Note: These Challenge Questions coincide with the Spring 2006 Reports Challenge Question #1 From: Kristin Olson <olsonk@cedar-falls.k12.ia.us> Date: Mon Feb 13 2006 - 16:23:04 EST We think the hummingbirds need to come up north as it gets too hot and humid during the summer for them around the equator in South America.
