Highlights:
Welcoming the Waves
"Our
little jewels are back," writes one observer. Warm southerly
winds paved the way this week for a flood of ruby-throated hummingbirds:
66 new reports! Can you find the two new
states they've moved into? How does this compare with your predictions
— or with last year's migration? (Look at today's
Rubythroat Map Questions handout.)

Out West, a big batch of rufous hummingbirds are gathered in
Oregon and Washington. A careful observer has one explanation: "The
red-flowering currant (one of their earliest spring food sources)
is just about to open its first flowers."
They may be feeding on blooming wildflowers, but how did they manage
to get so far ahead of the rubythroats? Today's slideshow will give
you some clues.
"I
saw my first male. He comes every year. Females follow," writes
one hummingbird lover. So far, most observers
have spotted only male birds of both species.

It
looks like it will be a colder, rainy weekend in rubythroat country.
Will they rush northward ahead of the front or just hunker down?
Keep your eyes peeled and stay tuned for next week's update!
In the meantime, what can you learn about this incredible migration
from other Journey north observers?

Why Do Rufous Hummingbirds Seem Far Ahead? >>

Look
at both of this week's migration maps, above. How can rufous hummingbirds
be in Canada already, when rubythroats are still gathered in the southern
United States? Are the Rufous hummers faster or more eager? Is this just
an unusual year? How would you explain this?

Hungry
hummingbirds are headed your way! Even if you live in an area where they
don't nest, some might stop by on their way north. Will they be able to
find what they need to survive in your backyard or schoolyard? Let's explore!
