This is the second year my cameras have caught a bobcat family in this drainage. Last year there were also three kittens. The male operates from one eye, as his left eye appears damaged. He’s the one who took down a deer fawn last year in front of the camera.

A mountain lion rests at a desert oasis
This mountain lion has been caught on my cameras on and off for nearly a year. The drainage she frequents also supports javelina and white-tailed deer, primary food sources for mountain lions in this region. When I was going to check the cameras, I came across the carcass of a deer fawn that was partially eaten and cached. I suspect that the mountain lion had very recently killed and eaten part of the fawn and was relaxing by the waterhole with a full belly.
Little Bear cools off
It’s been a pretty dry monsoon season so far here in the Sonoran Desert. The main waterholes used by local wildlife in my area are drying up due to sparse rains. The low water level at what we’ve been calling Little Bear Pool didn’t stop this black bear from taking a soak to cool down. Thankfully, more rain is forecasted for this week.
Last night’s backyard Wildlife
It was a busy time in the backyard last night. A bobcat, coyote, and raccoon came through as well as smaller critters including a packrat, cottontail, and the screech owl fledglings. All four screech owlets appear in the last clip of this video. It’s good to see they are doing well in life after the nestbox.
Owlet nestbox action
There are a few interesting things going on in this video: gular fluttering, nictitating membranes, and head bobbing. Owls and other birds use gular fluttering to stay cool when the temps are high. Owls nictitating membranes (essentially a second eyelid) help protect their eyes when attacking prey. Lastly, head bobbing (motion parallax) helps owls triangulate their sight on a given subject since their eyes are fixed in their skull and cannot move on their own.
Puma Concolor
Mountain lion, cougar, or puma, this big cat is pretty stunning in her physique and lifestyle. All muscle and articulate movement when moving through her environment searching for prey and water. This particular cat showed that she also has habits of sorts, like us, in that she pretty much mirrored her visit to the waterhole two days apart. One visit during the day, and one during the night.
A Sonoran Desert Mountain Lion
When the temperatures start to rise as summer comes to the Sonoran Desert, any water source becomes a critical lifeline for all the desert critters. Birds, reptiles, insects, and mammals large and small regularly visit these waterholes. In this case, over the course of a month, a mountain lion stopped by only once on her rounds through her territory. The water at this spot has since dried up, so hopefully there are more water sources to be found deeper in the canyon.
A thirsty mountain lion
As the days get hotter and water sources begin to dry up a small pool of water can attract big wildlife. In this case a magnificent mountain lion stopped by for a long drink.
Nesting screech owls
This is year seven for the screech owls to use the backyard nestbox. They successfully fledged offspring the previous 6 years. Typical clutches started with three to four eggs with all nestlings fledging and hanging around the yard for a month or so, while learning the ropes from their parents before dispersing. Last year there were five eggs, but only one survived to fledge (I suspect secondary poisoning from rodenticide). In this video the male brings his mate a gecko snack while she incubates her eggs.
Four mountain lions
One of my cameras was lucky enough to capture a mountain lion family at a desert waterhole. The “kittens” are close to leaving mom and venturing off by themselves.
