Squirrels may be so common in today’s city parks that they threaten to make off with our junk food, but at one time the creatures were rare and exotic visitors whose delightful presence was carefully encouraged. Dan Lewis of Now I Know tells us that the ubiquitous squirrel may have been indigenous to North America, but Central Park's squirrels didn't come with the territory: The bushy-tailed natives had become all but extinct on Manhattan island by the 1850s due to rapid development. Just a year before the park’s creation, one lone squirrel, heading down a tree trunk on its way to extinction, stopped traffic as charmed New Yorkers marveled at the antics of the "unusual visitor" to the extent that they had to be dispersed by police, according to accounts by a paper of the day.
So how did they get here?
