A pugnacious species known for its copper penny coloring, the Rufous Hummingbird is at a crisis tipping point. If climate change continues unchecked, 71% of their current breeding range—and over 50% of their winter range—could be lost. With 3 billion birds lost since 1970 and one-third of U.S. birds in need of conservation action, we must work harder than ever to protect those that remain.

Their future, and the future of many species in a similar situation, depends on what we do next. Will you do your best for birds in this time of crisis?
