Male and Female hummings birds have different characteristics. A male has a a darker set of feathers. A female has light feathers. Some humming birds have a ruby-throated meaning they have metallic green backs and appear brighter.
Hummingbirds are fast and can escape from predators quickly if they find shelter but some don't make it. Predators to the hummingbirds are family of cats and hawks. This makes the hummingbird easy to catch cause of the cats that can climb the trees and branches.
Hummingbirds fight for war and peace when in a garden. Hummingbirds are yet so tiny but fight for dominance. They fight for mates or for food. If a hummingbird cannot fight for its mate it is considered weak. As for food there is always rivalry.
Overtime the hummingbird species may change. Whether it is the male species with its ruby throated and female with light colors. There is a 50 percent chance the offspring may be dark coming from both genes of the parents.
