Thousands of Miles of Migration – Some hummingbirds travel over 3,000 miles between breeding and wintering grounds.
Common Migration Routes – The Ruby-throated Hummingbird crosses the Gulf of Mexico in a nonstop 18-hour flight.
Timing Depends on Food Availability – Migration starts when natural nectar sources become scarce, usually in late summer or early fall.
– Weather Challenges – Strong winds, storms, and sudden temperature drops can threaten hummingbirds during migration. –
Energy Storage is Key – Before migration, hummingbirds double their body weight by storing fat to fuel their journey.
Artificial Feeders Help Migration – Providing nectar in the fall can support late-migrating hummingbirds as they prepare for their journey.
1. Climate Change is Affecting Routes – Rising temperatures and habitat loss are altering migration patterns and survival rates.
