Back Home

Desert Boy and I just returned from a lovely adventure, which will be featured in next Monday's Desert Destination. But to give you a teaser, it involved all the elements needed for a successful trip:
Getting Dirty

Playing in Water

Hiking until Utterly Exhausted

Desert Destination: A Snow Patch High in the Mountains

Every Monday we visit a desert destination.
In the heat of the summer, with the desert sun baking the valleys, it's time to take to the mountains. We went hiking with the cousins and were lucky to find this patch of snow. 
We couldn't resist playing in it...
And before long it became a contest to see who could slide the furthest. Riding double was the winner.
Too bad we couldn't bring the snow patch back down with us. At least we can look at the photos and imagine how cool snow feels, especially when you go a little too fast down that snow slope and get snow down your shirt.

Stay cool!

Desert Boy and Henry Test Their Teeth

I'm living with two boys, two baby boys, two baby boys who are teething. One is a human boy, and one is a puppy boy, but they sure have a lot in common. Every day they both are chewing on a lot of things.
Fortunately, living in a rural desert area means we can leave things scattered around the yard and they won't get stolen or rusted from rain. So they both have lots of things to chew on as they wander around. And they do.
But sometimes having inanimate objects to chew on isn't good enough. The other day Henry took a little nip at Desert Boy. This happens often, and usually Desert Boy is able to deflect him. This particular day, Desert Boy got mad, turned to Henry, and nipped him back. He just grabbed the puppy, sank his teeth in, but Henry's skin is so loose he just got a little bitsy bite. I scolded them both and then tried my best to keep from laughing out loud. It was such an unanticipated movement, but clearly Desert Boy was going to show Henry who was boss.

Celebrate Pollinator Week

Bee in tufted evening primrose (Oenothera caespitosa)

I recently learned from Bug Girl's Blog that the week of June 22-28 is Pollinator Week. Okay, so today is the last day of the week, but you weren't really planning on running out and celebrating it, were you?

Here are a few facts from www.pollinator.org that might make you decide to have a party after all. Pollinators are responsible for pollinating over 75 percent of flowering plants and 80 percent of the world's crops. They help produce $20 billion of crops each year, despite the fact that 3,000 acres of farmland are lost each day.

In honor of these awesome and often overlooked pollinators, I have some photos showing these pollinators in action. After taking a look here, go out and give the pollinators in your neighborhood a high-five. Well, you really shouldn't touch the wildlife, but give them a mental high-five. They'll appreciate it.

And for those who think that there aren't many pollinators in the desert, in our valley alone we have over 200 species of bees, 150 species of butterflies and moths, 4 species of hummingbirds, and many species of bats, small mammals, beetles, ants, and wasps.

Scatology: Who Left the Poo?

Scatology is the study of scat, otherwise known as poo, doo-doo, feces, turds, dung, excrement, and other terms that are not kosher to write on this family-friendly website. Scat is the "technical" term for what comes out after something has been eaten and digested, and it can tell you a lot. Over the years I've looked at a lot of scat. The desert is a great place to look for scat. It doesn't decompose all that fast, so there's lots of scat around, and if you're a scatologist, you're in luck.

Most of the scat I see comes in two forms, pellets or turds. The photo above shows jack rabbit scat, with rounded form and brown color. Rabbits are herbivores, so their pellets all have about the same consistency. Other pellet scat found in the area include deer, elk, and pronghorn antelope. 
This scat is obviously not a pellet and it obviously does not have uniform consistency. If you look closely (you can click on the photo to see a larger version), you can see bone fragments and matted fur. This animal is a carnivore, it eats other animals. To determine what animal left this scat, I look at the size and shape. Blunt ends are left by cats, and it's about four inches long, so it appears to be bobcat scat. 
This scat has some similar characteristics to the bobcat scat, but it seems hairier and is smaller. The animal was probably eating mice and voles. The ends are tapered, which means that it is from the dog family, which includes coyotes and foxes. Based on the size and habitat, it's probably gray fox scat.
Here's some more pellet scat. If you look carefully, you can see the pellets aren't rounded like the jackrabbit scat at the top; instead they have a pinched end. This is deer scat.

Now I want to make sure that you notice I haven't included Desert Boy in any of these photos. I do have some sense of propriety, plus I know all too well that just seeing the scat wouldn't be enough for him to learn about it. 

I've done some talks about scat for school kids, and one of my favorite ways to help them learn about different types of scat is to show them a variety in ziploc bags. Then I ask them how to tell the difference between old deer scat and new deer scat. After I hear a couple suggestions, I tell them that the best way is by taste. I secretly put a Raisinet in my fingers, pretend to open the deer scat bag and pull out a pellet, and put the Raisinet in my mouth. All the kids look aghast until one figures out what I've just done. I've always wondered if any have gone home and tried to do the same thing with their parents.
