![]() There are only four living species that fit into this subfamily. The long words can seem confusing, but they each have meaning and include species that are most closely related to each other. So, while the main overall family name for hummingbirds is Trochilidae, the 360 hummingbird types are split, and each one fits into one of the six subfamilies. There were seven subfamilies, but Eurotrochilus is a primitive, prehistoric variety that is long extinct, so we are only including the existing six on our list. Scientists have divided different types of hummingbirds into six subfamilies. Like all big extended families, there are smaller units within the main grouping. Attracting fruit flies is a great way to support different types of hummingbirds in an area. They hunt small insects and spiders to feed their young. This method of switching off their physiological engine for short periods is called torpor. Unlike bears that hibernate for long periods, hummingbirds may only need to slow their metabolic functions for a few hours during a cool night or if food conditions are poor.
