State of the Birds 2019Nearly 30% of our birds have disappeared in the last 50 years: New research published in the journal Science shows massive losses among U.S. bird populations—with steep declines in every habitat.
Migratory Birds Bumped off Schedule as Climate Change Shifts SpringClimate change is altering the delicate seasonal clock that North American migratory songbirds rely on to successfully mate and raise healthy offspring, setting in motion a domino effect that could threaten the survival of many familiar backyard bird species, new research shows.
State of the world's birds: taking the pulse of the planetState of the World’s Birds is BirdLife’s flagship science publication, providing a global overview
of the state of birds, the pressures they face and the actions underway to save them. Birds are
more popular and better studied than any other comparable group and are consequently an excellent means through which to take the pulse of the planet. So, while the report focuses on birds, its conclusions are relevant to biodiversity more generally.
eBird ScienceeBird data are a powerful resource for a wide range of scientific questions. eBird Status and Trends highlights Cornell Lab analyses of continental bird abundances, range boundaries, habitats, and trends.
Birdlife International DatazoneMost bird species are quite widespread and have large ranges. However, over 2,500 are restricted to an area smaller than 50,000 km2, and they are said to be endemic to it. BirdLife has identified regions of the world where the distributions of two or more of these restricted-range species overlap to form Endemic Bird Areas.
EBAs contain nearly all of the world's restricted-range bird species – only 7% of restricted-range species do not overlap with other such species and therefore do not occur in EBAs. The EBAs also support many of the world's more widespread bird species. Half of all restricted-range species are globally threatened or near-threatened and the other half remain forever vulnerable to the loss or degradation of habitat owing to the small size of their ranges. The majority of EBAs are also important for the conservation of restricted-range species from other animal and plant groups. For example, there is an overlap of 70% between the location of EBAs and areas which are similarly important for endemic plants globally. The unique landscapes where these species occur, amounting to just 4.5% of the earth's land surface, are high priorities for broad-scale ecosystem conservation.
Bird Life International's Datazone Climate Change MapsHere you can view maps of the projected distributions of bird species under climate change. At present, these maps are available only for bird species breeding in sub-Saharan Africa, and can be viewed by entering the English or scientific name in the box below, or by clicking on ‘Projected distribution under climate change’ in the ‘key facts box’ on the right-hand side of each species factsheet.
Species Conservation ProfilesThe PIF Watch List includes 86 species—species of highest conservation concern at the continental (range-wide) scale. Some of these species are already recognized as federally threatened or endangered in the U.S. and Canada. The Watch List fosters proactive conservation that will help recover populations of the most at-risk species and keep the remaining species from becoming endangered. | Watch List definitions explained.
