Think
and Discuss!
This map shows how much colder or warmer last week's
temperatures were than normal temperatures during the second week
in March.
- Look
at the part of the country where the leading ruby-throated hummingbirds
are now migrating. How would you describe the temperatures there?
- Look
at the part of the country where the leading rufous hummingbirds
are migrating. How would you describe the temperatures there?
- How
do you think each of the migrations could be affected? Explain
your answer. (Hint: Think about what hummers need to survive.)
