemente en el conocimiento de la distribución de las especies de aves en Colombia; sin embargo, una muy buena parte de la información sobre la avifauna colombiana se encuentra dispersa en libros, artículos científicos, informes y literatura gris, observaciones personales no publicadas, así como en colecciones públicas y privadas. Estos registros, junto con las capas de información climática, fueron la base con la cual se desarrollaron los modelos de distribución de las especies en los cuales se apoya esta obra.
Who's Who Among Hispanic Americans

Why Birds Matter
"Explore[s] the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions-- all seen through the lens of human well-being. ... The contributors show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies."--Back cover.
Parrots
This is the first book created primarily for the field identification of parrots, one of the most familiar and colorful groups of birds. From the mighty. macaws to the diminutive pygmy parrots, the 350 species of parrots include cockatoos, parakeets, lovebirds, and Budgerigar. Most are brightly colored or even gaudy, but a few are drab, and some are nocturnal and flightess. Parrots, found throughout most of the warmer regions of the world, occur in greatest numbers in Australasian and South America. This book includes 88 superb color illustrations of every species and most identifiable subspecies of parrot, as well as range maps of their locations. It offers many firsthand insights into the ecology of each species, vocalizations, life cycle characteristics, and geographical variation. It also provides up-to-date information on the conservation status of those species of parrots that are threatened or endangered.
Endemic Bird Areas of the World
More than a quarter of bird species are concentrated in areas that together make up just one per cent of the earth's land surface. These restricted range species include almost three-quarters of all threatened birds. BirdLife International has identified 218 Endemic Bird Areas (EBAs), which hold at least two restricted range species, although some support more than 60. EBAs provide a reasonable overlap with the biodiversity hotspots identified by other conservation organisations, and are a focus for conservation action. At the heart of this book are descriptions of all 218 EBAs, including key habitats, major threats and conservation initiatives and a detailed map. Tables list the restricted-...
