Hummingbirds face declining habitat from urbanisation, pesticide use, and climate-driven shifts in flower blooming times, but gardens and urban green spaces can provide meaningful refuge.
Hummingbirds face welfare challenges from pesticide exposure that reduces their insect food supply, habitat loss reducing native flower availability, and feeder-transmitted disease when feeders are not adequately maintained. Window strikes cause significant mortality in urban areas. Climate phenological mismatches leave migrating hummingbirds arriving before nectar flowers are available. Garden actions including planting native flowering species, eliminating pesticides, and maintaining clean feeders provide measurable welfare benefits at scale.
