Cornell Chronicle – “A blueprint for conserving enough habitat to protect the populations of almost one-third of the warblers, orioles, tanagers and other birds that migrate among the Americas throughout the year is detailed in research published April 15 in Nature Communications. An international team of scientists used eBird, the Cornell Lab of Ornithology’s global citizen science database, to calculate how to sufficiently conserve habitat across the Western Hemisphere for all the habitats these birds use throughout their annual cycle of breeding, migration and overwintering. The study provides planners with guidance on the locations and amounts of land that must be conserved for 30% of the global populations for each of 117 bird species that migrate to the Neotropics (Central and South America, the Caribbean and southern North America). More than one-third of Neotropical migratory birds are suffering population declines, yet a 2015 global assessment found that only 9% of migratory bird species have adequate habitat protection across their yearly ranges to protect their populations. Conservation of migratory birds has historically been difficult, partly because they require habitat across continents and conservation efforts have been challenged by limited knowledge of their abundance and distribution over their vast ranges and throughout the year…”
