Hummingbirds are small, migratory birds that are found in many parts of the world. In Colorado, hummingbirds typically arrive in the spring and summer months to breed and raise their young. They then migrate south for the winter, when food is scarce. The timing of their migration can vary depending on the weather and food availability, but they typically leave Colorado in September or October.
Hummingbirds are an important part of the Colorado ecosystem. They pollinate flowers and help to control insect populations. Their presence is also a sign that spring and summer are on their way.
