Maggie's Farm

Once a common bird in New England and the Eastern seaboard but now gone the way of the Passenger Pigeon.

From Wiki:

Heath Hens were extremely common in their habitat during Colonial times, but being a gallinaceous bird, they were hunted by settlers extensively for food. In fact, many have speculated that the Pilgrims' first Thanksgiving dinner featured Heath Hens and not wild turkey. By the late 18th century, the heath hen had a reputation as poor man's food for being so cheap and plentiful; Thomas Winthrop related that they could be found on the Boston Common and that servants would sometimes bargain with a new employer for not being given Heath Hen for food more often than 2 or 3 days a week.
