Highlights:
Rubythroats Reach Canada! Rufies Taking a Turn
"A
very vocal hummingbird told me to fill my feeder!" writes
a ninth grade Journey North observer. "Just after storms
and high wind had passed through the area, we spotted our first
rubythroat," says another.
Rubythroats filled the skies this past week. After a long journey,
the first few appear to have reached Canada! Can you find the
latitude of the most northern sighting? They also landed in two
new Midwest and two New England states. How accurate were your
predictions about where rubythroats would arrive, and when? (Check
them against our 2009 arrival chart: >>)
Fickle
weather brought loads of reports on some days (April 18, for instance)
and fewer on other days (the 21st). Curious? See what you can
infer from these weather maps:

Meanwhile, the first wave of females that have already mated are
doing what comes naturally. Watch this week's slideshow to find
out how they gear up for baby hummers!

Alaskan students wonder when they'll see their
hummer >> |
While
some rufous hummingbirds buzzed all the way to Alaska, another batch
has headed east. A few even arrived in Idaho! Check out this week's
Map Puzzle to discover what awaits them there.
Remember to keep looking for your hummingbirds. When do
you usually see them? You can find your past sightings in our historic
records. Very warm temperatures in the next few days should
help hummer food sources spring forth! And light winds will make
for good flying weather.

Journal:
Imagine
Building the Perfect Nest |
Some
hummingbirds are still traveling north, but others have arrived in places
where they'll breed. Once they've mated, the females will busily begin
building nests.
How do they
prepare for this important stage of their annual cycles? Imagine you are
a hummer. Make a list of what you might need for a safe and secure nest.
How might you build one?

Many
hummers are still making the long Journey North. But the females that
already arrived and mated have big plans. Their instinct tells
them to build nests that are cushy, waterproof, and stronger than steel!
What are their secrets? Read on . . .
