? In honor of #EarthDay, check out the very first object our Curator of Philanthropy Amanda Moniz has collected. It's a nest box for Eastern Bluebirds!
Bluebird societies date to the 1970s. A species native to North America, the Eastern Bluebird population declined drastically during the 20th century as urbanization and other developments changed the cavity-dwelling creatures' habitats. Another threat came from non-native birds, such as the European Starling and House Sparrow.

Amanda shared the story of these nest boxes on the blog. Check out the link in our profile: http://s.si.edu/bluebirds
