"According
to a chart we've
been keeping for several years, we should be starting to see many
different kinds of spring birds now. We aren't seeing hide nor feather
of any of them!" writes Joyanne Hamilton, teacher at Innoko
River School.

Try
This! Shageluk's Weather and Migrants: Your Prediction
- Find
Shageluk on the NOP map (right) and then on a map of Alaska
in the atlas. Use the atlas to find McGrath, AK. Remember what
Ms. Hamilton said: "When
the weather is bad between McGrath (in the interior) and us
(on
the western
interior, closer to the coast), we won't see any migrants until
the weather clears." How
does the two-week forecast look? Now see #2, next:
- Click
on this Web page to see the weather forecast for the
next two weeks in Shageluk. Notice that the page includes a
map that shows the temperature anomaly. Look
up the word anomaly.
- In
2005 the first Robin seen was on April 10. Study the school's
chart to
look for any patterns for all the bird sightings. Consider
the two-week weather forecast. Then make a prediction
for
when the first robin will be seen in 2006. (NOTE: The dates
in Journey North's records for Shageluk vary slightly from
this chart. How do you suppose the school's data and the data
in our data bank could be different?)
- The
first
Bald Eagle sighting is 10 days earlier than last year. Does
that fit any patterns that you see in the data? Would you
consider the sighting to be an anomaly, or within normal?
Defend your answer.
It
Depends on the Weather: A Look Back
"We
here in Shageluk are gifted with a series of spring birds on
their migration to western Alaska! Our birds in Shageluk
mostly come from east to west as the birds fly into Canada and
then
into Alaska--up the continent, and on the northward migration
flyway path for most of the North American birds. When the weather
is bad between McGrath (in the interior) and us (on the western
interior, closer to the coast), we won't see any migrants
until the weather clears." Ms. Hamilton remembers back to
nine years ago when "flock after flock after flock of every
bird imaginable came soaring over and passing by—going
directly east to west!"
