LIFE IN THE LOWER SUSQUEHANNA RIVER WATERSHED
A Natural History of Conewago Falls—The Waters of Three Mile Island
In addition to the Canada Geese and Snow Geese currently visiting Middle Creek Wildlife Management Area, three smaller geese of interest were seen there this afternoon.
There you have it, the three little geese—a Ross’s and two Cackling. They’re among North America’s smallest of the geese species and seldom are they seen so close together.
Our outing at Middle Creek Wildlife Management Area was today highlighted by teasing views of glistening white geese and swans—the tundra breeders that by February will create a sensation attracting thousands of birders, photographers, and other visitors to the refuge.
The Ross’s Goose (Anser rossii) is a rare but regular transient in the Lower Susquehanna River Watershed. This species nests in the arctic tundra of northernmost central Canada and winters in the valleys of California and in parts of Texas, Louisiana, and Arkansas, primarily near the northwestern rim of the Gulf of Mexico. A population also spends the colder months in western Texas, New Mexico, and an adjacent portion of north-central Mexico. The Ross’s Goose looks like a tiny version of a Snow Goose and is most often detected among flocks of these latter birds during their late winter visits to our area. Finding a single Ross’s Goose among thousands of Snow Geese can oft times be an insurmountable challenge, so it’s nice when one decides to drop by in a crowd within which it is much more discernible.
In case you were wondering—yes, despite the ice on Middle Creek’s lake, the Sandhill Cranes are still being seen in the vicinity of Willow Point.
