Hummingbirds are remarkable long-distance migrants with high energy requirements. Understanding how to support them in gardens provides direct welfare benefit.
Supporting hummingbirds through gardens is one of the most direct welfare interventions available to anyone with outdoor space. A garden with clean nectar feeders and appropriate flowers provides refuelling resources that may be critical to individual migration success. Hummingbirds that fail to accumulate sufficient fat stores before the Gulf crossing face death from exhaustion at sea — the welfare stakes of adequate refuelling are existential for individual birds. The welfare responsibility of maintaining feeders also creates obligations: unclean feeders with fermented nectar cause serious harm and require regular cleaning (every 2-3 days in summer). Window strikes kill hummingbirds — applying bird-safe film or window markers prevents deaths that feeders attract birds to risk.
