USA: First Annual State of the Birds Report
“Citizen science plays a critical role in monitoring and understanding the threats to these birds and their habitats, and only citizen involvement can help address them,” said National Audubon Society’s Bird Conservation Director, Greg Butcher. “Conservation action can only make a real difference when concerned people support the kind of vital habitat restoration and protection measures this report explores.”
Birds are beautiful, as well as economically important and a priceless part of America’s natural heritage. Birds are also highly sensitive to environmental pollution and climate change, making them critical indicators of the health of the environment on which we all depend.

“This report is a clarion call to action,” said Salazar at a press conference, noting that some of the major factors threatening birds include growing human populations, climate change and water quality. The report synthesizes more than 40 years of data from three long-running bird censuses conducted by thousands of citizen scientists and professional biologists through programs such as the National Audubon Society’s annual Christmas Bird Count.

Secretary of the Interior Ken Salazar today released the first ever
comprehensive report on bird populations in the United States, showing
that nearly a third of the nation’s 800 bird species are endangered,
threatened or in significant decline due to habitat loss, invasive
species, and other threats.
At the same time, the report highlights examples, including many species of waterfowl, where habitat restoration and conservation have reversed previous declines, offering hope that it is not too late to take action to save declining populations.

The United States is home to a tremendous diversity of native birds,
with more than 800 species inhabiting terrestrial, coastal, and ocean
habitats, including Hawaii. Among these species, 67 are federally
listed as endangered or threatened. An additional 184 are species of
conservation concern because of their small distribution, high
threats, or declining populations.
Successful conservation requires
information about the population status of every species to ensure the
survival of endangered birds and to manage common species so they
never become threatened. This report presents a new synthesis of major
bird-monitoring databases, including data from thousands of citizen
scientists and professional biologists. We used data from three
continent-wide monitoring programs to create bird population
indicators for major U.S. habitats, reflecting the health of these
habitats and the environmental services they provide. These habitat
indicators are based

Hello. my question is, when birds give birth how long does it take for the chicks to grow then fly away. I believe I’m asking the right question, because I live in howard county maryland and there is a nest within my balcony and the upstairs 1. The grown birds come and feed the chicks everyday and they have been there about 2-3 wks now.
