An important paper was just published in the prestiges, ornithological journal, Western Birds—Sexually Dimorphic Plumages Characteristic in the Northern Black Swift written by Colorado authors, Carolyn Gunn, Kevin Aagaard, Kim M. Potter, and Jason P. Beason. The paper, all of it’s science all taking place in Colorado, discusses the implication of the depth of the tail fork as an important feature in determining sexual differences.
The paper credits, in part, contributions made by the Denver Field Ornithologist, Education and Conservation Fund and the Colorado Field Ornithologist. Everyone reading this post is probably a member of one or both of these fine organizations.
