Why Some Birds' Names Have Changed





Remember the Rufous-sided Towhee?
A listener recently wrote us: “Years ago, some of the birds at my feeder were the Rufous-sided Towhee, Oregon Junco, and Red-shafted Flicker. But I can’t find them in my current field guides. They're gone, and so are the marsh hawk and sparrow hawk.” 
Well, the listener’s right. Some of these long-familiar bird names have passed into history.

The study of birds, like any science, remains a work in progress. New findings about birds’ DNA or other attributes bring changes in classification of species, which often result in new names. Take the Rufous-sided Towhee, found across North America. Differences between its western and eastern forms – plumage, songs, genetics – brought an official split into two distinct species: the Spotted Towhee in the West, the Eastern Towhee in the East.
