Highlights: Nearing the Home Stretch — and Nests
"I heard a familiar buzzing. It was the wings of the hummingbird as he hovered close to my head," writes one observer. "It's always exciting when the first on arrives!" say sixth graders in Budd Lake, New Jersey. Reports pored in this past week as a big band of hummingbirds pushed into the northern part of the States and further into Canada. Look at the animation to see what has changed. >>

Did you see the most northern rubythroat report? Look at the map and find the latitude of the sighting. Then look at our distribution map (above). What do you notice?

Why were so many rubythroat sightings reported this past two weeks? Perhaps good flying weather or a high number of observers played a role. More important, most of these mini migrants have left their wintering grounds and are following the instinct to race north and breed. As they do, they find an explosion of blooming plants, hatching insects, and full feeders stretching from border to border — and beyond.

Be sure to add to your Migration Route Prediction Charts. Rubythroats moved into South Dakota, New Brunswick, and Quebec last week. Rufous hummers landed in Montana. Also, when you first spot a hummer, please report it. Your sightings help us all learn more about hummingbirds and what affects their timing.

Rufous hummingbirds continue to push into the mountains to dine on wildflowers. Word has it that one newly arrived rufous was banded 2,100 miles away near New Orleans! We'll share the exciting story and photos next week.
Meanwhile, let's peek inside some nests.

Year-end Evaluation: Please Share Your Thoughts! >>
Will you take a few minutes to complete our Year-end Evaluation? (We'll still send hummer reports through May.)

With your help, we can we document Journey North's reach, impact, and value. We need comments like yours to keep the program going and growing. Thank you! >>
