Busy busy busy!! And we just can't avoid that wind. Guess that's life.
I've been seeing the baby Costa's hummingbirds and they are very entertaining. One (some?) of them sits on the hummer feeder attached to the edge of the kitchen window sill and stares at me (washing dishes) for several minutes at a time. Intense staring. For a hummer to stand still for 30 seconds is rare. Several minutes is unusual - this tells me it must be one of the babies of this year, and its learning its environment. I do believe that this hummer is one of the babies. Its difficult to see in the photo, but it *is* smaller than the other Costa's adults. Its also a little duller and fuzzier.
We've also seen some Anna's hummers, which are unusual here (they occur more towards the coast) they usually leave by the heat of the summer. I like them because their gorgets are red.
The desert iguanas are starting to emerge... which means the heat of the summer is arriving!
I also wanted to share this photo. It is looking south, across the Antelope Valley, to the California Poppy Preserve. See that orange?? Those are the California poppies!! We're so close, and yet so far... At least I can share several other poppies that I've seen this spring. To the right is the small-flowered poppy (Eschscholzia minutiflora). The flower is much much smaller (desert stuff is like that...).
And this is a prickly poppy (Argemone munita), which also occurs in the desert, but this one likes washes. You can see a rodent hole behind this poppy. Probably a desert kangaroo rat, one of the cutest rodents, ever! I've never seen one, only their huge burrow holes (I have seen the more-common Merriam's kangaroo rat (Dipodomys merriami), which even live in our yard). The desert k-rats must be big, because the holes are about 4 inches across. Kangaroo rats are not rats. In fact, they have cute tufted tails. They have large legs and hop around like kangaroos. Very cute.

Spring Critters in the Desert
We're supposed to be outdoors, working today... but there's a front coming through, and the winds are up. Not only that, but the project/area that we're in is associated with windmill farms (read: that place will be even windier than anywhere else). Now, since we're supposed to be experienced field workers, we've learned a thing or two about working in the wind => it sucks (and the hubby often ends up with a sinus infection). If we have to work with others and can't change the schedule, we're now experienced enough to dress for the weather. Here we are last year, when we were working in the same area, just a different project. A friend took the photo and called it "Desert Bandits" because everyone thought we were so silly to wear those face coverings... well, by the end of a month of working in the wind, a couple folks sheepishly whispered that they wished they had those face coverings!!
For this day, we were just scheduled to work with ourselves, so we opted out of the outdoors for the day. I consider it operating costs. You see, the desert, esp the Mojave is known for its wind. We're on the cusp between the California coast and the Great Basin inland. The temperature difference between these regions creates a huge pressure differential which, in turn, creates some pretty big winds. Hence the wind farms. Its a fact of the region, and if you're going to live amongst it, you learn not to deny its reality and its power (hence the wind farms!).
Today I'll share with you a couple fun critters that we found nearly a month ago. The high levels of rain that some regions of the desert recieved were great for much of the wildlife and plants. We've been experiencing chronic shortages of rainfall, and its creating stress on everything. Usually when we think of desert reptiles, we think of hard-scaled creatures like the desert tortoise and lizards. But, when conditions aren't as difficult - at night - there are other reptiles that make their appearances - such as this fellow, the western banded gecko (Coleonyx variegatus). Yes! A gecko in the desert! On the ground behind our friend you can see a shiny metal object. That's the discarded muffler which the gecko was found underneath (actually, it has a nice, humid burrow under the muffler, which provides its delicate skin even greater moisture in the harsh desert habitat). My coworker found the gecko. Personnally, I didn't expect anything. We were on the edges of a desert town and this was one of the offroad dumping spots where people love to discard old car parts, sofa's, etc. I was just annoyed. My coworker kept working - and found life! See, the desert isn't all that deserted.
Here's a "Where's Waldo" exercise for you. Look into this photo. Do you see anything other than rocks? Look into the center. See the round "rock"? That's a baby tortoise!! Talk about good camo! This leads me to another discussion. My brother was just visiting a couple months ago and asked me, "Why does every single road have fences alongside it?"... Yup. Its a myth of the West that there are wide open places. I mean, there are, but you first have to get through that barbed wire fence to get at it. Why is this?? Well... first off, consider that its private land and the person is trying to exclude others from getting on there - either to dump garbage, hunt on it, mine it, drive an off-road-vehicle (ORV), or graze their livestock.
Otherwise, a heck of a lot of land out here is public land - U.S. Bureau of Land Management land (yours and mine, but leased out for "Multiple Use"). Its those multiple uses that require the fencing. Don't forget that a mere 50+ years ago, everything was heavily grazed for livestock (cattle and sheep). Those animals aren't like our impression of horses - grazing on grass. They also subsist on eating shrubs... and in the west, they have to, because that's what they're grazed on. Recent laws put into effect by Pres. Bill Clinton right before he left office addressed the issue of grazing on public lands in the southwest, decreasing the number of livestock that can be grazed per acre on BLM land. Still, however, the land is grazed. You might not ever see a live animal out there, but believe me, the land is being grazed. They now just usually ship the sheep herds from location to location throughout the deserts. And if the sheep aren't there - wild horses and burros still are. I seldom see them, just their tracks.
In addition, we've still got major amounts of ORV riders, and the numbers increase daily. These folks are usually supposed to stay on trails and generally are not supposed to cross highways... but nothing is perfect. I know the fences are also supposed to restrict ORV's from crossing the road just anywhere. I'm sure its also road safety, so yahoo's don't run off the highway to do donuts out in some playa by the side of the road either.
But, most importantly (to me), a new trend for these fences is to keep desert tortoises from wandering onto the highways. I mean, a tortoise looks like a tank, but put that little fellow next to even a Geo Metro, and, well, there's no contest. The one time a Geo is a big car!! As a mitigation measure on many highway and utility corridor projects, the company is also now required to install tortoise-fences on these road-side barbed wire fences. A tortoise fence is just an 18-inch tall length of hardware cloth that is attached to the fencing and slightly buried (no tunneling beneath!). Tortoises are notorious wanderers and have often been observed near roads (in addition, road surface run-off generates larger plants just alongside roads, which is called an "attractive nuisance" that entices tortoises to be near roadsides). It is suspected that these fences are saving the lives of hundreds of these critically endangered species. Little "Waldo" shown above was found just a mere 1/4 mile from Interstate-15, a 6-lane highway that I have NEVER seen empty. Although Waldo is most-likely too young to wander, here is Waldo's buddy, Wally... found nearby and just 1/2 mile from I-15. There is no doubt in my mind that Wally's life is much much safer thanks to the efforts of people to have these fences installed and maintained.

Costa's Hummingbird Chicks
Welcome to our hummingbird world! We currently have 4 hummer feeders in our yard, and are looking to put in 2 more. We have also planted a lot of hummingbird-friendly vegetation (remeber my YouTube video, Costa's hummingbird on penstomens?) - more on that in the future... In the past couple years, the hummer population in the yard has exploded! We generally have Costa's hummingbirds (Calypte costae), but occassionally we've seen/heard a black-chinned hummer (Archilochus alexandri), although they usually occur farther east. Everywhere you step in the yard, you either hear hummingbirds, or you get "buzzed" by one as it whips past your ear. They're great fun to watch, and I'll write more about them in the future...
But this spring has had a great suprise: one of the hummers built her nest in clear view of our kitchen window!! She built the next in a mesquite tree, which doesn't leaf-out until late spring, so we had a clear view the entire time to observed the developement of the nest... and then the babies.
We first observed the female busy making her nest. She would even fly around the house and pick off cobwebs to use for her nest. Eventually, this is what we saw: two little beaks poking out of the edge of the nest.

While in house, I saw a couple great "family moments" that I took a photo of. The pictures were heavily zoomed, then cropped, so they aren't the greatest quality.

Springtime Wildflowers
I'm baaack! After a long pause, I'm ready for posting again! This time I'm going to try to write less, and post more often. We'll see how that goes...
The desert and parts of SoCal have been great this spring! There were patchy rainstorms, and flowers are depending upon that. The eastern Mojave Desert got some great fall monsoonal rains and good cold winter rains. Here are some shots near Baker, CA. For those of you not in the know... the verticle line in middle of the second photo - that's the Baker thermometer, the largest thermometer in the world! Oh yeah.
This is a spot north of Barstow, CA. They got rain in some of the higher elevations. This may not look very floriforous, but its very impressive in-person.
Isn't this one great?!? This is near the windmill pass east of Los Angeles. Plants that live in drier regions develope spiney hairs to protect themselves from herbivores. This gives them a nice "soft light" when back-lit from the sun. This spot is pretty amazing... I was going to post photos of it last year as an example of one of the ugliest places I've ever worked... then we returned this year... and the high rainfall in the LA region germinated all the flowers! Well... okay, I think you just have to see this! Here's a photo from last September:
