Birds

There are approximately 400 endangered bird species in the world today. The bird habitat is getting smaller, despite increased government protection . Many bird species are reaching dangerously low numbers. Scores of bird species have become extinct in the past, far more than the current amount of existing bird species.

Through habitat destruction, the introduction of non-native species, and deliberate hunting, we endanger many species. In the last 280 years, 42 species and 44 subspecies of birds are known to have become extinct.

The majority of Asian birds lives in forrests. These forrests are threatened by conversion to other land-uses and overexploitation. Therefor the birds are threatened by the same dangers.
Carrabean birds are threatened by erosion of pristine habitats and illegal trade of the birds.
Hunting and economic development are the majority of the causes that lead to death of birds in Europe.

Unique study shows how bats maneuver - For the first time, researchers have succeeded in directly measuring the aerodynamics of flying animals as they maneuver in the air. Previously, the upstroke of the wings was considered relatively insignificant compared to the powerful downstroke but, in a new study, biologists have observed that it is on the upstroke of the wings that bats often turn.
Species' longevity depends on brain cell numbers - Scientists have thought that the main determinant of maximal longevity in warm-blooded animals -- which varies from as little as 2 to as many as 211 years -- is a species' metabolic rate, which is inversely related to body size. It follows that at 2 years of life, small animals with high metabolic rates are already old, but large animals with low metabolic rates are still young.
Goffin's cockatoos can create and manipulate novel tools - Goffin's cockatoos can tear cardboard into long strips as tools to reach food -- but fail to adjust strip width to fit through narrow openings, according to a new study.
