Examining the Hummingbird

When Nancy takes the hummingbird out of the bag, she looks at it carefully to figure out what species it is, whether it is a male or female, and how old it is. She has banded thousands of hummingbirds, so she can do this much more quickly, easily and accurately than someone without her experience.
