Challenge Question #1:
"If different hummingbird species are so difficult for humans to tell apart, what clues do you suppose hummingbirds use to recognize one another?"
Answer: Hummingbirds use their communication skills to decipher one hummer from the other. Their body coloring may also have a lot of indications for differences. Location also has a lot to do with recognizing. You wouldn't normally see one bird that indigenous to the Southwest in the Northeast.
