Birdfeeders in Riverside Park are almost empty again. So who’s eating what?
Besides a hungry Downy woodpecker, the feeders attract mostly mourning doves and sparrows. On the ground below, scrounging whatever seeds fall, are rock doves, aka pigeons, and squirrels.
Birdseed isn’t the only thing the squirrels are munching. They’re eating acorns. Gobs of acorns.
This is the treasure the bushy-tailed guys in gray are so busy burying. They won’t remember where they hide them, but they’ll find them anyway. By smell. Scientists buried nuts squirrel-fashion in an area where squirrels had also buried nuts. Then they watched. The little guys dug up scientist-buried nuts at the same rate as nuts they had buried with their own paws. That pretty much rules out memory.
Here’s something they don’t have to dig for. Smashed pumpkin. Not sure if someone brought it to feed the animals or heaved it over the Great Wall just to watch it explode. Either way, squirrels probably enjoy a little taste. Raccoons certainly do.
Raccoons eat pretty much anything. I mean, anything. Fruit, nuts, berries, corn, crawfish, snails, frogs, small snakes, eggs, baby birds, lizards, grubs, earthworms, insects. Oh, and garbage. Yum.
Raccoons do so well in the city partly because they have no predators here, other than the occasional rogue dog. Sadly, two Central Park raccoons tested positive for rabies this week, bringing Manhattan’s 2009 rabid raccoon total to four. Since Manhattan usually has no rabies at all, this is disturbing news.
New York squirrels were also predator-free for years, but those days are gone. Red-tail hawks are back, living and breeding all over the city, including in Riverside Park, and what they really like to eat is rodents. Of which there is never a shortage in New York City. So rats and squirrels, watch your backs.
A Riverside Park Red-tail rests a minute.
No one in New York eats red-tails or any of the other big raptors at the top of their food chain. Like the peregrine falcons that thrive on formerly predator-free pigeons, or the Great Horned Owl, a rodenticide-on-wings, that showed up in Central Park in November. I recently dissected an owl pellet and found tiny mouse bones. Astonishing. More on NYC owls in a future post.

So, from squirrels to nuts, that’s what’s on the menu this week in New York City parks.
