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.

How bird feather patterns form - According to a new study, the precise patterning of bird feathers relies on signaling through ectodysplasin (EDA) and its receptor EDAR -- the same signaling pathway known to be crucial for the formation of hair follicles, teeth and scales in fish, lizards and mammals.
Recent drought may provide a glimpse of the future for birds in the Sierra Nevada - To better understand the effects of climate change on the bird community in the Sierra Nevada region, researchers examined the impacts to birds from a recent extreme drought (2013-2016). The drought resulted in the widespread death of pine trees due to attacks by bark beetles, potentially impacting wildlife habitat. While the results were varied, researchers found that many bird species responded positively to the climate conditions associated with the drought, potentially offsetting the negative habitat impacts of the dead trees.
Origins of giant extinct New Zealand bird traced to Africa - Scientists have revealed the African origins of New Zealand's most mysterious giant flightless bird -- the now extinct adzebill -- showing that some of its closest living relatives are the pint-sized flufftails from Madagascar and Africa.
