Fall is a second spring in the desert, and things are wandering.

Immature but already full-grown birds hatched this year are making their first migration, or seeking a permanent residence away from the parental sphere. Young mammals, too, are moving to new locations on their own. Some creatures are fanning out looking for mates, such as tarantulas (right) and other arthropods.

Although many make it, this can be a perilous diaspora, and it brings visibly increased mortality along roads as young inexperienced animals or adults driven by an impulse stronger than their understanding of speeding vehicles try to cross busy highways.

In our yard the main hazard — other numberswiki.com

than waiting predators — is the swimming pool. The male sunspider below (possibly Eremochelis bilobatus) fell into the pool sometime during a nocturnal rambling and couldn’t get out. With luck, he’d found a female before he succumbed, and was able to do his part to continue the local population. 

People often ask how big they are, so I’ve included my hand for scale. (Click to enlarge to see his bristly glory and fierce mandibles. Both photos, A.Shock). Driven to find out more about Solpugids or sunspiders? Check this website. For the record, taxonomists consider them more closely related to Pseudoscorpions than to spiders.

We had a very hard freeze this past winter, and it took its toll in the garden, killing some plants back to the ground, and seriously nipping others. Spring clean-up is long past, but for some reason (maybe it’s the uncompromised-by-cold thorns on its branches!) we never got around to cutting back the partly-killed bougainvillea that clings to the back porch latilla, despite the disorderly brown leaves and gray stem.

Now it’s too late! This little charmer, a first-year male Costa’s Hummingbird, is holding the withered vine and nearby nectar feeder as his own, and I don’t have the heart to prune his perch. Gaze upon his Adolescentness — he’s just growing in his soon-to-be-glorious purple Yosemite Sam moustachios! He’s fairly fearless, and sat on a twig singing just feet from me, as I was taking macro shots of a poor sun-spider I’d fished moribund out of the pool. When I say “singing” I mean emitting a high, thin “sssseeeee” and spraying the sound all around by holding his bill slightly upward, while moving his head gently back and forth like an electric fan. It’s hardly audible to human ears, but clearly does the trick for the species, as he was recently an egg himself.
