Update: May 10, 2007 Name
at the band of dots (dark orange-red) that show hummer reports from
the last 2 weeks. Within what major lines of latitude do most of
the reports fall?
are about 69 miles between each degree of latitude. Can you calculate
about how far the Rubythroat migration traveled in the past 2 weeks?
In the past week?
say that on average, the Rubythroat migration travels at about
20 miles per day (or 280 miles per week). How does this compare
to your answer?
factors could affect the rate the migration moves ahead in any week?
