Year of the Snake - No. 19 Diamondback Rattlesnake

On my second visit, I found this Diamondback Rattlesnake coiled and basking in the sun.
I could still see the bulge from his cottontail dinner.
At the end of May, my dad came across this Diamondback one evening while walking down the wash. (The rest of us were in Flagstaff.)  The snake was stretched out across the wash. It had just struck a cottontail rabbit, which was lying motionless.

Crotalus atrox disappears under a rock.
Back home a couple days later, I decided to take a walk, break in my new camera and try to find that snake. I went to the place my dad said the snake was. I found him coiled up under an overhanging rock. I visited him a few times over the next couple days until he moved on.


The Diamondbacks I have found do not seem as tied to a location as the Arizona Black rattlesnakes. I can usually go back and see them two or three times, but they eventually move on.

Year of the Snake - No. 11,12,13,14,15, 16, 17, 18 Arizona Black Rattlesnakes

Crotalus cerberus (yes, like the three-headed dog of Greek mythology)
Over three weekends (Memorial Day, June 1, & June 22), we spotted eight Arizona Black Rattlesnakes near Flagstaff. We had returned to a place we found last year. These are interesting snakes because they are very attached to a certain location or even rock. They will come back to the same spot year after year. 

What's also interesting is that their color changes from day to night sometimes. Individual snakes can have very different personalities. One snake would sit for hours with me watching. Another time I was walking down a creek bed and one buzzed before I got within 10 feet. 

During the hottest part of the day, the snakes hide in cracks between rocks to stay cool.

A pregnant female keeps her body temperature warm by basking on the rocks.

This male snake rattled when I was 6 feet away and hadn't seen him yet. He was coiled up under some grass. I only saw the tip of his rattle and thought he might be a juvenile. But when I pushed the grass aside with my snake hook, I found he was an almost 3-foot long adult male (large for this species).  He didn't stop rattling and struck at me twice in the 10 minutes I was photographing him. By the way, I was well out of strike range. I think it was a bluff strike.

Lizards of Note: Spiny Lizard, Fence Lizard, and Whiptail.

Sceloporus magister  shows how he got his name.
I caught this Desert Spiny Lizard trapped in a large round pipe sticking out of the ground near a cattle water tank. The pipe has a lid on it, which can trap lizards and is why I check it every time I am in the area.

These are common lizards here. Sometimes their heads are red and the males can have very blue throats. We found one recently that had a throat and stomach almost entirely blue.

A few weeks after I found a baby Spiny in an metal trash can outside our house.

Sceloporus tristichus

I found this Plateau Fence Lizard under some bricks near our house. These are very common around here and I see them almost daily on the trees. They are closely related to the Spiny Lizard, but much smaller. They both have spiny scales.

Fence lizards of various species are found as far east as Tennessee.










Aspidoscelis uniparens






This lizard was first spotted in mom's bedroom. We spied it a couple different places after that and finally caught it in our dining room. This is a Desert Grassland Whiptail. They are very common here. But this is the first I have caught because they are so fast.

These are an interesting lizard because they have one gender -- female. (Note the Latin name uniparens.) They fertilize their own eggs and all are clones of the mother.

Year of the Snake - No. 10 Western Patch-nosed Snake

Salvadora hexalepis 
I found this guy on the road on my way home from hiking. I had to hand carry this snake home because I already had a Spiny Lizard in my bag. (See next post.) I think he bit me 10 times during that walk.

We kept him for a week and then released him near our house.

These snakes have a patch on their nose for digging up the dirt to get at reptile eggs, which are part of their diet.

Year of the Snake - No. 9 California Kingsnake

Lampropeltis getula looks very nice against our 1950s carpet.
He has been released back to the wild.
I found this Kingsnake on May 23. It was in a place on the other side of the creek that we call the "Frog Ponds." He was about 3 feet long, not the longest I have found but very heavy.
His scales had quite a lot of damage, so he has probably been through a lot. I think he was hunting when I found him. He was moving along, putting his head in and out of holes.
