Puff at his birthplace at one year of age, months before dispersal
Here in San Francisco, I’ve been able to follow about a handful of youngsters after watching them grow up in their separate families, after dispersal, after finding mates and territories of their own and then raise their own litters. This is an update and a slight expansion upon what I previously wrote about the fella I call “Puff”.
When coyotes first disperse, I lose track of them — many I don’t ever see again — so you can imagine my thrill whenever I find any of them again as full grown alphas and territorial claimants in their own right.
Puff is one of those: At three years of age, he has become the new alpha male in the Presidio — across town from his birthplace — after dispersing at over a year-and-a-half of age. I don’t normally state locations, but the coyotes there have already been heavily advertised in the Presidio, which is vast in size, so I don’t feel I am compromising their situation. And it is there that Puff has now become a dad, with all the attendant responsibilities of that role, including intense patrolling, keeping outsider coyotes out, guarding against dog intrusions, and bringing in food for the youngsters! In coyote families, dads help raise the young on a par with moms. So Puff has come of age in a new territory!
About the label, “Puff”. All the coyotes I watch I label according to a characteristic which helps me identify them. I rarely share these, but here are a few more as examples: Chert is the color of the chert rock, Silver has a silver patch on his back, Squirrel sat below a tree filled with squirrels. Scout was an explorer. Puff was a puffball. When a new mate joins a coyote I’ve been watching, I pair up the name appropriately: Bonnie’s new mate became Clyde. Scout’s new mate became Scooter.
It’s my first-hand documentation work that led me to the connection between the new Presidio alpha male and the youngster I watched grow up: no one else in San Francisco is or has been doing this kind of family-life documentation work. My DNA study will confirm my observations with harder facts for the hard-core “scientists” out there.

As a youngster, Puff was a playful teaser — the prime mover and leader of his large litter of which there were four surviving siblings (several died before the end of their first year — killed by human negligent acts, including a car). Play fighting was how they passed the time: this activity, as might be expected, segued into true fighting as the males matured, and at 1.5 years of age, Puff and a brother teamed up to aggressively drive out a third brother — I was there to witness and photo-document the event.
However, I did not witness the actual trigger that drove Puff himself to disperse, if indeed there was one. I’ve watched coyotes disperse anywhere from 9 months to 2.5 years of age, where some were forced to leave by other family members (brothers, fathers, mothers) and some moved away without incident on their own timeline. Amazingly, I’ve been able to follow three of the four all four [updated] survivors in Puff’s litter to and at their new locations where they all are now parenting litters of their own which were born in April. I stay well away from den areas because this is what the coyotes would want, so I have not yet actually seen any pups this year, but I see all the moms who are obviously lactating.
Puff’s new mate is a coyote I call “Wired” (so named because of the radio-collar). The two of them took over the Presidio territory by force from the previous long-time territorial coyote residents there (as per a surveillance camera video capture at the Presidio).
Pre-Presidio, Wired had quite a story of her own: I was able to keep track of her as she roamed, looking for a place of her own. She even viciously pursued another coyote throughout the city after taking over and claiming that coyote’s territory: it turned out that this would be only a “temporary” takeover. Coyotes are well known for being opportunists, and she found something better! She ended up with Puff in the Presidio.
Puff’s birth territory has been abandoned by his parents and inherited by a sister who now is the pupping alpha female of that area. His Mom is still around but keeps a low profile. I’ve seen his Dad around, but not as the alpha male he had been. Oldsters get pushed out by younger reproducing pairs either from within or without of the family. And I’ve actually seen an older territorial pair leave a territory voluntarily, thereby ceding it to a daughter! THAT pair was seen several months later about a mile away, looking decrepit, worn-out and old. I have not seen them again and guess that their lives ended. Might they have known this was coming?
Immediately below is a recent photo of Puff and one of his new mate, “Wired”, and below these, several of the many photos I took of Puff and his siblings months before their dispersals.
