The Amazing Hummingbird
... They are the only birds that can hover - simply by moving their wings in a repeated figure 8 motion. Those that migrate over the Gulf of Mexico can do so in a 500-mile non-stop flight. They can muster flight speeds of 25-30 mph, or 60 mph when diving. 30% of their body weight consists of flight musc ...

A companion bird of a different species may help, but a true opposite sex of the same species may throw the bird into even more confusion, or they may copy each other, and you end up with two plucked birds!

Bird flight
Flight is the main mode of locomotion used by most of the world's bird species. Flight assists birds while feeding, breeding and avoiding predators.This article discusses the mechanics of bird flight, with emphasis on the varied forms of bird's wings. The specifics of hovering, take-off and landing are also examined. Additional adaptations of bird's bodies relating to their flying ability are covered. Finally, theories on the evolution of bird flight are discussed.
