To celebrate its centennial, the Cornell Lab of Ornithology commissioned Ink Dwell to paint a 2,500 square-foot mural titled From So Simple a Beginning: Celebrating the Evolution and Diversity of Birds. The mural depicts the 375 million year evolution of birds, from the 30-foot long Yutyrannus, ancestor of the first feathered dinosaur, to the tiny marvelous spatuletail hummingbird. All 270 species represented are painted to scale.
The Wall of Birds took more than two-and-a-half years to complete, with 17 months of on-site painting. It is the only mural in the world to showcase all modern families of birds.
