USFWS
We have a huge number of tiny hummingbirds to report this week. Since our May 1st update, 137 hummers have been sighted. We hope you enjoy mapping their travels! Once again, we thank Lanny Chambers for providing many of today's sightings. We also thank you for watching for hummingbirds, and reporting the FIRST one you see this spring.

- In how many states and provinces have they been sighted in total?
- Have the ruby-throats now been sighted throughout their entire breeding range?
- If not, how much further north do you expect them to go?
- To which of the following biomes do you think these hummers will migrate? Why?

- As recommended in each migration update, continue to count the number of hummingbirds reported in each 2-week interval. When do you think the greatest movements occurred? Can you find weather or temperature patterns that might have affected the hummer's migration? If so, when did these occur?
