Purple in the herbs

Our vegetable garden, like most vegetable gardens, requires continual effort.  For the majority of these domesticated types of plants, the desert is not a “shove it in the ground and it will grow” environment. Rabbits and diggy-beaked birds are constantly helping themselves, peak summer heat (now thankfully past) and dryness make frequent watering necessary.  So, we pick our battles: tomatoes, no; herbs and chiles, yes.

There are also typical ironies of gardening.  Plants that we cannot get to grow in spots we intend for them will flourish as volunteers in the most unlikely and sometimes inconvenient places.

The passionflower, Passiflora foetida, is an example.  It will not grow on the fence we’d like it to hide; we’ve tried twice, it’s succumbed three times — once, after a miraculous Lazarus act accomplished by profligate watering, all the re-grown leaves were denuded by Gulf Fritillary caterpillars, which in the plant’s precarious resurgence, finished it off for good.  (However, this fall our garden is full of gorgeous orange butterflies).  Passionflower will grow untended — unwatered, even — between cracks in the pool deck, and, of course, in the vegetable garden, using the withered and sulky tomatoes as a support.  Currently three volunteer passionflower vines (spawned from the beleaguered “lazarus” individual’s seeds) are boisterously and inconveniently twining through our herb garden.  We let them; they seem so happy. Above is a photo of one blooming at dawn this morning, growing through another one of our garden success stories, the Mexican oregano, with its less extravagant clusters of tiny white flowers.

Whether we get produce to the table or not, the garden is great habitat — young lizards abound, and this morning there was a spiffy male Costa’s hummer gnatting over the oregano, his moustaches way purpler than the lavender Passionflower he hovered over.  Periodically he would rest, perching on a wire tomato cage, and sing his thin little wispy song, barely noticeable unless you know to listen for it.  It’s their time of year: they seem to be the most numerous hummers in the yard, zipping around from perch to perch, chasing each other, “singing” and establishing their territories.  News to interlopers: our garden, rich with suitable perches, flowers and tiny winged insects, is already claimed up.

The Week in Review: the last monsoon event?

Earlier in the week we had a storm — technically outside the officially designated monsoon season — and it was a colorful one.  Our microcosm of Phoenix received about a half inch of technicolor rain in a very short time, without the wind and hail that the same towering clouds dropped on neighbors less than three miles to the east.  The storm brought amazing sunset skies, migrants, optimistic amphibians, and flowers to our yard.  (All photos E.Shock.)

Shortly after these clouds moved over the metro area, the dark skies split, pumping rain and lightning into the creosote-scented night air.

The next morning, we found an excellent red dragonfly drying its wings on barbed wire, “our” spadefoot wound up in the pool again along with the rest of the storm debris, awaiting rescue, and the Herrerrae barrel cactus’s crown of fragrant yellow and red blooms were saturated with color.  The architecturally precise buds tautly await their turn in the vortex of the flower crown — the easier-going little lemony pine-apples slouching around the edge are last year’s fruits, waiting to split open and disgorge their seeds, or be plucked and carried off by an herbivore, and left elsewhere to start a new barrel.

With luck, cactus and wildflower seeds all over the desert will be soaking up the fall moisture, preparing themselves for next spring’s blooming.

And it goes on…

It always makes me happy to see infant animals in the yard; it means the world is rolling along, as it should, species replenishing themselves and the natural systems functioning. This is why people love seeing babies — it gives the same satisfaction: that the world is carrying on as usual, despite everything, and because of everything. I feel it when seeing tiny cottontails hidden out in the open in their form, hatchling praying mantids swarming out of their bread-loaf egg-case, nest-cached hummingbirds waiting for mother to dispense nectar-and-gnat soup, even young raccoons trundling behind their mother, wreaking havoc in the yard, and young serpents making their way on the soil, searching for prey something the girth of a pencil can handle.

In the warm desert, a lot of this new life begins in fall, our functional second spring: ahead is the cool weather with its longer nights for foraging, the scorching hot temperatures are behind us. Monsoon is winding down too, a time when the intermittent deluges of late summer storms kick-start the food web after the stingy, dry weeks of early summer. This moisture encourages hatching and births, vegetation sprouts everywhere, and arthropod and rodent pray abounds, generously giving hungry young animals a solid start.

Yesterday, it was young lizards: the herb and vegetable garden we planted this year with its slightly raised-bed construction, bounded by hollow cinder blocks and stocked with minute invertebrate-rich compost, has proven to be a successful nursery for both Tiger whiptails and Ornate tree lizards. While watering, I watched three young tree lizards simultaneously hunting ants and other tiny prey: they would dash forward, whip out their tongue, swallow, and then slowly, sinuously wave their tails back in forth in an undulating movement — a slow-motion lash — that just looked like someone rubbing their hands in self-satisfaction. Each lizlet was only 2 inches long. A young whiptail, larger by species, but still young — its long tail was still faintly electric blue — was also puttering around in the vicinity, taking advantage of my shadow to hang out in the coolness of some overflow water from the beds.

This morning it was the young Gopher snake (above), about a foot long, but only as big around as a finger. Gophers are common in our yard, but I always admire how their yellow and chocolate pattern shifts subtly from head to tail, from yellow-on-brown to brown-on-yellow. You can’t tell where the change-over happens, but the tail is positively different from the head.

<< The change-over zone (Photo A.Shock)

Unfortunately, this beautiful pattern is the reason so many gopher snakes are killed by fearful people: it’s reminiscent of the diamond-pattern on rattlesnakes. Gophers (or bull snakes) are especially welcome here as efficient rodent predators; our part of the Phoenix area has been plagued with roof-rats for a decade or so.

This young’un in the photo above saw me before I saw it, and hid its head under an orange leaf, leaving the full length of its boldly patterned body out in the open. Here it is, sneaking slowly away in the hopes the looming predator (me) doesn’t notice.

Quite a lot of penguins

It’s still hot in Phoenix, although less hot than formerly, so here’s a cooling black-and-white-and-gray vista to cool the eye.

These King penguins (Aptenodytes patagonicus) are amassed on South Georgia Island, located at 54〫S in the fearsome southern Atlantic ocean.  There are tens of thousands of them on this breeding beach.  Most of the individuals in this photo are adults — males are larger than females, but the sexes are similar in plumage — but note the so-called “oakum-boys” in their shaggy browny downy chicky plumage standing around waiting for semi-digested krill to be delivered by mom or dad. (Photo A.Shock)

Etymology

According to this site the term “oakum boy”, referring to King penguin chicks, is explained this way:

“The old sealers called them the oakum boys as they looked like the rolls of oakum used for caulking ships. Oakum was a loose fibre got by picking old rope to bits, sometimes, even rope that had been used to hang criminals. Convicts or paupers often did this work. (Ever heard the expression money for old rope?). The word oakum comes from the old english (before 1150 AD) acumbe, literally off combing. The word comb comes from old saxon. Caulking was the stopping up of the seams of ships using oakum and a waterproofing material like tar.”

Key to the Goldfinches Spot the Bird

SPOILER ALERT!!

Here are the three goldfinches in yesterday‘s Spot the Bird, highlighted in color for ease of viewing.

Spot the bird: Lesser goldfinch fressing

We planted sunflowers in the garden for the goldfinch; it seems to have worked.

Now that the flower heads are mature and seedful on the stalks, the bushes are crowded with Lesser goldfinch. There are lots more flowers in bloom, which will keep the hungry finches supplied into the fall or even early winter. The thin stems don’t seem to support the weight of larger birds, so the lil yellow finks have the crop to themselves. The LEGOs (LEsser GOldfinch) also love herb seeds, “Mexican Hat” (Ratibida columnaris) seeds, and the nyjer thistle we hang for them from mesh feeders. They are cling feeders, and often feed hanging head-down.

Here are a couple of photos from this morning of male and female Lesser goldfinch (Carduelis psaltria) chowing down on the seeds from the ripe sunflowers. In the top photo is an easy-to-see first-year male, nearly completely molted into his adult male plumage. The picture to the left is a “Spot the Bird” since the little bodies blend in so well, due to both color and size; I counted three goldfinch, two males and a less colorful, olive-y female, but there could be more. I put up a big file, so please enlarge it to see better. (All photos A.Shock)

Lesser goldfinch are the default goldfinch of the western US. If you live east of the 100th parallel (roughly), you’ll have the dapper American goldfinch (called Carduelis tristis on account of its “sad” vocal note), who is slightly larger and yellower and who uses its noticeably pink, conical bill to open seeds. Lawrence’s goldfinch (C. lawrencei, no points for etymology there) is the most uncommon of “our” goldfinches; most of the population lives in arid California grasslands, but they roam a bit, and a few show up in Arizona and other western states most years.

Etymology

According to Choate’s American Bird Names, the genus Carduelis is derived from the Latin word carduus, thistle, goldfinches’ favorite food the world around. The species name, psaltria, is from the latin word for “lutist” because of its musical singing. They do have a bright, cheery song, lengthy for such a small bird — LEGO is the smallest of the three North American goldfinches — and they chatter delightfully in groups in the palo verde trees after the morning feeding session is finished. If you have a tough time keeping the species name “psaltria” in mind, try this mnemonic: psaltria sounds a bit like (although is totally unrelated to) “paltry”, which means small.

By the way, there is no correlation to bird body size and song duration or (relative) volume; it’s just humorous when a little beak opens up and lets out a long stream of warbly, chatty notes. The Winter wren is another small bird with a mighty song.

We interrupt this flamingo…

…to bring you a tiny owlet.  From Pink to Dink, with hardly a blink.

Friday morning, I came home from delivering E to campus, and blissfully opened the back door to let in the first blast of coolish late summer air.  Instead of the usual morning quiet, the back yard was chattering with angry bird sounds: MOB!  Two Curve-billed thrashers, three cactus wrens, one Costa’s and two un-ID’d hummers, a verdin, a handful of Lesser goldfinch, and a couple of Gila woodpeckers, all shrieking in the upper branches of the messy African sumac right outside the bedroom door.

I stood under the canopy of snaggly twigs and miscellaneous branches for a while, with binox, until I saw the reason for their agitation: the Real Cranky Owlet.  A tiny, tiny owl, with a round head, staring down on me with enormous outrage.  I ran in to get binox and camera, and when I got back outside, it was sitting there still radiating high dudgeon.

It took a bit of hunting to find a window through the leafy snarl, but I finally got the owl in clear view.  At first I thought: it’s a recently fledged Western Screech Owl, too young for cranial tufts (ie, “ears”), wedged up in the twigs, trying to pretend it hadn’t been spotted by half the shouting avifauna of the yard, and one quarter of the interior mammals.  I’d recently been hearing a WESO calling at night in the yard, and we get them around here occasionally (well, they’re probably here all the time, but we hear or see them occasionally).  It was a likely candidate.

<< radiating high dudgeon

But… I looked again, without my binox: it was clearly not a screech owl — the bird was SO TINY!  As any birder will tell you, size is one of the hardest characteristics to judge in the field, and an easy place to go wrong. Comparisons are invaluable. The thrashers mobbing it were considerably bigger than the owl; it was about the same size as the Cactus wrens, although in a vertical format, rather than horizontally arranged like the wrens; it was approximately sparrow-sized.  There’s only one owl that dinky, in the desert or anywhere: the Elf owl (Micrathene whitneyi, en français chevêchette des saguaros, en español tecolotito anano).  The supercilious white “spectacles”, the reddish blotches on the breast, the size of the eyes in the smallish head: it was an Elf owl in our yard! I was able to get a couple of poor snapshots — tough light to boot — which I’ve posted here, magnified.

Like the Western screech owls, Elf owls may be in the neighborhood regularly; we live in an “older” (by Phoenix standards) subdivision with naturalized desert landscape, including mature saguaros with woodpecker holes.  But I hadn’t heard an Elf owl or seen one around here, and believe me, it wasn’t for not listening, or not looking in every saguaro hole I know about. So, since the Elf Owl population in our part of the state is seasonal, it’s also possible that this individual could be a migrant, moving out of its breeding area to its wintering zone, passing through our yard.

The sumac probably seemed like a good day roost.  But, unfortunately, it turned out there were not only hecklers, but a paparazza, and the tiny owl flew a few yards to lose itself in the denser, thorny canopy of the nearby Texas Ebony.  The hecklers followed, but I didn’t. (All photos A.Shock)

More Mightier Pink

The last post, on Roseate Spoonbills, was mighty pink. But I have to admit Flamingos are pretty dang pink, pinker even than Roseates. This is because they are bigger, and their entire neck and head are flaming salmon. And these two are American Flamingos (Phoenicopterus ruber), who are among the pinker of the world’s six flamingo species.

Flamingos have a propensity for extreme environments: highly alkaline lakes in Africa, the high Andes, Florida, rugged volcanoes sticking out of the middle of the Pacific Ocean. Here’s a pulled back shot of the area where this group of flamingos were wading:

I love the setting because it’s both peaceful and bizarre: a big volcanic hill covered with lava and dry thornscrub, bright pink preposterous birds with upside down heads, and giant cactus. Only in the Galápagos.

<< Flamingos in the Galápagos (photo A.Shock)

Another admirable thing about flamingos is their name. In Italian it’s fenicottero, derived from the genus Phoenicopterus, “crimson-winged”, which is the latinized version of the modern Greek name for the bird as well: Φοινικόπτερο; French, flamant rose; and Spanish, flamenco. The connection between the name of the colorful birds, which perform lavish, mannered dances, and the national dance of Andalusia is reportedly still debated; which came first — the dance or the name?

Roseate spoonbill

That’s all.  Just… Roseate spoonbill.

Platalelea ajaja is a fairly large hot pink wading bird with knobby gray knees and a spoon-ended sifting bill which it swings side to side in the water while feeding.  They tend to be gregarious, and seeing a bunch feeding together on mudflats is a fine pinksome sight.

<< This solitary one is on the muddy mouth of the Rio Tárcoles on the Pacific coast of Costa Rica.  Mighty pink ain’t all about the flamingo.

There are other spoonbills, world-wide.  Most hang out in estuaries.  The one in the distant shot below is a Royal spoonbill (Platalea regia), photographed on the Manawatu River Estuary on the Tasman Sea coast of the North Island of Aoteaoroa (New Zealand).  Check out the Wikipedia article on this bird; it’s got a fantastic nuptial crown of white quill-like erectile plumes, hence its regal moniker.
