Flocks and Rocks Trek, June 6-14, 2020
Cottonwood Gulch has always focused on young people, but there is no reason that adults wouldn't benefit from a few days in the out-of-doors, sleeping in a tent or under the stars, and learning about the world around them in the time-honored Gulch Way. To address this opportunity, Executive Director Kris Salisbury invited John Bloch and me to inaugurate the Flocks and Rocks Trek in 2017. We did it; it was a 9-day natural history trek for adults, with a focus on geology and ornithology. At John's urging, we followed the Rio Grande Rift from Albuquerque to the San Luis Valley, then the Jemez Lineament out to El Malpais, near the Base Camp at Cottonwood Gulch. We saw every kind of igneous rock you can imagine, and many birds, including a pair of Peregrine Falcons on a cliff in Bandelier National Monument, and an American Dipper nest by a waterfall in Colorado. Our chef, Paul Meeker, observed that we had two university-level field schools going at once. John and I did share a lot, and the participants soaked it up. They were all highly-educated, inquisitive folk who just happened to be experts in fields other than flocks and rocks. A diary of our trip is here, and a spreadsheet of our birding data may be downloaded here. In that spreadsheet, go to the Table of All Sightings to see how many birds of each species were reported on each Ebird checklist. The total was 85 species. Or go to the Downloads Page for data pertinent to all my Cottonwood Gulch treks.
In 2018 the focus was more ecological, featuring the geographically unusual birds of the borderlands south of I-10 in southeastern Arizona.
That area is rampant with geology as well, and it is very different from the Rio Grande Rift. All five participants from 2017 returned, and we added 10 more.
From Organ Pipe Cactus National Monument in the west to the Chiricahua Mountains near the New Mexico border, and from the Sonoran Desert to the
high pines of Rustler Park, we saw 127 species of birds. Geology varied from a Pleistocene impact horizon to PreCambrian granite and finished with the awesome formations of Kartchner Caverns.
My plan of action for birding in 2018 is here, and a report of the outcome is
here, with the raw data
here. The success of that trip led us to spin off a more intensive birding expedition to that area, Bird Trek Arizona.
In 2020 we are going to take a truly unique trip, around the "Leopold Loop." Aldo Leopold, the influential conservationist and environmental philosopher, spent the early years of his career with the Forest Service in the Southwest. We we will visit places he knew well and wrote about movingly -- the Blue River, Escudilla Mountain, the White Mountains -- in an effort to honor his pioneering impact on environmental awareness in America. Jack Oviatt, Ph.D., former chair of the Geology Department at Kansas State University, will be our geologist, with John Bloch taking a break. Jack is wondering if Escudilla was glaciated. I am wondering if we can find Canada Jays and Pine Grosbeaks in the White Mountains.
This adventure will begin at the Albuquerque NM Airport and venture southwest into the White Mountains of Arizona, Aldo Leopold's first duty station with the U.S. Forest Service, and the inspiration for some of the most poignant images in his classic A Sand County Almanac. The White Mountains are volcanic in origin, as befits their locations along the Jemez lineament, but to get to them we must journey down the Rio Grande rift for 70 miles on Day 1. Both the rift and the lineament are familiar to some of us from our 2017 trek.
These very disparate geologic features produce plenty of habitat diversity, which gives us an immense variety of plants and animals to meet. We spend our first two nights in Water Canyon, a well-watered gash in the back side of a fault block mountain range (the Magdalenas) created when the Rio Grande rift subsided 22,000 feet in the Tertiary. We'll spend the cool morning hours of Day 2 exploring wetlands and desert at Bosque Del Apache National Wildlife Refuge, and then we'll find more cool air by driving to the top of the Magdalenas in the afternoon.
Day 3 takes us 150 miles west along US 60 (an "ocean to ocean" highway) to Arizona. We'll stop in the Plains of San Agustin at the VLA visitor center to learn about the otherworldly Very Large Array, the world's largest radio-telescope, which stretches for miles around us. Then we drive past the aptly named Sawtooth Mountains as well as through aptly named Pie Town (dessert anyone?) to the center of Leopold's Arizona world, Escudilla Mountain. We'll note the remains of the fire-ravaged spruce-fir forest on the mountain slopes and camp in the luxurious grassland on the "loop" road 56, about 1000 ft below and three miles south of the summit of Escudilla Mountain. The springs there will fuel a chorus of frogs, and perhaps rails, as we get used to the brightest starscape we have ever seen. We'll read about the grizzly who once roamed this mountain and how it inspired Leopold's classic essay "Thinking Like a Mountain," a paean to his Land Ethic. The next day those unbothered by the thin air at 9,000 feet can ascend the three miles to the fire look-out and share the panoramic views. Excellent views can be had only one mile up this trail.
Day 5 will take us to nearby Springerville for provisions and up into the White Mountains for a look at the vast subalpine grasslands that inspired Leopold's essay "On Top." Perhaps we'll find Frijole Cienega or "the boneyard." Then we'll return to "civilization" at Alpine and drive a few miles south to Hannagan Meadow, another spruce-fir site. From the campground one can look west onto the fire-ravaged slopes of the Black River drainage. Not far to the east is the Blue River drainage, into which we descend on Day 6.
The contrast is dramatic. Hannagan could be in Colorado. Down below, Blue River Crossing is a northern extension of the canyon ecosystem of southeastern Arizona. The whole area is an Arizona Important Bird Area. We'll look for Common Black Hawks there, and drive down the canyon as far as we can get, looking for coatis and imagining the wolf restoration that would have made Leopold glad, but was vigorously resisted by local ranchers. On Day 8 we head homeward, stopping by Luna Lake to see the nesting waterfowl and provisioning again in Springerville. Then it's north to the Zuni Mountains, where we will encounter the massive sedimentary landscapes of the Colorado Plateau. Nightfall will find us at Cottonwood Gulch, with its hot showers and cabins with bunks. We'll leave as early the next morning as we need to for the two-hour drive to the airport, noting the intersection of geological provinces as we head toward the city where Leopold proposed the Gila Wilderness 99 years ago.

The summit of Escudilla Mountain, as seen from the Terry Loop, where we will camp, within earshot of Profanity Tank, at the interface of the luxuriant subalpine grasslands and the spruce-fir forest.
One of our stops will be at Hannagan Meadows Campground, where perhaps we will be visited by "camp robbers" aka Canada Jays, members of an isolated population on an evolutionary island.
When we visit the Blue River IBA in June, the vegetation will be lush and the birds abundant and conspicuous.
The Latest in Commissary Trucks
For this first year (2020), we will begin with a turbo-charged BTA 1.0, which will take you to see and hear Elegant Trogons, Flammulated Owls
(an old specialty of mine), Mexican Chickadees, half a dozen species of hummingbirds,
Greater Pewees, Tropical Kingbirds, Gray Hawks, and a slew of other species that one must come to the Deep Southwest to find. We will also try to find
a few of the specialties that are the bailiwick of BTA 2.0. Along the way I will present chalk-talks
on the ecology of the region and the
nitty-gritty of range expansion. If you ask, I will
explain why bird names change so often, how the revolution in molecular biology has revolutionized our understanding of the genealogy of birds,
why female Black-chinned and Ruby-throated Hummingbirds are identical but the males aren't, and a few dozen other stories from my years of teaching
college-level ornithology. Bird Trek Arizona 1.0 starts
at the Tucson Airport on Saturday, May 16, 2020, and ends there on Sunday, May 24, 2020. You can sign up now by following the link above. You can also
get a lot more information about the trek on that page. If you have a question for me, send your email to birdtrek at archmccallum.com.
This trek explores the mountain islands and desert seas of southeastern Arizona at a time of maximal bird activity, just before the summer heat sets in. Migration will still be on, but breeding birds will be on territory, making plenty of noise. After meeting at the Tucson airport we will set up camp in the saguaros of Tucson Mountain Park, where we will meet the common birds of the Sonoran Desert while enjoying afternoon libations and hors d'oeuvres. The next morning we will comb the desert for Rufous-winged Sparrows and Elf Owl nests while checking off the rest of the desert specialties. We'll also hop into the vehicles, if necessary, for a quick trip to a known Harris's Hawk territory. We will lunch at the Arizona-Sonora Desert Museum, whose outstanding exhibits will explain desert ecology to us. They also have a number of live animal exhibits, including a hummingbird enclosure in which Costa's Hummingbirds will be nesting. Then we'll head to a new campsite in the high pines of Mt. Lemmon, where we'll be surrounded by Mountain Chickadees, a Rocky Mountain Species, and Yellow-eyed Junco, a Sierra Madre species, among many others. After dark, perhaps Flammulated Owls will hoot ventriloquially from overhead. If so, we'll be glad we are camping out.
On day 3 (May 6). after catching the dawn chorus of Buff-breasted Flycatchers and spending a leisurely morning looking for Common Black Hawks (our only chance) we will descend through the life zones to the Saguaro forest east of Tucson, then southward through the desert grassland south of I-10 and its Botteri's Sparrows. We'll stop for a listen, and then drive on to Patagonia, for quick stops at the Paton Hummingbird Center and the Roadside Rest, time permitting. Soon we'll be settling into the lap of luxury at Patagonia Lake State Park, with a lake and hot showers at our disposal. We'll see if the Rufous-winged Sparrow is still defending the bath-house, and comb the far lakeshore for White-faced Ibis, Neotropic Cormorant, and Mexican Duck, along with better known waterbirds. We will also hope for a return of the pair of rare Black-capped Gnatcatchers that nested successfully in 2019.
Day 4 will be our banner day for Group 1, ultra-rare invading species, with Violet-crowned Hummingbird, Thick-billed Kingbird, and Tropical Kingbird likely, and Rose-throated Becard and Black-capped Gnatcatcher requiring only a little luck, as single pairs of these two species are known to be in the area. Naturally, such an exciting day will require an early start. We'll go first to de Anza Trail in Tumacacori for the kingbirds and becard, then back to camp for lunch, then to Patagonia for the hummer and perhaps an early Varied Bunting. If there's any time left after we return to camp we may visit the lakeshore again, but most will probably want to sit around the circle and compare notes with a nice beverage in hand.
Day 5 will begin with a concerted effort to find the local Black-capped Gnatcatchers, who live in the desert scrub maybe a quarter mile from our campsites (which are at the edge of the campground where the birding trail begins). Then we'll break camp as quickly as possible to get to the Roadside Rest before midday heat sets in. After a leisurely morning there and in Patagonia, we'll head over to Sierra Vista for groceries and then spend the remainder of the afternoon at Ash Canyon, hoping for Lucifer Hummingbird, but sure to see many Group 2 species for the first time. Then we'll ascend to the cool pines and Buff-breasted Flycatchers at Reef Townsite, hoping a Tufted Flycatcher will be in residence. Owls and nightjars frequent this campground, and the view of the lights 3,000 feet below is spectacular. A quick turn-around the following morning (we may skip Reef, depending upon the flycatcher situation) will take us back down to the base of the Huachucas and a half-mile hike to the Rufous-capped Warbler nesting site. Then we drive and drive and drive, through Bisbee and Douglas to Portal, AZ, gateway to the "Yosemite of the Southwest," Cave Creek Canyon.
We'll spend two leisurely nights in the canyon, with forays into the desert for thrashers and sparrows, up the canyon for trogons and hummingbirds, and behind Silver Peak for titmice and more sparrows. On the penultimate morning of our trip, we'll climb to 8,000 feet at Rustler Park, where we'll focus on Mexican Chickadees, but see many other Madrean Forest birds as well. After lunch we'll descend the west side of the Chiricahuas and head for another luxurious state park, Kartchner Caverns. The birding is good there, too, if we have time. For sure we will clean up and have a final feast and get a good night's sleep (like all the others) before heading west for the airport early Sunday morning.
We will visit four major habitat-types: (1) Desert, home of the Elf Owl and Gilded Flicker.
We will visit four major habitat-types: (2) Montane Conifer Forest, home of the Mexican Chickadee and Red-faced Warbler.
We will visit four major habitat-types: (3) Canyon Woodland, home of the Elegant Trogon and Arizona Woodpecker.
We will visit four major habitat-types: 4) Riparian Gallery Forest, home of the Rose-throated Becard and Gray Hawk.

My innate interest in birds received early encouragement from my parents and my uncle, who were all accomplished naturalists. Growing up in Dillon, South Carolina, I spent weekends in the woods at the family farm and looked forward eagerly to occasional Sunday afternoon trips to "the beach," two weeks every summer in the North Carolina mountains, and Carolina Bird Club meetings, where I received abundant encouragement from adult birders and ornithologists, especially the Chamberlain brothers of Charleston, S.C. After college, a stint in the navy, and a few misadventures, I found myself working as the resident naturalist at the base camp of the Cottonwood Gulch Foundation, in the Zuni Mountains of New Mexico. My bird studies there, over a 14-year period, led to a Ph.D. at the University of New Mexico, Birds of North America accounts of the Flammulated Owl and the Mountain Chickadee, and other publications.
My interest in southeastern Arizona was crystallized by winter residency in the Chiricahuas, 1977-78, and 1978-79, where I was among many who saw the first Eared Trogon (now Eared Quetzal) documented in the U.S. I returned to the Chiricahuas for a sabbatical in 1999-2000.
