Why do some hummingbirds sit and some hover?
Hummingbirds are extremely smart and have a terrific memory. A hummingbird's brain is very large in comparison to their body size. They know every flower in their territory and how long it will take each flower to refill.
Hummingbirds remember year to year, where each and every hummingbird feeder is, both at home and along a migration path. Female hummingbirds have been observed watching older female hummingbirds building a nest to learn some tricks and tips (and possibly steal some material). They also learn which people are the ones responsible for filling hummingbird feeders, and which ones don't. They are just bright little birds!
