Size
The size difference between broad-tailed hummingbirds and ruby-throated hummingbirds is a key distinguishing feature between the two species. Broad-tailed hummingbirds are slightly larger than ruby-throated hummingbirds, with a body length of 3.5-4 inches compared to 2.8-3.2 inches. This difference in size is most noticeable in the length of the bill, with broad-tailed hummingbirds having a longer, more decurved bill than ruby-throated hummingbirds.
The size difference between the two species is thought to be related to their respective habitats. Broad-tailed hummingbirds are found in the western United States and Canada, where they inhabit a variety of habitats, including forests, meadows, and deserts. Ruby-throated hummingbirds, on the other hand, are found in the eastern United States and Canada, where they inhabit primarily forested areas.
The larger size of broad-tailed hummingbirds may give them an advantage in foraging for food in open habitats. Their longer bills allow them to reach nectar from flowers that are located at the bottom of long, tubular flowers. Ruby-throated hummingbirds, with their shorter bills, are better adapted to foraging for food in forested areas, where they can easily reach nectar from flowers that are located at the tops of trees.
Understanding the size difference between broad-tailed hummingbirds and ruby-throated hummingbirds is important for a number of reasons. First, it helps us to identify the two species in the field. Second, it provides insights into the evolutionary history of the two species. And third, it helps us to understand the ecological relationships between the two species.
