A male Standardwing spreads its wings, raises its long shoulder plumes, and opens the ornamental shields on its chest. This account is limited to Alfred Russel Wallace's historical observations recorded in 1859.
Wallace wrote that males repeatedly flutter their open wings, erect their long shoulder plumes, and expand the ornamental shields on either side of the chest.
Wallace described it moving constantly among lower forest trees and flying from branch to branch. He wrote that it fed mainly on fruit and might also take insects.
