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.
On the pacific, habitat destruction and 'invasive alien species' are the larges threats.

Higher elevation birds sport thicker down - A new study examines feathers across 249 species of Himalayan songbirds, finding that birds at higher elevations have more of fluffy down than lower elevation birds. Finding such a clear pattern across many species underscores how important feathers are to birds' ability to adapt to their environments. Furthermore, finding that birds from colder environments tend to have more down may one day help predict which birds are vulnerable to climate change simply by studying feathers.
Birds can 'read' the Earth's magnetic signature well enough to get back on course - Birdwatchers get excited when 'rare' migratory birds makes landfall having been blown beyond their normal range. But these are rare for a reason; most birds that have made the journey before are able to correct for large displacements and find their final destination. Now new research shows how birds displaced in this way are able to navigate back to their migratory route and gives us an insight into how they accomplish this feat.
Scientists identify how harmless gut bacteria 'turn bad' - An international team of scientists has determined how harmless E. coli gut bacteria in chickens can easily pick up the genes required to evolve to cause a life-threatening infection. Their study warns that such infections not only affect the poultry industry but could also potentially cross over to infect humans.
