Suggestions for Analyzing Hummingbird Migration Data Here are some ways you can use the migration data you'll find in each report: 1. Plot today's sightings on a map of North America. We suggest using color-coded stickers, with a different color to represent each 2-week time period. 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? In what ways are they similar, and how are they different? 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 now? 6. During the 2 weeks between migration updates, 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 by our next update. Make a list of the states and provinces which you think hummingbirds will have reached by then.
