Happenings at a coyote den
In the fall of 2022 our foursome of camera trap enthusiasts set a camera at a coyote den in Sierra Valley. It wasn't an active den at the time, but setting a camera there in October gave the coyotes a few months to adjust to it. We lucked out. The local breeding pair settled into this den to give birth and raise their litter.
The camera recorded over fifteen hundred clips, and it took a couple of weeks to review them. Our YouTube video below chronicles the main happenings at the den over six months. See it HERE

We found a Wickiup!
We set trail cameras there in the fall of 2020 and 2021 and waited until the spring thaw to find out. This movie tells the story.

Rocky Flying Squirrel takes on the Acorn Pecker Gang
Many years ago the late Robert T Orr told me he had trapped flying squirrels at Sonora Pass in the Sierra Nevada. "I was trying to trap martens," he said, "but I kept getting flying squirrels. They were attracted to the meat I was using as bait." [Dr Orr was the curator of birds and mammals at the California Academy of Sciences and I was a teenager who hung around the museum.]
It is not uncommon for herbivores to deviate from their diet, especially when plant protein is low or pregnancy demands it. That's when innocent vegetarians like deer and rabbits shock us by dabbling in carnivory.
Carnivory probably also explains why Acorn Woodpeckers raise hell when adorable big-eyed Northern Flying Squirrels show up at their nest cavities. The squirrels are known to feed on eggs and nestling birds.
My goal to film acorn woodpeckers at their nest cavity was sidetracked when my trail camera recorded visiting flying squirrels. Rocky is such a photogenic charmer! I filmed "the pecker gang" for a year and a half on my neighbors' property, and eventually I recorded three hostile encounters with the inquisitive "Rocky". Such are the rewards of camera trapping! Have a look!
I am grateful to neighbors Ted and Judy -- the indulging hosts who made possible this little film and "Bruin Ate the Hornets' Nest".

Bears Just Wanna Have Fun
This short video is Part 2 of the "The Hanging Jug". When I realized that this title may disappoint YouTubers seeking a different genre of entertainment, I gave this sequel a different title.
If you haven't seen Part 1, you missed out on the different ways various species reacted to the jug, and you don't know that bears won the curiosity contest. That is why I devoted this video just to bears.

Bruin eats the Hornets' Nest
With this video, I can scratch one camera trapping project from my bucket list. Some years ago I figured out that black bears hit the hornets' nests rather hard in late summer. The few nests that I found were a little too lively for camera trapping. I owe this adventure to my neighbor Ted seems to have a knack finding tame nests. Anyway, the video tells the story, and I hope you enjoy it.
