Visitors to Cornell University's ornithology lab can use powerful spotting scopes, like the one shown here in 2006, to observe the activity of Canada geese and mallard ducks in a pond adjacent to the visitor center. The research facility is located in Ithaca, in the Finger Lakes region of west-central New York.
