These animals can provide a lot of entertainment when you observe them as I've done in both Central Park and Riverside Park over the years when I've encountered various types including Cinnamon Variant squirrels, Black squirrels and Eastern gray squirrels.
On July 8th 2020, shortly after NYC started to begin easing up on lockdown restrictions (many of which were subsequently put back in place) which had been in effect since March due to the devastating consequences of the coronavirus pandemic, I had the chance to watch squirrels from my window for they began to visit the Ailanthus Trees in my buildings courtyard and as you might surmise from the photo-ops atop this entry, their antics gave me many reaons to smile during those isolating times.
