Lanny Chambers' First Hummingbirds
2013 Arrival is Here!
The News!
Every year, Lanny Chambers collects reports of ruby-throated hummingbirds from all over America. He generously shares his data with Journey North.

So there's one hummingbird's arrival we especially like to know about each spring: the first one Lanny gets to see in his Missouri home.

The good news:
His first sighting (male): April 15

His first sighting (female): April 29

Scientists learn a lot from records kept by citizen observers over many years. Now you be the scientist and see what you can learn.
