The problem with identifying birds is that we often see them only for an instant, or we see birds that appear superficially similar, that have no outstanding field marks, or that are far away or poorly lit.
The solution, write Kevin Karlson and Dale Rosselet in this exciting new addition to the Peterson Field Guide series, is to stop concentrating on plumage and bare-parts details, at least for the time being, and to begin anew: that is, to start the ID process not with traditional field marks but with an assessment of size, body shape, structural features (the bill, legs, neck, wings, tail, and head), and behavior, and then, if there’s still time, to move on to feather details, general coloration, habitat use, and vocalizations.
The authors have studied not only birds, but how people learn about birds, for years. Karlson is a widely traveled tour leader, an accomplished wildlife photographer, and a coauthor, along with fellow Cape May super-birders Michael O’Brien and Richard Crossley, of the revolutionary The Shorebird Guide (Houghton Mifflin Harcourt, 2006). Rosselet is vice president for education for the New Jersey Audubon Society and an experienced environmental educator who oversees the group’s statewide education programs.
Birding by impression, they argue, will free new and casual birders from forever referring to their field guides and result in an intuitive, right-brain kind of species recognition that is “similar to knowing a friend or family member’s shape, movements, and essence at a distance without seeing any details.”
We say, Bring it on, and thank you! We published an excerpt, the chapter about sparrows, in our April 2015 issue.
