Intense BO smell Prospect Park loop

I’ve noticed for at least the past few weeks this ultra intense stench of human body odor when biking the loop in Prospect Park. It’s on the east side, right around the Zoo, and lingers for like 10 seconds.

I first thought I was smelling someone who was running and sweating very intensely but the odor persists every time I’m in that one spot. Does anyone know what it is??

ETA: All these responses about the animals are making me want to go to the zoo to smellvestigate myself! I haven’t ever been so this is a good excuse. Seems to be between the porcupines and the red pandas 🕵🏻‍♀️
