Rufous
Hummingbirds Gone Astray?
Making
Sense of Unsual Sightings
(Back
to Lesson)
Overview:
In
Journey North, unusual sightings are common — a Monarch spotted
in England or a hummingbird sighted too "early" in the season,
for instance. This lesson asks students to think like scientists who
ask questions about observers and their data, gather new information,
and try to explain events that break from an expected pattern. Here
we focus on reports of rufous hummingbirds that spend the winter in
the Midwest and Southeast, rather than in the more typical Mexican wintering
grounds.
Learning
Outcomes:
-
Observe
a hummingbird distribution map. Understand that the rufous hummingbirds
spotted this winter were north of their normal winter range.
-
Understand
that scientists ask questions about observations, climate, and other
types of data to make sense of unusual findings.
-
Pose
theories about how rufous hummingbirds might survive the winter
in the United States.
-
Discover
scientists' theories about the adaptations and other factors that
enable some rufous hummingbirds to overwinter in the United states.
