Migratory songbirds travel thousands of miles between breeding and wintering grounds, requiring conservation action across hemispheres to protect populations that are declining across North America.
Songbird conservation requires thinking at landscape and hemispheric scales that individual welfare concern rarely encompasses. A warbler breeding in a New England forest faces threats on its wintering grounds in a Costa Rican plantation and at stopover sites along its migration route — none of which are within the concern of local conservation efforts focused only on breeding habitat. The welfare of individual migratory birds depends on conditions across thousands of miles. Consumer choices about certified coffee and chocolate directly fund the wintering ground habitat that determines whether birds can recover their condition after breeding and survive to migrate again.
