Refugees

On this hot, dry, and windy June afternoon, the chickens were restless. Despite my efforts to make them more comfortable—watering patches of dirt for bathing, setting out a bowl of iced apple juice—they wanted more relief and knew where to find it. One by one they hopped up onto the porch and stood by the door, looking longingly through the glass. 

It was uncomfortable for me, too, so I went back inside, locked the dog in the bedroom, and invited the girls into the house. They ate and drank from Sibella's bowls, scavenged the kitchen floor for crumbs, and visited me in the study as I worked at the computer. Pearl was muttering to herself a lot and couldn't seem to get comfortable on my lap. Only when I noticed her trying to mold a nest out of the folds of a serape draped over the dog's chair did I realize that she had an egg to lay and needed to return to the coop.

With bowls of frozen peas and corn as bait (lightly thawed as a cool treat), I lured the girls out the door into dim orange light filtering through a dense column of smoke. Fragments that were once grass leaves, now carbon ghosts, spiraled down to land on the deck. The plume from the Monument Fire, 22 miles to the west on the southern end of the Huachuca Mountains, had been drifting across our neighborhood since yesterday afternoon. In less than an hour it had increased so dramatically in breadth and density that it sent a jolt of fear through me. I hurriedly shooed the chickens into their run, grabbed my car keys, and headed west to see how far the fire had spread.

The Monument Fire in the Huachuca Mountains, as seen from near Bisbee
It was an eerie scene. Smoke billowed up from a broad front on the southeastern corner of the mountains, reducing the sun to a glaring red eye. From my distant vantage point I could see no flames or firefighting activities, but it was clear that the fire was burning the oak woodland and pine-oak forest homes of many of our favorite birds and approaching the houses of people we know.

The order came down this afternoon that residents of the southeastern canyons of the Huachucas would need to evacuate. Human residents will take refuge in the homes of friends and relatives, motels, bed & breakfasts, etc. Livestock will ride out the fire at nearby ranches. Untold numbers of wild creatures will find no sanctuary while the fire rages. Many will not survive, and many that do will have nowhere to return to once it's out.

Residents of the Chiricahua and Huachuca mountains have reported wild refugees fleeing the fires. Bird activity around the town of Portal in Cave Creek Canyon has been very high, and a colleague who lives in the Huachuca foothills reported seeing a desperate-looking Black Bear at his backyard water feature as he was preparing to evacuate.

A hungry Western Tanager
We live too far from the Huachucas or Chiricahuas to expect fire refugees, which is a small blessing. We already have our share of drought refugees, birds and other wildlife desperate for food and water.

This spring, unprecedented numbers of Wilson's Warblers, Western Tanagers, and Black-headed Grosbeaks swamped feeding stations and concentrated along the San Pedro River seeking what little water and food were available in this parched landscape. In our yard, Mule Deer stripped a young mulberry tree of most of its leaves, and Javelinas (a.k.a. Collared Peccaries) ate all the new growth from our few prickly pear cacti that survived the brutal February cold snap. Rock Squirrels were eating all the seed, fruit, and peanut butter dough we put out for the birds, so we began live-trapping them for deportation well beyond the edge of town. We've relocated eleven so far. Cages, netting, and vigilance are the only reasons any of our vegetables have made it this far.

The drought and fires extend well into Mexico, which may be responsible for the appearance of a number of local and regional rarities: a Yellow Grosbeak in Ash Canyon, a Berylline Hummingbird on the San Pedro River, Lucifer Hummingbirds at several unusual locations, and various eastern "vagrants" at others (possibly stranded, unable to find enough food to fuel the next legs of their migrations).

Drought is such a slow-moving disaster that it doesn't make headlines until fires break out. Climate change, too, creeps so slowly that Big Fossil's lobbyists and the politicians they own have had plenty of time to quibble, bluster, and stall, effectively thwarting efforts to avert this disaster in the making. It beggars belief that anyone can continue to scoff in a year of record-breaking storms, floods, droughts, and fires, yet some do.

The past year has fulfilled climatologists' predictions of greater extremes, including wet summers in the Southwest followed by rainless winters and springs. This is a perfect recipe for devastating forest fires. Summer rainfall stimulates abundant growth of grasses, annuals, and shrubs that, once dried, provide ideal fuel, and winter/spring drought creates ideal conditions for catastrophic fires.

It's vitally important to understand that fire is an essential element in many western forests. Southwestern forests in particular need periodic fires to recycle the nutrients in leaf litter and other debris that doesn't decompose in the dry climate. Keeping fire out of these forests is a recipe for disaster, yet that's exactly what we've been doing (first incidentally, then actively) for more than a century.

That said, the fires currently burning are not the kind we need. Natural fires are sparked by lightning from the first dry storms of the summer "monsoon" and usually quickly extinguished by the rains that follow. The current fires are all of human origin, ignited weeks ahead of the rains during our driest, hottest, and windiest time of year. This means weeks of valiant efforts to manage the fire, keep it away from structures and ecological jewels, and "encourage" it to burn in a way most conducive to forest hygiene. Weeks of flames sweeping and/or creeping through our "sky islands."

This is all I can bear to write tonight, but there's more of the story to tell. I'm going to go watch the moon rise and think about Part 2.

Update: I just heard from a friend that the fire jumped Hwy 92 late this afternoon, and that a number of structures have already been lost.

Anna's in the snow



A male Anna's visited our hummingbird feeder during this morning's mini-blizzard. He could barely hang on as the feeder swung in the wind and snow pelted his face. Not wanting to make his morning even more stressful, I waited until he left to put out fresh, warm sugar water.

It's been a grim winter for Arizona's hummingbirds. Many died in the Big Freeze of 2011, and many others had to be rescued. Hummingbirds in Tucson and Phoenix, where temperatures rarely stray below freezing, seemed more affected than those wintering at higher elevations. Here at 5000 feet in the foothills of the Mule Mountains, our two or three Violet-crowneds and handful of Anna's managed to ride out the January cold snap, but most disappeared after the all-time record low on the second night of the Big Freeze (0° F./-18° C.).

The following morning's weather was much improved, so I'm hoping that they rode out the worst and departed as soon as possible, as hummingbirds wintering in much colder climates have been observed to do. We're still hosting at least one female Anna's in addition to this male, but there's been no sign of a Violet-crowned since the first day of the freeze (at 8 a.m., during the second feeder change of the day). Even with a bustling clientele of Northern Cardinals, Pyrrhuloxias, Green-tailed Towhees, Gambel's Quail, and many more, the feeding station seems forlorn without an occasional flash of violet blue.

It will be weeks before I can tell how much of our hummingbird garden survived, but in the meantime I'll be escaping waaaay south of the border (Belize and Tikal) for a couple of weeks, leading a birding and natural history tour for SABO.

Panic at the playa

It was early afternoon in the southern Sulphur Springs Valley, and the last few hundred of Arizona's largest flock of Sandhill Cranes were returning to their roost at the playa lake at Whitewater Draw Wildlife Area after breakfasting on waste grain in nearby farm fields.

Suddenly, chaos erupts as thousands of cranes take to the air in seconds!

Normal crane chatter rises to a deafening clatter as a multitude of voices raise the alarm.

What could have caused this mass hysteria?

The answer comes gliding through, slicing the panicked flock in two: A Golden Eagle, one of the few predators an adult crane has to worry about.

This scene plays out almost every winter day at Whitewater Draw Wildlife Area, one of the lesser-known jewels in Arizona's birding crown.

Portrait of a worried dad

This male Lesser Goldfinch has every reason to look worried. He and his mate have a very late nest in the plum tree by our patio, so when I heard an unusual amount of mewing and chipping out there I went outside to see what was going on. The goldfinches were eyeing a Curve-billed Thrasher making its way through the thick foliage toward the nest. Our thrashers don't miss many meals, so I didn't feel too guilty distracting it with a few harsh words ("Hey! I hear your sister is dating a starling!") and convincing it to leave. The finches stayed exactly where they were, still on high alert. Probably not a good idea to go straight back to a nest when the predator might still be watching.

Stokes Field Guide to Bird Songs: Western RegionLesser Goldfinches are one of those those birds whose voices are so delicate that even their harshest calls lay as sweetly on the ear as a song. More sweetly than their own songs, in fact, since these consist largely of other birds' calls. One of our neighborhood males sings rapid-fire songs that consist mainly of flycatcher calls: Ash-throated, Brown-crested, Vermilion, Say's Phoebe, Cassin's Kingbird, Western Kingbird, Western Wood-Pewee. A male that lives in Miller Canyon does a great impression of the "rubber duck" call of the Sulphur-bellied Flycatcher. The phrases go by so fast that the bird may be four or five species further along by the time you can say, "Hey, wasn't that a...?" --SW

September surprise


So, yesterday morning I was out on the patio supervising the chickens' free-ranging activities and watching the show at the feeders when I notice this hummer sitting on the far feeder across from a Rufous/Allen's...


Something about it set sirens off in my head. As the Rufous/Allen's backed away, the other bird raised its head in response...


...revealing the long, curved bill of a Lucifer, the first confirmed in our yard in the nearly 15 years since we moved in and put up the first feeders.


A Field Guide to Hummingbirds of North America (Peterson Field Guides)The species nests here in the Mule Mountains, so hopefully we'll see more of them next season now that this lady has found our garden and feeders. With a Calliope that Tom spotted later in the afternoon, our 48-hour hummingbird tally came to a whopping 8 species: Broad-billed, Violet-crowned, Black-chinned, Anna's, Lucifer, Calliope, Broad-tailed, and Rufous (mostly "Rufous/Allen's," but most of the juvenile males are identifiable to species by their tail feather shapes).

A lovely creature however you pronounce it

The lush monsoon grasses are setting seed, and waves of Lazuli Buntings from the north are feasting. This gorgeous male was among many at Whitewater Draw Wildlife Area yesterday morning.

The Sibley Field Guide to Birds of Western North AmericaWhen you see one of these, what do you say?

"Look! There's a La-ZOO-lee Bunting!"?

"Why, I believe that's a LAZ-oo-lie Bunting!"?

Or maybe "Check out the the little blue dude!"?

Moon of the Giant Asparagus

Palmer Agave, Agave palmeri
Huachuca Mountains April 29, 2009

Every year I'm caught off guard by the first agave bloom stalks. The first ones appeared at the end of April, and it seems like they're all over now. This signals the beginning of the end of the plant's life, as it puts everything it's got into its massive flower stalk, but the nectar and pollen are a boon to nectar bats, hummingbirds, orioles, doves, and insects of many kinds. —SW

P-Dogs are in da howz!


A little good news amongst the grim:

Decades after federal programs extirpated them from the grasslands of southeastern Arizona, Black-tailed Prairie Dogs have returned to their historic home with a little help from their friends in the Arizona Game & Fish Department and Bureau of Land Management.

According to the AGFD press release, 74 BTPDs captured at Ted Turner's Ladder Ranch in New Mexico were released on Las Cienegas National Conservation Area on October 7. It's ironic that the transplants came from over 200 miles away when a small BTPD town persists less than 40 miles from the release site just across the Mexican border from Coronado National Memorial (thanks to a friendly rancher), and the largest remaining colony of this species in the world is less than 150 miles away in northwestern Chihuahua (where the PD photo above was taken).

P-dogs aren't canines, of course, but rodents in the same family as fluffy-tailed feeder raiders. Their sharp alarm calls, actually a complex and adaptable language that transmits detailed information about goings-on in their community, earned them the name that, given Euro-American culinary taboos against dining on dogs, probably saved them from becoming favorite targets of hungry pioneers and greedy market hunters.

They would have been an abundant food source, too. Two hundred years ago, BTPD "towns" numbering in the thousands to millions of inhabitants were found from Texas to Montana. The intensely social nature that inspired wonder in early explorers such as Lewis and Clark (who sent a live specimen back to President Thomas Jefferson) doomed them when cattle replaced the great herds of bison, pronghorns, and elk. In the late nineteenth century, newly-minted cattle barons who saw the colonial rodents as competitors taking food out of the mouths of their stock persuaded the government to launch a campaign of extermination that persists to this day. In their heyday, the shooting and poisoning efforts resulted in mountains of dead PDs displayed as trophies.

This wanton destruction was a disaster not only for the dogs themselves but for entire grassland ecosystems. Prairie dogs are keystone species, altering their habitat in ways that benefit other animals such as Ferruginous Hawk, Mountain Plover, Burrowing Owl, Pronghorn, American Bison, the critically endangered Black-footed Ferret, Kit and Swift foxes, and over a hundred more common species. The p-dogs' range management activities include suppressing woody vegetation, cultivating tasty and nutritious forbs, recycling nutrients from their underground latrines, and providing protected nest and den sites in landscapes where shelter is normally scarce. The dogs' elaborate burrow systems also significantly enhance recharge of aquifers essential for irrigated agriculture and other human activities.

Their underdog status is just one factor that earned prairie dogs a special place in our hearts. Thirty years ago, as director of the Fort Worth Nature Center and Refuge in Texas, Tom (who really ought to be writing this post) launched a project that successfully introduced Black-tailed Prairie Dogs to the refuge's large bison enclosure. Actually, he tried to introduce them to a large fallow pasture adjacent to the "buffalo range," but the p-dogs had other ideas. Like characters in some prison break movie, they dug under the sunken fencing of their temporary pen, crossed the road, and made themselves at home right in the middle of the bisons' favorite grazing area. Over the next few years the dogs became a favorite attraction with the public as well as one of Tom's passions. Their behavior and ecology are complex, fascinating, and easily observed, not to mention that they're civilized creatures that don't emerge from their burrows until well after sunup or stay out past sundown.

This history with prairie dogs prompted us to attend a public meeting held several years ago by AGFD to explore the possibility of reintroducing BTPDs into southeastern Arizona. The opposition was out in full force, repeating the same kind of easily debunked myths you hear at wolf meetings. (So cows and horses break their legs in prairie dog burrows? Have you ever personally seen this happen? No? Then maybe you can tell us why the early explorers didn't report herds of bison limping across the plains?) Naturally, Tom and I stood up for PDs at that meeting, but given the controversial nature of the subject and the glacial speed at which government bureaucracies move, we didn't expect to see any meaningful progress for a decade or more. The announcement of preparations for this week's reintroduction came as a thrilling surprise, and I wish we had been able to donate a few volunteer hours to the effort.

So what do we have to look forward to as BTPDs establish themselves in their new digs? Birders will delight as Ferruginous and Red-tailed hawks and Golden Eagles cruise the colony trying to pick off unwary residents, Burrowing Owls move into abandoned burrows, and longspurs and Mountain Plovers spend the winter foraging in the town's wide open spaces. Children on school field trips will learn about the social life, ecology, and history of prairie dogs, and both residents and tourists who would never have thought to visit Las Cienegas National Conservation Area will stop in for a peek at these remarkable mammals. If left alone, the town could get big enough to support Black-footed Ferrets, perhaps even some raised right here in Arizona at the Phoenix Zoo. A few ignorant people will complain (loudly), but with positive feedback to AGFD and BLM from birders and other enlightened members of the public, these agencies may have the support they need to expand reintroduction efforts to the Sulphur Springs and San Pedro valleys.

In 1968, Audubon magazine published an article titled "Dark Days in Dog Town" about the federal poisoning program. Here's hoping that those days are over and a brighter, more rational day is dawning in our relationship with prairie dogs. --SW

Kiss kiss, bang bang

Mid-June is a perfect time for this Zooillogix post on kissing bugs. These stealthy stowaways emerge each summer from our local White-throated Woodrat (pack rat) nests (of which there's one under our bathroom floor) to invade southern Arizona homes in search of fresh blood.

Kissing bugs (genus Triatoma) are on a very short list of invertebrates that we terminate with extreme prejudice whenever and wherever they're encountered. Even bark scorpions get a pass if we find them in remote parts of the yard, but kissing bugs always get swatted, stomped, or crushed in a handy paper towel. And we do keep those paper towels handy, because offing them can be a thoroughly disgusting experience. Even if they're not bloated from a recent blood meal, they produce a powerful defensive stink like other members of their suborder, Heteroptera. You do NOT want to get that nauseating reek on your skin or clothes. There are three species in southern Arizona, but I never pause long enough to key them out before sending them to that Great Pack Rat Midden in the Sky.

They're active mainly at night and often bite sleeping humans on or near the mouth (hence the name). The bite is virtually painless but can cause severe allergic reactions, and droppings shed at the scene of the crime can contaminate the wound with the trypanosomes that cause Chagas disease, a mainly tropical infection that kills thousands of people in Latin America every year. Though the most effective vectors for the disease seem to be South America species of Triatoma, there have been a handful of recent cases in the southern U.S. The organism gets concentrated in the bugs' feces; in fact, the traditional method to test for Chagas is to let fresh, uninfected kissing bugs bite the patient, then check the bugs' droppings for the trypanosome. Chagas has even been suggested as a contributor to Charles Darwin's chronic health problems.

These nasty bloodsuckers are macabre harbingers of our late summer "monsoon." The increase in heat and humidity really seems to bring them out, so it's no surprise that in the last 36 hours we encountered the first two kissing bugs of the season inside the house. The first landed right in front of me on my drawing board at about midnight; the second casually waddled out from under our claw-foot bathtub this morning. Only the second had dined recently, though three or four itchy, swollen spots on my feet suggest that the first had already partaken of my juiciness and was looking for a refill.

CRAP! Make that three--one just came buzzing in to land on the computer hutch while I was typing. Thank goodness they're such clumsy fliers, but now I'm paranoid about how many might be sneaking around under the desk, waiting for me to put my juicy toes back on the floor. *shudder*

Because I refuse to let one live long enough to photograph it intact, here are a bunch of pix from Bug Guide: Genus Triatoma

And here's a whole bunch of skin-crawlingly fascinating information from the University of Arizona: The Kissing Bug Project

--SW

Update: By 11:30 p.m. the body count for the season was up to four--not a good sign, since we rarely find more than a dozen in the house per summer. It wasn't easy getting to sleep, listening for the dry buzz of wings and hard little thop of another six-legged vampire homing in on its prey.

Heavy weather

We've just endured a wretched three days here in beautiful southeastern Arizona. A fierce low pressure system brought savage winds, rain, sleet, hail, and snow to our little corner of paradise. The winds started when temperatures were running slightly above normal (hot, in other words) and humidities very low, which played heck with tender young leaves. Gusts up to 58 mph were recorded at the Bisbee-Douglas airport, and a substantial portion of our roof is scattered over our yard and neighboring properties. Our newly planted vegetables and many of our flowers look like they've been sandblasted.

Then on Wednesday night the temperatures took a nosedive. Thursday morning's bird walk in Miller Canyon was seriously chilly, but there was lots of activity as tired, hungry birds tried to recover from the wind and cold, and the deep canyon protected us from the winds. I felt especially bad for the Spotted Owl family 50+ feet up in a huge fir -- their nest was swaying so much that they could have used scopolamine patches. (I so wish I'd had a digiscoping camera to capture the fuzzy little face poking our from under its mama's wing.) Back at Beatty's Guest Ranch, hungry hungry hummingbirds, including two White-eareds and a Lucifer x Calypte hybrid, put on quite a show. [Subsequent observations revealed this bird to be a Lucifer-like hybrid, probably Broad-tailed x Costa's.]

The winds raged on through Thursday night, the staccato beat of rain, sleet, and hail against our bedroom window making it hard to sleep. It dried out a bit yesterday morning, but the cold, gusty conditions continued through the afternoon and into the night. As we made our way to yesterday afternoon's hummingbird banding session in Carr Canyon, the peaks of the Huachuca Mountains were thickly capped with snow, something we've never seen this late in the season in our 20 years in Arizona. Our banding crew was bundled up like Inuits except for me -- my burliest turtleneck sweater and woolly socks weren't quite warm enough, so I ended up borrowing a jacket from one of the volunteers. The weather had the birds in a much less cooperative mood than usual, but gentle application of warm breath seemed to calm them down. A male Broad-billed, two male Magnificents, two female Anna's, a female Black-chinned, and a premature escapee male Blue-throated were our rewards for soldiering through.

At least the storm brought some precipitation, which should compensate a bit for the destructiveness of the winds and cold. I'm expecting to see a renewal of nesting activity over the next week or so as birds that lost their eggs and nestlings start from scratch. A pair of Greater Roadrunners in lower Carr Canyon seemed to be getting a head start yesterday afternoon--mating just yards from the road and totally unfazed when two carloads of bird banders pulled up to gawk at them! --SW
