some ways you can use the migration data you'll find each week:
today's sightings on your own map of North America. We suggest using
color-coded stickers, with a different color to represent each 2-week
2. Record the dates hummingbirds have been reported at each location. What patterns do you see? Based on these sightings, can you identify waves
of migrants moving in certain directions?
3. Discuss or journal: How do the migrations of the 2
hummingbird species compare? Use printable handout for your data analysis.
4. Discuss or journal: Which ruby-throated hummingbirds
do you think might have CROSSED the Gulf of Mexico? Which do you think
might have flown AROUND the Gulf of Mexico? Where do you suspect hummers
may have over-wintered this year?
5. Discuss or journal: What can you say about the temperatures
in those states where hummers were spotted in late February? In March?
What are the daily high, low and average temperatures in these states
6. During the migration collect daily
weather maps from your newspaper (or download weather maps from
the WWW). Pay careful attention to temperatures and weather conditions
in those regions where hummers have already appeared.
7. Predict how far north each species of hummingbird will have
traveled each week. Make a list of the states and provinces
which you think hummingbirds will have reached by then.
