Climate crisis driving sharp decline in migratory bird populations
A British Trust for Ornithology review finds over half of global migratory species are suffering major declines, with climate extremes and habitat loss among key drivers.
What to know
- Over half of migratory bird species tracked by the British Trust for Ornithology are experiencing major population declines, particularly those using the African-Eurasian flyway.
- Climate change—both gradual warming and intensifying extreme weather events—is the primary driver among multiple threats including habitat loss, disease, and pesticide use.
- Conservation efforts must address threats across entire lifecycles and international migration routes, with habitat preservation a critical focus.
Climate change is a critical threat to migratory species that requires immediate attention and conservation action.

“It is not just the long-term effects of major shifts that affect migratory birds, but also the extreme weather events that have become far more frequent and intense.”

"Among many and complex causes of these declines, including habitat loss, disease and pesticide use, one stands out: the climate crisis."
