eBird Science: Prioritizing dynamic conservation for migratory birds

What if, instead of buying habitat, conservationists could rent it when and where migratory birds need it most? eBird data is playing a critical role in helping make this a reality, enabling new cost-effective approaches to complementing protected areas with ‘pop-up’ wetlands. This work has just been published in Science Advances, “Dynamic conservation for migratory species.” To pinpoint where and when migrating shorebirds most need habitats in California’s Central Valley, scientists at The Nature Conservancy, Cornell Lab of Ornithology and Point Blue Conservation Science used models based on eBird data on shorebirds and NASA satellite data on surface pattern of wetlands and flooded agricultural fields. 

Eastern North American forest birds most threatened on wintering grounds

Over the past few millennia, human-caused habitat change has had one of the most profound effects on bird populations globally, especially since industrialization in the 1800s. Looking forward, we can expect human-caused habitat loss to represent the greatest threat to many North American breeding birds. The problem will be most severe on their wintering grounds, according to a new study published today in the journal Global Change Biology by a international research team including representatives from the Cornell Lab, Environment and Climate Change Canada, and VU University Amsterdam. By the end of this century, the study’s authors say predicted changes in rainfall and temperature will compound the problem for birds that breed in eastern North America and winter in Central America.
