Whatever Happened to the Marsh Hawk and Sparrow Hawk?

A look at how birds' names change over time.

This story comes to you through a partnership between Audubon and BirdNote, a show that airs daily on public radio stations nationwide.

A listener recently wrote us: "Years ago, some of the birds at my feeder were the rufous-sided towhee, Oregon junco, and ted-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.

The red-shafted flicker, on the other hand, was lumped with the yellow-shafted flicker, because so many hybrids were found. Now, they all fly from tree to tree as the northern flicker.

But where have the "marsh hawk" and "sparrow hawk" gone? Check your field guide for the northern harrier and the American kestrel.

Harris Hawks and Kestrels

If your urning to see Harris Hawks and Kestrels, plan to visit the Pocosin Lakes NWR, in eastern NC, were in the winter months, you can see all you want, but hurry, a major wind developer is trying to get a large wind turbine array in the area (which is a poor to marginal wind energy potential.

Sparrow Hawks/American Kestrels

My little nephew was just telling me all about the American Kestrel yesterday. The local Raptor Center brought one to his school last week and he was enthralled. I haven't seen one in the wild since the local farmer sold his land to a housing development. Sad, really.

Also the Lousiana heron is

Also the Lousiana heron is now the tricolored heron. And the solitary vireo is now the blue-headed vireo. Found that in a field guide I had in college
