From Bob and Bruce:

Overnight, about 3:45 a.m., coyotes were heard yipping and yodeling in the Eddy St. ravine JUST west of California Ave. (Basically behind the soon to be Morgan Junction Park. Owners of outdoor pets need to be aware that this is still a “shared environment” and quite near Lincoln Park’s wild spaces.

That would likely be not far from where this coyote photo/video report originated.
