Spring 2010 Migration of Ruby-throated Hummingbirds
Are they in your area yet?
Should they be in your area any time soon? It looks like in the past few previous years that March 26th was the earliest in my area, but most of the time it is sometime in April.
There are also links at the link below to see how they migrated in past years, which is interesting. You can also use a form at the link below to report the first sighting in your area.
