WHAT THE EVIDENCE SAYS
BirdLife International’s 2026 State of the World’s Birds synthesizes conservation-status data and scientific literature around migratory species and their flyways. The report emphasizes that migratory birds depend on linked breeding, non-breeding and stopover areas and face multiple threats distributed along those routes.
WHY IT MATTERS / OUR READ
For migratory wildlife, a protected site is only as useful as the network that connects it to the rest of the annual cycle. Flyway-scale assessment is a stronger decision frame than evaluating reserves or jurisdictions in isolation.
CAVEATS / UNCERTAINTY
This is a global NGO assessment synthesizing many underlying data sources and taxa. Threat intensity, evidence quality and conservation capacity vary substantially among flyways and species.
