Colombian Mountain Grackle
The Colombian mountain grackle (''Macroagelaius subalaris''), is a species of bird in the family Icteridae. Distribution and habitat It is endemic to Colombia where its natural habitat is subtropical or tropical moist montane forests. Conservation It is threatened by habitat loss and declining in numbers. It was uplisted from Near Threatened to Critically Endangered status in 2000, due to fears of a collapse of the presumably tiny population. As the species, while still severely declining, has turned out to be more widespread than believed, it was downlisted to Endangered in the 2007 IUCN Red List.See BirdLife International (2007a,b).

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
