The most likely hummingbird population composition is a mix of different species of hummingbirds, with some species being more common than others. In general, the population composition will vary depending on the location and habitat of the hummingbirds, as well as the availability of resources such as nectar-rich flowers and suitable nesting sites. Some common species of hummingbirds found in North America include the Ruby-throated Hummingbird, Anna's Hummingbird, and the Rufous Hummingbird.
