A pugnacious species known for its copper penny coloring, the tiny Rufous Hummingbird is facing a big problem: If climate change continues unchecked, 71% of their current breeding range could be lost. This beloved species is also already at its tipping point, having lost 50% or more of their populations in the past 50 years and are on track to lose another half or more in the coming decades.

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