Wild Migratory Bird Stopover Habitat

Migratory birds depend on networks of stopover habitats along flyways to rest and refuel during epic journeys — loss or degradation of these sites causes exhaustion, starvation, and mortality affecting billions of birds annually.

Key Facts

An estimated 5 billion birds migrate across North America twice each year, with similar numbers across other major flyways
Stopover sites provide essential food and rest — migrants may double their body weight at key sites to fuel further travel
Wetland loss has eliminated 35% of global wetland habitat since 1970, devastating waterbird stopover networks
Light pollution causes millions of bird collisions with buildings annually and disrupts migratory navigation
Climate change is shifting the timing of migration, creating mismatches between arrival and peak food availability at stopovers
The Yellow Sea — a critical stopover for East Asian flyway shorebirds — has lost over 65% of its intertidal habitat to land reclamation
Pesticides at stopover sites can cause acute poisoning of migrants depleted by long flights and highly vulnerable to toxins
Protected area networks along flyways, like the East Atlantic Flyway network, coordinate conservation across national boundaries

Welfare Considerations

The welfare of migratory birds at stopover sites is shaped by the quality and availability of habitat at critical junctures in journeys that can span thousands of kilometres. A bird arriving at a degraded or absent stopover site in a state of energy depletion faces starvation, exposure, and increased predation risk — states of acute suffering that can extend over hours or days before death. The scale of impact is enormous: billions of individual welfare experiences are shaped by the health of stopover habitat networks. Conservation investments in stopover sites deliver both species-level biodiversity benefits and individual welfare outcomes — healthy stopover networks mean fewer birds dying from exhaustion and starvation.

What You Can Do

Support conservation of wetlands, coastal habitats, and other critical stopover sites along major flyways
Make your garden or green space bird-friendly with native plantings that provide food during migration periods
Reduce light pollution at home and advocate for dark-sky policies to protect migratory birds from collision and disorientation
Donate to flyway conservation organisations working across national boundaries to protect connected habitat networks
