This is Pipa. She’s 10 years old: born in March of 2016, and radio-collared and tagged that Fall before she was even a year old. She was labeled with a number: F06. She was the sixth out of seven to be trapped and shackled with a collar that year, and purple ear-tags were punched into [ ]

Sparks’ Update in June, 2026

I ve followed Sparks story since he was born in 2019 in Glen Canyon much less so recently, but here s an update nevertheless. He s seven years old now. He s thriving as the alpha male of his territory in the Presidio where he s on his fifth litter. Last year he had seven pups, only 3 seem [ ]

Guarding Their Den Site

[Reposted from my Instagram account] This video began as 15 minutes in length. By cutting and speeding, I’ve reduced it to 2:45 minutes, which I think is manageable on Instagram. The parents are mostly guarding, but Mom messages a dog at 0:50, her mate deals with a dog in some capacity at 1:12, and at [ ]

Acceptance of Restorations . . . and New Balances, and Top Dog, by Walkaboutlou

I realize my local coyote, regionally, have seemed to change greatly. I used to hear them regularly. Or see them in distance, checking the dogs out. This has mostly ceased. They are here. I see as many signs (scat, footprints) as ever. But they literally, all of them, have become ghostlike. Now, they even rarely defy [ ]

Territorial Division and Mange

I ve written several postings with information about mange. One on how the malady has just recently exploded here in San Francisco, and another on how weakened immune systems allowing the mange mite to proliferate on a coyote host have been linked to the use of rat poisons. But there are other stressors which raise cortisol [ ]

A Coyote’s Swim to Alcatraz

A Behavioral Reconstruction I almost always post my own first-hand observations of coyotes, supported by photographs. This case is different. The coyote’s crossing to Alcatraz Island on January 11th came to me second-hand. What follows is therefore a combination of documented sightings, dates, tide information, and physical geography, with behavioral interpretation drawn from research and [ ]

Slide Presentation as Pupping Season Approaches

Pupping season is approaching — It’s time for another talk!! Here’s the blip they put out: Janet Kessler, known as “The Coyote Lady”, is a self-taught naturalist who has spent nearly two decades documenting urban coyote behavior and family life in San Francisco with her camera, where she has come to know and identify most [ ]

Alcatraz Coyote Survived Its Swim and is Thriving

This Alcatraz Coyote update comes not from my own observations, but from what friends have sent me. This photo was taken by a tourist on January 24th, just about two weeks after the coyote made its swim, so he not only survived, but he is well and thriving. Rangers apparently have come across a bird [ ]

Same Species, Different Behaviors, by Walkaboutlou

Hi Janet, Hope you are wintering well. It s been a very mild winter here. Hardly any snow. We did fenceline checks and found the scraps of an older dead buck. The landowners knew of him via trail cams and sightings. He came to this property about a month ago. He had been shot on public land, escaped [ ]

Mange Epidemic in San Francisco

Someone asked me how I knew that our mange cases picked up in 2024 and spread so quickly and only recently. About half the coyote population here in San Francisco has been affected. And I m told by my rehabber contact, that it s about this same percentage in other parts of the state of California. The [ ]
