What luck!

This morning, I found a golden egg, high up in a tree.

Nestled into the rough bark of our backyard mesquite, a magical bird had laid a golden egg.  This was excellent: what a windfall! — my fortune was secured, if only I could reach it.

But it was too far over my head, so I had to satisfy myself with longing for its golden curves through binoculars.

And guess what, it wasn’t an egg at all, but some type of -quat or other: kum-, or perhaps lo-. Yes, that was what it was: a small orange fruit, probably a loquat since a neighbor has a tree, wedged into somewhere safe by a bird, or maybe a squirrel, to be retrieved later.

Who would do such a thing, hiding a golden treasure in plain sight?  The jammer would have to have sufficient strength, beak/jaw gape, toe-grasp, cleverness and agility to handle hauling a small fruit into a tree, and stashing it on a vertical trunk.  There are several candidates, but I strongly suspect the Curve-billed thrashers, who have just fledged their ravenous brood and are working incessantly, combing every crevice in the yard to feed their greedy-gaped offspring.  These industrious foragers will eat anything, seed, suet, bug, or fruit.  And they have an eye for treasure, just as golden as loquats.

Boojum moon

“In the dark was a boojum, you see,” to paraphrase Lewis Carroll.

The javelinas, bats, and skunks get to see it like this all the time. But before last friday night, I’d never seen a boojum in the moonlight.

Turns out waxing gibbous is a good look for the strange tree.

Wild hogs in the desert…

….but not the quadrupedal kind.

One of the main attractions of following the Castle Hotsprings Road through the edge of the Buckhorn Mountains NW of Phoenix is the spring wildflower bloom. This past weekend the succulent plants predominated: Ocotillos were in full swing, and the prickly pear were starting to get the hang of it.

<< one solitary ocotillo bloom leans in close as if to check out the saguaro’s underarms. This one needs a caption, like those dweeby cactus humor books I remember from my childhood. Something like, “Stubble?, umm, I think you missed a spot.” (all photos A. Shock unless noted; click each to enlarge, it’s worth it)

This horizontal Englemann’s pear leaf sprouted buds like shrimp on a plate, instead of just around the top edge (photo E.Shock). >>

It must have been close to peak for the display of Englemann’s hedgehog cactus (Echinocereus englemannii) in explosive, glorious, hot pink bloom. The stems of these spiny succulents are only about a foot tall and their green skin is concealed by both long and short spines, so despite their numbers, the sturdy hedgehog clumps are easily overlooked for most of the year. But their pink-to-magenta flowers are up to three inches across, making flowering cactus stand out on the most brutally exposed slopes of rocky hills and arroyos. <<

They don’t need much of anything to grow or bloom — their preferred medium is stony, desiccated, mineral soil, sometimes in the scant shade of a shrub or larger cactus, sometimes not: they’re happy baking in the full Arizona summer sun, and can thrive in a crack in solid rock that even a rock wren would scorn.>>

<< One hog we found had the hugest flowers I’d ever seen: that’s E’s man-sized palm for scale, not my girly-paw.

Native solitary bees buzz in and out of the cuplike blooms, sometimes invisible except for waggling stamens deep in the throat of the flowers. Click on the photo below to see a bee-butt poking upward, right next to the apple-green pistil, which hasn’t opened fully into its star-shaped ærial panoply. You can also see the formidable armory of spines on the fleshy, water-hoarding stems. Even javelina are discouraged by them, although I’ve seen otherwise imposing boar javelinas with lips daintily reddened by the petals of the flowers of a “claret cup” hedgehog cactus. This petal-snacking would be considered hog-on-hog predation, except that neither javelina nor hedgehogs are actual pigs.

The key is the beak

A while back, I posted the latest Spot the Bird, a shot of a Mexican wetland that contained hard-to-see birds.  It was a tough one.

Here’s the key.  The hidden birds are three Black-bellied whistling ducks, visible in the sea of green only by looking carefully for their bright coral-red bills, a tag of chestnut plumage, and surprisingly, their gray cheeks which stand out more than you’d think.  Enlarge the B&W version of the photo on the left, and look for the color splashes inside the yellow oval.  Two of the ducks are together on the left, and one, the most diffucult to see, is on the far right.

Well, OK, they’re still hard to see. Here’s a color-heightened, tight close-up to help.  Disregard the bright brown clump of leaves in the middle of the field of view.

Three small pictures of four small things…

… I missed at first, when outside friday morning shooting passionflowers.

It really irked me to not have my own photo of a Gulf Fritillary to post yesterday, so once the sun was higher, I went out to fetch one, if possible (a photo, that is, not a flutterby). I ended up encountering not only the butterfly, but three other notable things. Here they are, in the order they appeared (be sure to click to enlarge, except the kestrel, which is too blurry to bother, and actually will just get smaller anyway; all photos A.Shock):

A. The Gulf Fritillary, which started it all. The insect is sort of hidden in the negative space between stems and leaves (almost a “Spot the Bird“).  This was the best photo I was able to nab — the name flitirraries would suit them even better, because they never seem to rest. They are Passiflora specialists, and are clearly thrilled that we have four vines in the yard. (Well, six vines actually — this morning I found two small seedlings, thriving about 4 feet away from where their parent plant refused to take.) >>

B. The Echinopsis in bloom (or “Easter Lily cactus”). This one is a cultivar, I don’t know which, since these shade-growing cactus have been living in this yard longer than we have. In my experience, it’s unusual to find its crepuscular flowers still open at noon. <<

C. The Fearsome Predator. >> The neighborhood male American Kestrel, about the size of a Mourning dove, checking out the Dee-licious Finch Bar (the birdfeeders) for lunch. I looked up when I heard a house sparrow give a rough alarm call; the little falcon was just 20 feet away from me, perched on a low wire with a good view of the menu. Unfortunately, I didn’t get a shot of him until he’d swooped up to the top of the corner phone pole because my trigger finger was distracted by D:

D. The Ants that were biting me painfully on the feet. Due to hastily brushing them off and sweeping them out from under my sandal straps in a undignified quick-time version of the Myrmex Dance I did not immortalize their image, although they were just doing their job, Protecting The Nest, which I’d accidentally trodden upon trying to photograph the Echinopsis. Perhaps the Gilded Flicker family who lives here (and who, I think surprisingly late, just fledged a young’un) will be making a visit to the Dee-licious Ant Bar.

Do you suppose the Ant Bar has a Formica countertop?

Bonus etymology: Formica, etc.

According to the archives of “Word of the Day”Greek murmex [is] “an ant,” which also gives us myrmecology “the study of ants” and myrmecophagous “ant-eating.” In Latin the related word for ant was “formica,” from which we have the former Word of the Day “formication,” the sensation of ants crawling under the skin. The proprietary name “Formica” applies to a plastic laminate ultimately derived from formic acid (which comes from ants), but it is also a pun—it was originally developed as an electrical insulator that could be substituted “for mica.”

For the detail-oriented, let me add that Latin formīca is the ancestor of the French and Spanish words for ant, fourmi and hormiga, respectively. The Latin and Greek words formīca and myrmex (μύρμηξ) at first glance may not seem similar to each other, but as neatly summarized by Wikipedia, both are generally accepted to be derived from the Proto-Indo-European root *morwi- along with a pile of words for ant in other languages: Latin formīca, Iranian /moirbant, Avar maoiri, Sanskrit वम्र (vamra), Greek μύρμηξ (murmēks)/μυρμήγκι (mirmigi), Old Norse maurr, Crimean Gothic miera, Armenian մրջիւն (mrǰiwn), Polish mrówka, Albanian morr, Persian /murče, Old Church Slavonic mravie, Russian муравей (muravej), Tocharian /warme, Kurdish Mérú, Breton merien.
