The Memorable Gray Fox Blackie
Reaching back in time, there were a handful of gray foxes that stood out and each has made an indelible mark on my memory. One such gray fox I called Blackie. From the very first time that I saw him, he did not act like most of the other foxes that I’d met for the first time. Instead of being skittish, then gradually accepting my presence, he immediately approached.
We had cameras on Harbor Hill, and one morning at about 7:30 I walked along the backside of one of the water treatment plant’s buildings. I came around a corner. Ahead the ground rose and there were two large eucalyptus trees topping that small rise. From between those two trees, a gray fox emerged. I stopped, slowly lifted my camera, and took several photographs of him. He stood there for maybe 30 seconds or so before he came trotting up to where I stood. I was astounded. I had never known a fox that was so forth coming. He just looked up at me. I assessed him, wondering what might have made him so comfortable around me. I also noticed that he was slender yet muscular. He lacked much of the reddish and white coloration on his chest. He looked dark. Right then and there I decided to call him Blackie.
For the next month, he popped up here and there along the trails as I swapped out SD cards from the cameras. In that process, he shifted his territory from Harbor Hill over to Fox Hollow where Mama Bold and Gray had their natal den. Their daughter, Pale, with just the opposite coloration from Blackie, had tried to disperse, but failed and she had come back into her parent’s home range.
For a while that was okay with Mama Bold and Gray, but as it turned out, Pale took a liking to this little tough, gray fox Blackie. They began hanging out with one another; obviously pairing up. I noticed that as this relationship developed that Gray was becoming a bit concerned about what was happening: His daughter was supposed to have dispersed, but she hadn’t and now she had paired up with Blackie. They would be a strain on resources if they remained in Bold and Gray’s home range.
One morning I walked through Fox Hollow on my way to my car. Gray lay off under the edge of the brushline near the steel gate. He didn’t move. On up the road near the truck washing pad, Blackie came trotting toward me. I chattered at him, and instead of he just continuing down the dirt road, he followed me. Several times I tried to shoo him off, but that did no good. At the car I again tried to get him to go back down the road. He just sat near the gate about 10 feet away. I climbed into the driver’s seat and the next instant Blackie was on the hood of my car peering in at me. He cocked his head left, then right a couple of times. I got out of the car. Blackie jumped to the ground. I shouted and ran at him. He ran back down the dirt road. I drove away.
Several days later, again in the early morning, I sensed that something was wrong in fox land, but I couldn’t put my finger on just what it was. As I walked through Fox Hollow, ahead near the truck washing pad, sat Blackie. Between he and I, Gray stood on the dirt road staring at Blackie. I stopped, took a couple photos, and waited. Blackie trotted over and into the coyote bush thicket across from the truck washing pad. Gray moved to the road’s edge and I walked past him, heading for my car that was parked in the high-tech complex. There at my car, I had the trunk lid open and I was putting away my camera and a few other items, when suddenly, Gray quick-trotted past me and continued on down the sidewalk toward the coyote bush thicket. I watched and waited. Suddenly, from off in the brush, there came the screams and “shouts” of two gray foxes fighting; obviously Gray and Blackie.
From that morning on, Blackie and Pale moved their home range over onto Harbor Hill. Gray never to my knowledge ever went over there to visit, but Mama Bold made it a regular place to go and check in with her daughter. The two of them had a strong mother-daughter relationship.
Early one morning, shortly before sunrise, I drove along Embarcadero Road, heading for the trail cameras on Harbor Hill. As I made that sweeping right turn on Embarcadero Road, headed out toward Byxbee Park, flying directly toward me at windshield level came a Canada Goose. I slowed and wondered whether that bird would hit my windshield. At the last moment it gained enough altitude to barely clear my car. Its tail feathers looked ragged and some wing feathers had been dislodged. It landed about 20 feet behind me out in the middle of the road. I stopped.
It was only then that I saw Blackie in a fast-trot rushing toward me in the middle of the road. He had but one thing in mind: Catch that goose and have it for dinner. The distraught, honking goose floundered over onto the oncoming lane of traffic. Blackie trotted toward the goose. I shouted at him. Out of mindless fear, that goose ran, flapping its wings with all of its might, and somehow it lifted off, sailed between two large trees along the road and landed in the airport. Blackie just stood there and watched it go.
Until next month, enjoy the wildlife living in your backyard, and keep them safe.

Read the latest about Bill in this new article posted on Palo Alto Online: Experts push for creek naturalization after rare beaver died in Palo Alto
Bill was interviewed for an article in the San Jose Mercury News about the effects of noise pollution upon wildlife. The article is yet to be published.
If you or your organization would like to have Bill aka the Fox Guy present one of his four PowerPoint presentations:
1. A Year with the Urban Gray Fox – MOST POPULAR
2. Human Development, Sixth Mass Extinction & Gray Foxes – An historical look at how we got to our present place in history.
3. Gray Fox Cognition – What & How Gray Foxes Perceive – This is a speculative attempt to get inside the mind of a gray fox
4. Corridors & Connections – Sustaining the Health of Our Wildlife – The title says it all
Contact us here https://urbanwildliferesearchproject.org/contact/ and let us know that you would like to have the Fox Guy give a presentation to your organization, corporation, or a home visit.
On June 14, Bill gave a short presentation in the Elephant Room at Safari West, at 8:00 PM. We had a full house and, in the Q, & A segment several interesting questions were asked including, “In the community of gray foxes, do you think there are any LGBTQ foxes?” I replied, “Yes. Science has shown that there are such individuals in many mammal communities. In the fox community, there are some that never pair up with a mate of the opposite sex.”

Grey Fox General Health
NEWS FLASH — There are a pair of gray foxes in the Palo Alto Baylands Nature Preserve. They have denned up on the north side of Matadero Creek. The family of red foxes along with a coyote pack of five – four youngsters and an adult — have moved into the territory. Presently, we are monitoring them.
Gray Fox, Baylands Goals
Within the permit that allows the Urban Wildlife Research Project to conduct its study of the behavior of the gray fox at the Palo Alto Baylands Nature Preserve, the objectives covered are:
- Monitoring of urban gray fox Denning sites in Palo Alto Baylands.
This is being accomplished during the period when the gray foxes use a den site. It is one of the prime locations for gathering most of the behavioral data of the litter and for adults alike.
- Assessment of status and population trends of Baylands urban gray foxes.
Since January 2019 a pair of resident gray foxes have claimed territory at the Palo Alto Baylands Nature Preserve.
- Identification of habitat features that promote the presence of urban gray foxes.
The Urban Wildlife Research Project is working on a project to remove the concrete from Matadero Creek that will create linkages and corridors between the Santa Cruz Mountain Range and the Palo Alto baylands..
- Assessment of reproductive success and identification of factors that promote successful reproduction.
Open the pinch-point along Matadero Creek by developing thickets that link one area to another, instead of the present island-like habitat.
- Identification and assessment of possible dispersal travel routes.
Dispersal routes move between the Palo Alto Baylands Nature Preserve and the Shoreline region over in Mountain View. In a north-westerly direction the dispersal corridors run just behind the homes bordering the marshlands in East Palo Alto.
