Your Sightings!

Week #1: Seeing Hummingbirds? Let Us Know!
Please report your observations this fall as hummingbirds prepare to migrate and as they travel to their wintering grounds. With your help, we'll make a migration map to show where hummingbirds are present from August through December.

What kind of observations should you report?

  • If you see hummingbirds any time, let us know!
  • Report frequently—at least once a week—as long as hummingbirds are present.

You may report your observations of any hummingbird species. In addition to reporting weekly when hummingbirds are present, try to notice, record, and report the LAST hummingbird you see. (Date your final report as the date you saw your final hummingbird of the season.)

First to Go
The adult male ruby-throated hummingbirds are the first to migrate in the fall. Females and juveniles stay behind and migrate later.
About the Hummingbird Migration Map
Each time you report a hummingbird sighting, a dot will appear on the map. The dot means, "A hummingbird was sighted here." (So DO NOT report when you DO NOT see a hummingbird.) The dots are color-coded by date. As the season advances, the colors of the dots will change.
