Track the Migration
Join us as we track the migration of hummingbirds traveling to their wintering grounds. Citizen scientists across North America are observing seasonal changes and reporting hummingbird sightings.
About Fall Hummingbird Migration
Fueled by the nectar, hummingbirds double their weight as they prepare to fly hundreds or even thousands of miles. Males leave first, as early as mid-July. Females follow, and then the young who migrate for the first time all alone.
- Weekly migration news: August 24 - October 26
Fall Migration 2020
Report at least once per week as long as hummingbirds are present. Do not report when you no longer see them.
