The report called “State of the Birds” took into account the approximately 800 bird species that live in the United States and analyzed their current state. Apparently, the most endangered species of birds are those who live in ocean habitats such as the Hawaii, but also those that live in grasslands and arid lands. 

 

The main problem according to the study is the loss of habitat, but also threats caused by humans such as pesticides, collisions with windows, towers and buildings. Over the past four decades, bird species that have been living on prairies, deserts and at sea, lost about 30 to 40 percent of their population. 

 

There are some habitats such as those that feature waterfowls and wetlands, that were conserved and where bird populations have regained some ground. 

 

Although there are several elements that endanger bird, in almost every case, energy production such as wind, ethanol and mountaintop coal mining, plays a role. 

 

Several environmentalist groups said that the “State of the Birds” report should trigger reaction from the Obama administration in the direction of expanding renewable energy. 

 

So far, the report caught the attention of Interior Secretary Ken Salazar, who said the "State of the Birds" should serve as a call to action and for more investment in the Fish and Wildlife Service. "If we move forward with a new ethic of conservation, we will be able to restore bird populations," Mr Salazar said in a new conference according to The New York Times.
