Many bird species could lose between 78 and 85 percent of their existing habitat
Birds and reptiles in the Southwest that live in fragmented habitat will be hit hardest by global warming in the decades ahead, according to a new study by scientists with the U.S. Geological Survey and the Northern Arizona University.
The researchers took a close look at about 30 different animals, including well-known species such as the Gila monster, horned lizard, chuckwalla, Sonoran desert tortoise, pinyon jay, pygmy nuthatch, sage thrasher and black-throated sparrow.
Climate change may bolster spotted owl survival in the future
Northern spotted owl populations continue to decline across the Pacific Northwest, researchers said in a new study showing that competition from barred owls, along with habitat destruction and climate change are all factors in population trends.
Decades of poaching, habitat destruction take toll on birds
Two rare bird species in Central and South America will get protection under the Endangered Species Act, the U.S. Fish and Wildlife Service announced last week. Under the listing, military and great green macaws can’t be imported into, or exported out of, the U.S.
Steep downward trend poses threats to marine ecosystems
FRISCO — Researchers with the University of British Columbia say that global seabird populations — including penguins, albatrosses, petrels and pelicans — have declined by 70 percent since the 1950s — a clear sign that marine ecosystems are in trouble.
The findings are based on an analysis of more than 500 seabird populations , representing about 19 per cent of the global seabird population. The 70 percent decline is equivalent to the loss of about 230 million birds in 60 years, said Michelle Paleczny, a UBC master’s student and researcher with the Sea Around Us project.
Some Sonoran Desert species skip breeding entirely during extreme drought
FRISCO — Drought-driven delayed nesting by some southwestern bird species may lead to crashing populations, scientists said in a new study that looked closely at Sonoran Desert bird species, such as Black-tailed Gnatcatchers and Verdins.
The research suggests drought conditions are delaying nesting by two weeks or more for some species. Despite recent rainfall, drought conditions persist in much of the Southwest, making life tough even for species adapted to a dry environment.
‘It is clear that the way we are managing the environment is unsustainable for many of our most familiar species’
Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, according to a new study from the University of Exeter (UK).
