Migratory birds are declining globally because of the way that humans have modified the landscape over recent decades—according to new research from the University of East Anglia.

A new study published inGlobal Ecology and Biogeographyreveals thatpopulation declineshave been greatest among species that migrate to areas with more human infrastructure—roads, buildings, power lines,wind turbines—as well as higher population densities and hunting levels.

Habitat degradation andclimate changehave also played a part in driving long-term declines.

The research team hope their work will help inform how best to target conservation efforts.
