The other morning, Bonnie was playing with her buddies in the sandy area of Jack Darling Park, when we heard some constant fairly high-pitched barking and yipping. There were two coyotes out beside the tennis court, just outside of the dog park, looking at the dogs and the people in the sand pit, and making quite a racket. It seemed as if they were calling for a third coyote who was in the dog park, though we didn’t see any others.
The dogs playing in the park ignored the coyotes completely, and just carried on running and chasing and wrestling, as if there was nothing different about this particular morning.

The prevalence of urban coyotes astonishes me. I was parked on a retaining wall outside someone’s fenced yard halfway through a walk last year, and suddenly a juvenile coyote burst out from under the fence, shot past me and disappeared into a wooded space on the other side of the road, visible just long enough to be identified. Yike.
We’ve seen them on local streets many times over the years, as well as down the street in Sam Smith Park. I think the coyotes are around us more than we realize.
