Migrations
Why Do Rufous Hummingbirds
Seem Far Ahead?
The
climate along the migration routes also plays a
big role. This map shows average coldest temperatures.
- What
are the coldest temperatures near the coast where the Rufous hummers
are migrating? Where the Ruby-throats are migrating?
- Draw
an imaginary line across the map, from west to east, starting
at the northern edge of the Rufous migration. Can you explain
why the Ruby-throats are not yet as far north as the Rufous hummers?

we think! >>
