Desert Dove-o-rama: White-winged doves

Arriving in the spring, they lurk like vultures for weeks on the crowns of blooming saguaros, waiting for the flowers to swell into fat green fruits.  When they do, the White winged doves (Zenaida asiatica) rip them open with their strong fruit-ripping beaks, exposing the sweet red fruit and feasting greedily.  Sometimes several doves will stack, treading clumsily on one anothers’ backs, vying for access to their favorite food.

“White wings” are big doves, and during their breeding season, which are the hottest and driest months of the Sonoran Desert year, they rely heavily on the fruit of the saguaro for food and water.  So heavily in fact that in this habitat biologists consider them “saguaro specialists”.  In other parts of their large range, which includes the Caribbean and parts of Central America, they are agricultural freeloaders, and vast flocks of them take advantage of bountiful farmland for food and roosts.  Here they are considered “tropical doves” by ornithologists and “pests” by farmers. As such, they have been hunted energetically, and their population numbers are subject to wide swings throughout the year and decades.

This pesky mooching aspect of this big dove is not hard to imagine: they are agressive and a bit greedy at the yard seed feeders, and will lower their heads and charge at smaller doves, like their “cousins” the Mourning doves, making a hoarse hoo that’s the columbid equivalent of a growl.

But perched picturesquely on top of a fruiting saguaro against a desert blue sky, their frequent “who cooks for you” call means summer to me, and a welcome sign that the desert cycles are intact and thriving.

Festival of Desert Doves: the Other Collared Dove

The Eurasian Collared Dove (Streptopelia decaocto) has an agenda well-befitting a Columbid: “Must Colonize New World.”

Actually, it started before that, and a lot farther east: a native of central Asia, the Collared Dove had populated Europe as far west as Great Britain by the 1950s.  By the early ’80s, a population had taken hold in Florida, likely coming from the Bahamas where they also had been introduced (or escaped captivity) in the 1970s. From there, the large doves filled the southeastern US, and have been spreading inexorably west and north.  The first documented report of the species in the state of Arizona was in Eager, AZ, on March 6, 2000, and they were regularly sighted in Maricopa County by the end of the same year.

As mentioned in a previous post, they’re quite similar to the African Collared Dove (which used to be called the Ringed Turtle Dove), but they’re bigger, and a darker beige, and have different vocalizations.  In the Phoenix area and over much of Arizona, Eurasian Collared Doves have become quite numerous — on some days I would ungenerously call them a pest in our yard — and a few theories exist as to why they’ve spread so rapidly.  One is that they fill a niche left empty by the extinction of the Passenger Pigeon  (Perhaps in the Northeast U.S., but I’m not so sure that applies to the desert regions?).

Like the African Collared Doves, they show a disturbing willingness to become tame, and quickly learn  to fly down to empty feeders when they see someone coming out with a bag of birdseed.  I’ve caught them lurking on top of my studio — their toenails clicking on the roof, their pink foot skin glowing hazily through the translucent plexi panels — as if lobbying for the filling of neglected feeders in a kind of inexorable zombie-like way.  They’re hard to miss since their arrival is a dry noisy wing flapping, the thump of a hard landing of a big heavily-wingloaded airship, and the inevitable repetitive hoo-ing and gibbering that follows.

Meet the Hair Hen…

This is the Hair Hen.  Actually, there are two; we call them both the Hair Hen because we used to not be able to tell them apart.  Now we can: one has two kits, the other has three.

This is a picture of the three-kit Hair Hen.  She lives under the Mexican Fan Palm in the back yard, where she spends much of the day.  She talks to the kits and keeps them in line with a soft churring purry noise, so we know they’re there even when we can’t see them in the deep thicket of thorny fronds and shaggy trunks.

We’ve been seeing the two-kit hairhen and her brood, but this evening our neighbors called and alerted us to the three-kit hairhen: the furry family was headed our way.  Sure enough, a minute later they were strolling along the pool deck, learning how to drink from the pool by putting their paws on the plaster under the tile and leaning way over.  (Hey! be careful — no lifeguard on duty…)

This may or may not be the same hairhen who threw three kits last season; we can’t know for sure.  (If she is the same one, she now has a chip in the tip of her right ear).

How many raccoons is too many?

My Hoodia Stinketh

For a few days I’ve been whiffing a whiff, which has caused me to search for the dead mouse in my studio.

Then, I noticed the Hoodia is blooming.  It sits on the shelves right outside the work tables.  That window is always open, being the draw-source for the swamp cooler air.  So the stinkitude of the big radar-shaped flowers was being propelled directly into my work area.  Here’s a picture of the offending vegetable; you can see glaze bottles and a banding wheel through the glass behind it.

The genus Hoodia is comprised of cactus-like stem-succulents whose flowers are pollinated by flies.  To attract flies, it is desirable to smell like carrion.  So like their cousins Huernias and Stapelias, Hoodias put out flat flowers the color of puffy, pus-streaked dead flesh with a blood-dark target center.  They smell convincingly of rotting meat, especially in warm weather.

Does it work?  Yes; there are a number of flies buzzing inquisitively around the plant all day.  And — is it possible? — this morning as I was hanging out laundry to dry, there was a turkey vulture circling low, right over the studio perhaps aiming its pervious nostril at our garden…

This specimen blooms heavily around the middle of June every year, as long as it gets enough water in the growing season.  It is labeled Hoodia gordonii, of appetite suppressant fame, it having been observed by ethno-anthropologists that the indigenous people of the Namib use Hoodia to relieve hunger.  Hoodia are not cactus at all, but members of the subfamily Asclepiadoideae, and so are related to milkweed.

Festival of Desert Doves: African Collared Dove

The desert suburbs of Phoenix are Columbid-rich, that is, there are many species of doves and pigeons.  Yesterday I was putting out seed in a neighbor’s gravel drive just before sunset.  The area is quite open, and at that time of day it fills with fat, free-loading doves and pigeons who are used to being fed there and then: after only a minute, there were 30 birds chowing down, their heads bobbing up and down rapidly like sewing machine needles, almost all of them Columbids.  I counted six species both native and exotic — all the species regularly seen in our neighborhood and most seen regularly in the Phoenix area at this time of year: Mourning dove, White-winged dove, Inca dove, Eurasian Collared Dove, African Collared dove, and Rock Pigeon.

There was only one African Collared dove (Streptopelia roseogrisea).  This species, like its close relative the now-abundant Eurasian Collared dove, is an exotic.  But unlike the ECDO, which was introduced in one place and then spread itself across the nation, the African Collared dove (or Ringed Turtle dove) was originally released very close to here but hasn’t spread widely, even in the Phoenix area.

The plumage of the two exotic doves are somewhat similar: both are beige and have a black crescent on their neck.  They can be hard to tell apart, until you get the hang of it.  The African is a smaller, paler dove, almost white, with a gentle two-note call that sounds like the chorus from the Rolling Stones’ “Sympathy for the Devil”: “Woo-HOOooo!”  The larger Eurasian is slightly darker in plumage and has a hoarse three-note call with the emphasis on the middle note: “hoo-HOO-hoo” which it utters incessantly.

Our neighborhood hosts a small population of the daintier African Collared dove, and one of them spends most of its time mooching in our yard and our neighbor’s yard.  Because of its habit of snarfing up seed rapidly, packing it into its crop and then flying off to digest at leisure, we’ve named it Hoover, like the vacuum cleaner. (Hoover used to have a mate, Eureka, but she’s not around these days).  These birds are quite “sweet”: by that I mean they are not very afraid of people, unlike the other doves which all have a proper wariness towards humans.  They will fly right down and land on the ground at your feet if they think seed is to be had.  Not surprisingly given these behavior traits, there has been debate among ornithologists as to how domesticated this species (or variety) of dove is, but currently it’s enjoying full species status.

Springtime do-over in Sedona (with Bonus Wild Hen nidification)

We missed some of Spring in the desert this year, so last weekend we went in search of it under the Mogollon Rim: Sunday found us hiking along the West Fork of Oak Creek in Sedona.  It’s one of the more popular trails in that popular area, and at times it’s mobbed by clusters of sweaty Phoenicians looking for a quick cool-off up in the oak pine red rock country.  But the weather in the desert has been cooler than seasonal, and although we certainly weren’t alone on the path, the trail wasn’t as crowded as we feared.

The day couldn’t have been more beautiful — Oak Creek Canyon at that point is a mile high (literally) so it’s still spring up there, with lots of showy color.  Both Scarlet and Yellow Monkey Flower (Mimulus cardinalis and guttatus), Golden columbine (Aquilegia chrysantha), and Western spiderwort (Tradescantia occidentalis) were at their peak. Columbian monkshood (Aconitum columbianum) and Deers-ears (Frasera speciosa) were just beginning, as were the False Solomon’s seal (Smilacina sp).  Butterflies abounded — both on flowers and on ammonia-rich heron-wash smears on the gravelly banks — and the air was lively with swallowtails, skippers and sulphurs, and others I don’t know.

The local birds were lively and showy too, the males singing and holding territory: Lazuli bunting (Passerina amoena), Black-headed grosbeak (Pheucticus melanocephalus), Western tanagers (Piranga ludoviciana), and Red-faced warblers (Cardenlina rubifrons) were among the colorful singers, while Cordilleran flycatchers (Empidonax occidentalis), House wrens (Troglodytes aedon), Plumbeous vireo (Vireo plumbeus) and the ethereal-voiced Hermit thrush (Catharus guttatus) were vocal but plainer of plumage.

Now, I admire a little brown bird as much as anyone — the House wren is a delight to watch, singing so hard its little barred tail vibrates — but it’s tough to not be swept away by the sight of tiny woodland jewels like Red-faced warblers, who were numerous and singing, or the Painted redstart (Myioborus pictus) who was foraging quietly and intently as if he had nestlings and a mate to feed.

To the right is a page of the day’s birdlist, sketchily illustrated on the fly with really tiny thumbnails of a couple of the brighter species.  (I’ve been honing down a back-packing sized watercolor kit, and it’s coming along well, although I haven’t yet gotten the paints pared down to an Altoids-tin, since Jerry’s Artarama is still out of empty half-pans). The bird-list is small-scale, too — in a Moleskine journal just 3.5×5.5″.

The Broad-tailed hummingbirds (Selasphorus platycercus) were zizzing around fussily, sometimes more easily heard than seen, but we lucked into looking up at just the right time to see this Hen settle onto her nest on a bough directly over the trail.  Check out her clever lichen-camo, and how it blends right down into the lichen-covered Big-toothed maple branch!

The Phoenix-Sedona round trip with an eight-mile hike in the middle makes for one long day, but even so we came back refreshed and renewed, glad to have a cooler option when the desert is too hot to hike.  Graduated seasons are one of the nicest things about living in a state with delightfully drastic topography.

One of the best things we DIDN’T see in New Zealand…

…was a Ruru, or Morepork (Ninox novaeseelandiae).

It’s NZ’s only remaining native owl (the Laughing owl was last recorded in 1914), and is fairly common in many habitats, even parks and gardens, but is especially numerous in tracts of native bush.  We heard them several places, mostly in the Kauri Forest while on a night walk looking for Kiwi.  They whinny and whoo and screek, but their main call is, not surprisingly, “More-pore” repeated frequently.  If you live where there are Inca Doves, you know what a Morepork sounds like.  Inca doves’ call is usually transcribed as “whirl-pool” or “no-hope”, but in pitch, frequency, and tone, it’s very much like the owl’s call.  The Māori name, Ruru, is also onomatopoetic, as is the Australian name, (Southern) Boobook.

Ruru is a relatively small (approx 10″ ht), long-tailed owl that takes a range of prey but specializes in nocturnal insects like weta (large crickets — really large crickets!), huhu beetles and moths.

Gamboling Gambel’s Quailets

In our area, the first Gambel’s quail chicks of the year usually start showing up in early May, clustered around their parents under the mesquite trees in the yard, pecking expertly at the ground like the precocial youngsters they are.  This year, since we weren’t around then, we missed the “nebula phase” of their development — when they’re so small and move so fast that it’s hard to count them: a streaky brown cloud of down orbiting the adults like electrons, running everywhere because their legs are so short.

Now that we’re back, the feeders are full again, and the parents are bringing their broods around.  For the past two days there’s been a family of six cleaning up nyger thistle that the frenzy of fressing finches let fall from the front mesquite feeder: two adult quail and four chicks.  The chicks are still quite young, but no longer downy — adolescent really, and they’re beginning to get little nubs on their foreheads where their topknots will grow in.  They are still cryptically colored buffy-streaky so that they’re nearly invisible against the soil in the dappled sunlight let through by the mesquite’s tiny compound leaflets.  Papa usually stands watch as the family feeds, which they do at a more leisurely pace than when it’s the adults alone.  This may be a clutch incubated in the spiky tangle of our fan-palm, where a hen successfully raised a brood of 9 last year.

Normally I’d snap a photo of the family scene above.  But because I can’t get a decent picture through the reflection-hazed windows looking out onto the feeders (I’ve tried!), and going outside would start the whole shebang to flee, I thought I’d sketch from life (above).  I’m just finding my way around watercolors again after a very long absence, and haven’t managed to loosen up as much as I’d like — at this point, I seem to produce tinted drawings, rather than acheiving a freer painting style.  One reason for that is that it’s such a different process than capturing “birdness” in the broad, unblended swatches of opaque glaze color, which is what I normally do, as in this Three Star Owl male Gambel’s quail wall tile pictured to the right.

With a couple of exceptions, I haven’t really posted much about something that’s very plentiful in Aotearoa/NZ: amazing landscapes.  Although there’s lots and lots of pasture land, crammed with sheep and cattle and non-native trees and grasses, the islands have a plentiful supply of charming vistas, rugged and awesome terrain, and outright wilderness.  All of which is packed into what seems to people used to the sprawling American West to be on a convenient and compact scale.

Because of the high latitudes, mountains don’t need to be Rocky-Mountain high to be snow-clad, and towards the south, bush-line is usually just over 1000m, or 3400 feet in elevation.  There are places you can be hiking a glacier and look down onto a surfing beach.  The vegetation reflects this variety, and where native growth still exists, it’s exotic and extradordinary: temperate rainforest thick with tree-ferns, sub-tropical bush with cabbage trees, high-latitude Nothofagus forest, low-growing alpine mats.  We even found some stray prickly pear in bloom around the warmer spots in gardens on the volcanic lakes area, and the occasional Agave americana in landscapes.

Periodically I’ll post a sampling of some of the places we saw.  Here’s a few, with their captions beneath each one:
