That does seem a bit too urbanish for a coyote sighting in The People's Republic of Cambridge.
I see them and hear them howling during summer nights and after winter nor'easters up the street from my house. A lot of the people taking walks down that way run into them. I saw one eating a wild turkey (which I'm sure you've seen a lot of them everywhere) in the Blue Hills in Milton. That was pretty wild to witness. I've also seen them chase a deer out onto the ice at the Quabbin Reservoir. A pack of 6 - 8. The next day we went back out and bald eagles were finishing off the carcass.
I was chased by a male Turkey in Brookline last summer looool. It was hilarious. My buddies were laughing and this thing was quite upset at me for daring to get a bit close to one of his harem lolol. Tough guy. Same with Canada geese.
I have at least 15 rabbits in my backyard. They've been increasing in numbers for the past 10 years. They're way too cute and more enjoyable to us than a nuisance, TBH.
