The US bird is experiencing dangerous decline due to factors such as population, housing loss and climate change, according to a new report, which is identifying 112 species, reaching “tipping points”, including 42 low numbers and 42 with trends at the bottom.
Even the duck population, which has been considered a conservation success story, is running downwards in recent years, although they are still more than the 1970 levels, according to the report, has been released on Thursday by a group of science and protection organizations.
In the report, 718 species were observed using population data such as Ebard Status and Trends Project of Ornithology, Breed Bird Survey of US Geological Survey and Cornel Lab of National Audbon Society Avian Avian Counts.
One of the about three bird species (229 species) in the US requires immediate conservation, and these species represent major houses and systems in the US and include species that we consider to be normal and abundant for a long time, “the Center for Avian Population of Ornithology, said Amanda Roadwell.
The report identifies species that have lost more than 50% of their number within the previous half century. Among them, it lishes 33 “yellow alert” species with loss of long -term population, but relatively stable recent trends, 37 with long -term damage with 37 “orange alert” species that intensified within the last decade and 42 “red alert” species dangerously and a dangerous decline with species.
Some of these red alert species include motten duck, allen’s Humingbird, Yellow-Bill Loon, Red-Pied Commerant, Greater SEZ-Grause, Florida Scrub J, Sparrow, Sparrow, Saltmarsha Sparrow, Mountain Plover, Havin Petrell, Bacinel’s Thrush, Cassibard, Pink-Faster, Pink-Ford, Pink-Ford, Pink-Fais, Pink-Forbord were included.
Some of these birds already have security under the US endangered species Act.
“Loss and decline of habitat remain the most important contributor for the decline of birds and other species,” said Rhodwaved.
Other factors quoted in population fall included climate change, aggressive species, pollution and bird collisions, for example with wind turbine blades and buildings.
The report found that the avian population is decreasing in almost every habitat, including grasslands and dry areas. Shorebirds are groups with the most “tipping point” species on 19.

“This represents a huge biodiversity loss,” said Michael Parr, president of the American Bird Conservancy.
“The only bright place is water birds such as heron and the elite that show the growth,” Parr said.
Some examples of normal birds now include chimney swift, wood thrush, grasshopper sparrow, Eastern Medovlark, Common Grackle, Barn Swallo, Blackpol Warbaler, Herring Gul and Bobolink.
Marshall Johnson, Chief Conservation Officer of the National Audbone Society, said, “We have brought back the bird population from the first and we can do it again.”
“Not only birds play an important role in our ecosystem, they are also incredibly important parts of our life,” he said. “Protecting birds is good for environment, local economies, and it is good for people.”
