Hermit thrushes and other neotropical migratory songbirds face welfare challenges from habitat loss on both breeding and wintering grounds.
Migratory songbirds face welfare challenges across the full extent of their annual range. Collisions with buildings, towers, and power lines kill an estimated 1 billion birds per year in North America alone. Habitat loss forces birds into suboptimal areas. Pesticide reduction of insect prey causes food insecurity during breeding. Spring migration timing increasingly mismatches with peak insect emergence due to climate change, creating periods of food scarcity for arriving birds.
