Bats and Nighthawks are taking their final sips as their shift ends, the woods around is dark and the creatures themselves invisible, but the pond surface catches enough dawn to show their reflections and so I can only see them upside down. Nothing is as it seems in the crepuscule.

I go about the usual circles, opening the irrigation, back to the pump to turn it on, out to the pastures to see that all is operating well and efficiently using that priceless water, adjust sprinklers, unscrew nozzles to clear out grit and pebbles the pump has sucked up and that will clog an opening (and so I get the usual soaking which still feels cold with the dawn standing at 50 degrees), then swing on back to The Stockpond to see who has come now the sun is heading towards the cliff bottoms. Just the usual neighbors hangin’ out at the cafe: warblers, sparrows, tanagers. Ernest Tubb undoubtedly in a cowboy hat twangs out from the dashboard and from 1950, “I Love You Because”. I sip coffee, munch a tortilla, munch on the day’s cow chores, munch on all the fences that are also twanging out and popping off their posts. I think back to when a ranch visitor almost twenty years ago asked me one dawn in the cooktent if I thought it was going to rain, and I answered him, “Yessir, eventually.”

No Western Tanagers, they seem to have left en masse.

The dark shade of large and dense mesquites invites me to take lunch up on the rim of an old stocktank that still collects the runoff from the hills across the road if a storm cell dumps water in just the right canyon above. I can look down from that bank top at the wheel lines and can see their watering stop when the pump shuts itself off before the 1 pm peak hour rates begin. The scenes below on the fields and above on the hills and mountains and the cool shade invite a siesta though I must beware the large ants foraging around me. At least I must not roll over on any. An orange from some place far from this foodshed is my desert, the peels are left for a favorite steer who has learned to eat them. A thought comes: we humans are no less (and no less legitimate) recyclers of biomass than are those mahogany-colored ants (or gophers for that matter), the difference being only of scale. We do it on a continental, even planetary, scale. I’ve been at the bottom of those orange skins becoming the humus of a spot very far from where they were brought into being by the natural processes and cycles in their homeland, or bioregion if you will, and I’ve been responsible for their being added to the biomass (and decomposing litter) in this one. Humus is neither created nor destroyed, but transferred from one place to another? Multiply that by the rest of what I eat in a day, and that again by 7 billion of us, and we will know that indeed we are changing more than just the Earth’s climate. Will the result be any less “natural” an outcome than what should have happened here without us?

The mesquites are gravid with pods, though many trees are still in bloom and I take in delicious, deep drafts of the sweetness, allergies be damned. The calves are eating the flower spikes as if they were popsicles, their mammas reaching higher for the even headier and protein-rich catkins of Catclaw Acacia, with blossoms that fill the air with an indescribably rich fragrance one might only come on in perfume shops hidden down tangled alleys of old Mombasa.

Seven almost-grown Mule Deer join me on the pasture as I head out across to turn down the risers to conserve untold thousands of gallons of water that would keep flowing out if I didn’t. It is always a big hassle to do this, but I don’t dare waver from the chore. The deer are unsure of me yet also quite unafraid and they let me approach closely as I tend to my own business at hand. They come to graze on the yellow sweet-clover which in its tall drifts is loudly abuzz with honeybees, and there is the maturing barley, oats, wheat and rye, the globemallow, bermudagrass and saltweed for them and the javelina, Coues’ Deer, jackrabbits and cottontails–and the cattle.

These Mule Deer have the same power to enchant as the Catclaw blooming at the pastures’ edges, are so startling in their near-tameness as to seem visitors from one of the Yaqui ania “dream worlds” (if dream they be) where all is flowery and the streams do run. The Yaquis would understand how all in the crepuscule here is not as it appears, living as they do at the other book-end of this Sonoran Desert where their own rio comes to the sea, or at least used to. As I learned from spending a winter in the extreme south of Sonora, everyday life at the opposite shore of this desert is in many ways like ours, at least here in this wild valley of unpaved roads and people who know that as with the word “cowboy”, “neighbor” is both noun and verb.

The physical surroundings of that far land in Sonora take little adjusting to if once you have become at-home on the San Pedro, and I look up from the Mule Deer to hills and peaks that remind me of that beloved part of Mexico. The colors at this season, above the lush riverbottom flats I and the deer stand on, are the same grays and pale browns of the monte mojino–the “tropical deciduous forest”–of Alamos, only here the trees and shrubs are shorter, with no closed canopy because we are much colder though that is hard to remember just now with the afternoon temperatures always in the 90s and very soon in the 100s. Our grays and browns are even more pronounced than usual, because the last rains of any note fell eight months ago on this range. We end up with no closed canopy here on our hills not only because of the cold, but because of the dryness: it looks like every last Foothills Paloverde up there has gone from green to brown and died outright from the drought. The O’odham believe that saguaros we see had once been individual people, and so I can imagine the few of these cactus trees that we look up at on those heat-shattered hills among the dead paloverdes are longing for the arrival of the temporales. The saguaros struggled to bloom this year, and none of them flowered right around here. Will it rain this summer? Will it ever rain again? Yessir, eventually.

Full Moon is lowering itself towards the crest of the Rincon when I leave in the “dark” and thread the ridge above Pool Wash and slowly lower myself towards the canyon bottom and out on the Cascabel Road. The grand, bare cliffs are all in a glowing mist, a world that in this moonlight is there and is not there. Nighthawks are purring loudly and then softly, and from every knoll and canyon bottom rings out Whit-will-do! Whit-will-do! of Brown-crested Flycatchers … the early bird catches the cicada. On the road drive to the pastures the air is sweet and cool on my face. Owl is going home, Poorwills fly up from the gravel or flicker into my headlights, kangaroo rats bounce and jackrabbits try my patience when they decide that safety lies under turning truck wheels and not in the creosote flats they could peel off to instead.

My chest aches in the cold air, but then again it has done since I got knocked face-down flat to the ground yesterday afternoon by the electric fence when after crawling under and to the other side of it, I lost balance while I was getting to my feet and leaned back enough to lay the wire across the nape of my neck … bang! I long to direct the herd grazing these bottomland pastures from horseback alone, abandon the wires and the batteries and the electricity. The temperature and Moon are dropping, and I get the impossible pleasure of seeing four moonsets in succession, over this ridge or that, or when Moon snuggles himself into one gap in the mountains or other while I myself swing around north and south to drop cowboy gates and open hydrants out on the pastures …

[…]

Bright his smile may be, but his night at The Stockpond is far from a silent one. The dark of the mesquite bosque is all sound and singing–Cardinal, Yellow Warbler, Bewick’s Wren, Lucy’s Warbler, chats (lots of chats), tanagers, grosbeaks, Mourning Doves, Bell’s Vireos, kingbirds, House Finches, and a Vermillion Flycatcher that’s dancing mid-air. While singing out, he slowly crosses high over the pond, demanding of the avian world, “Oh, am I a stud, or what? Dig me!!” The fiery red little bird likely had done that through the whole night, dancing in Moon’s follow spot. The pair of Mexican Mallard swim around each other, painting yin-yang symbols with silvery water.

Later in the bright morning sky three Purple Martins, two males and a female, are sewing patterns on the blue, letting out far-carrying notes, twings and plangs in a courtship danse apache among two rivals and their would-be mate. Below in the mesquite edges and the weeds growing ever taller fledgling Lesser Goldfinches are complaining to their parents that not enough bacon has been brought home lately, “you don’t expect us to go out and get it ourselves … do you?” My life as ranch hand with its shocks by electric fences and lightning seems as tenuous as that of the baby bird whom I’d just saved from a pool of irrigation water in which it had wet its feathers thoroughly. I can decide to rescue it if I can as validly decide to leave it to drown, though all I probably did was save it as a fresh meal for a coyote. So be it. I put it way off into the grass, where it will stay hidden at least for a while, could dry out after all and end up changing the entire course of Evolution.

Dawn brings with it temperatures in the upper 40s still. Chunks of cobalt, chunks of lapis take wing–many Blue Grosbeaks, and Lazuli Buntings. In the gray light, a Lucy’s Warbler is jumping in and out of the cavity in the railroad tie gate post in which one of those birds was busily putting in a nest a bit less than a month ago; I thought it had been abandoned. There are many chirping babies around and if I remember, Lucy’s fledge with a startling quickness.

While I sit in the pickup sipping coffee after completing irrigation rounds, a Gray Fox comes along to get a drink at the pond. A beautiful animal, it is–red fur on its legs, and a swath of red that runs diagonally from its red ears down the sides of its body. It sits over there for a good long while, black-tipped tail draped elegantly, but acts nervously about something beyond it most of the time though it didn’t seem to care about me. Around him many swallows are flying in for quick on-the-wing dips of their bills into the water, and there’s a real “mess” of tanagers, of both species, coming to drink as well. One of them is a first year male Summer Tanager in that peculiar transition to adult plumage: green, blotched with red all over like either I’m seeing spots before my eyes or he has some dreadful tanager pox.

Sapphire blue damselflies are alighting on the irrigation hoses wherever the units have put out enough water to build little ponds that will of course drain away. The air has heated to just short of 100 degrees, and the grassland birds have discovered quite the way to stay comfortable: with the humidity at 4%, the seventy-foot wide zone of wet soil dwn the center of which the wheel lines sit becomes a giant evaporative cooler, and the upper spokes of the wheels of the units are crowded with birds who get as high as they can up under the wide, flat aluminum “tire” so it can shade them. Close up under one wheel canopy alone there were stuffed a Lark Sparrow, a Cassin’s Kingbird, and two Western Kingbirds, obviously enjoying that shade and “cool”!

The plaintive cries of a Poorwill came up from the banks of Pool Wash in the earliest dawn, as I was packing the truck to get down to the pastures. They’ve hardly been heard since those evenings more than two months ago when the birds seemed everywhere from Mason’s to here, on the road, in the air, or calling.

After I’d got the water going, I drove to the west end of the fenceline between #1 and #2 pastures, which affords a good view of sprinkler head problems in the line across to the south. I was distracted from work, though, by a bobcat running from the middle of that pasture to the protection of the bosque along The River. Actually it was trying to escape from a raven that was harassing it likely just in devilish fun, as ravens seem wont to have. Then just as the bobcat disappeared into the mesquital: another cat, much larger than a house cat but not as big as the bobcat, and of black color, came scampering along in the same direction and also from the middle of the field but in a line further away from me. It was gone too quickly to get the binoculars laid on it and focussed. I’m thinking this was yet one more (of the many talked about when people here are feeling safe) sightings of our ever-elusive-but-never-to-be-documented Jaguarundi.

If such an animal were to be proven resident in this valley, the entire history and game of keeping “The River” the marvel that it remains would be changed in an instant. Myself I have full confidence that I have seen the critter here and more than once, sometimes close enough to study it well and at leisure, sometimes just a flash of body and incredibly long tail crossing Cascabel Road or a ranch road at dusk or dawn especially when the road was in such bad shape that I couldn’t go faster than five mph in the old Ford 100 pickup. The Jaguarundi hereabouts fills the same place in after-dinner conversations, when people are feeling expansive and out of earshot of hostile sceptics, as that held by the Onza in campfire talk in the remote monte of Sonora, or by the dreaded Escorpion that “is” an iguana-like reptile with poison-dripping fangs high in the rainforest trees in Costa Rica, or by the Chupacabras that stalks the corrals out on the Mexican deserts. Erudite biologists and people like Nathan Sayre whose research is always impeccable state that Jaguarundi being seen here is an impossibility, end of conversation! … yet we are tantalized by write-ups like that of the naturalist Stan Tekiela, in his book, “Mammals of Arizona Field Guide”:

Rare […] Very secretive, with a range from South and Central America into southern Arizona […] occasionally one jaguarundi is seen […] It is possible that some of these are the offspring of feral house cats. There are also reports of captive jaguarundi escaping and living in the wild.

I drive off soon as I can manage and find a phone, and call our naturalist Ralph W. who has been setting out cameras for years trying to nail down for us once this Holy Grail of our conservation. Later in the morning he and Kathleen and I hunt for tracks and try to determine if there’s enough evidence to warrant doing another camera project, but we don’t find much in the way of exciting clues. We do come on Badger sign, and an interwoven set of curving lines in the flour-like dust that tell where two rattlesnakes became more than strangers in the Sonoran Desert night–as I followed their movement through the powder and imagined the grace of what went on, in my mind’s ear there played the Ravel “Bolero”.

A Spotted Sandpiper is visiting the mud shore of The Stockpond again.

The Stockpond is perfectly still, and perfectly reflected in its dawn-pink mirror is the pair of Mexican Mallard … in the bright green mesquites all around the chats are doing what they do best, chatting. The air has a comfortable coolness to it but by afternoon will reach nearly to 100 degrees.

At lunchtime a Pine Siskin alights in the branches of one of The Stockpond mesquites, just above Tom O., Nancy F., and me, while we eat lunch on the bank.

A first cicada for this place (they were active on range a week ago already) splits that afternoon heat with a long wailing rattle, this sound the faultline where spring ends and a summer begins that seems never will end. Blossoms on the spikes of Copper Globemallow (Sphaeralcea angustifolia) are beginning to open, now the plants finally have recovered from those two deep freezes that had killed most of them to the ground, if not altogether. (In other, milder years there can usually be found a flower or two on the plants in every month of winter.) This much-favored browse of our herd and the deer who also live with us is nutritious for four-leggeds. It and other members of the genus Sphaeralcea are important to livestock from here down through the Mayo lands of Sonora and far into Mexico and they respond in a positive way to the animals’ pruning.

Small Azure butterflies, showing copper on wings above, and below a sheen of silver-lavender laid over black zebra striping, are coming to the yellow Sweet-clover flowers.

Western Tanagers are becoming much more noticeable, and in patterns of black, white, yellow and orange-red they flash down The Lane in front of the truck.

The temperatures begin today to cross into the 90s, pushing the vegetation along into Summer that a calendar claims falsely will not come to us for more than another month. The Stockpond’s surface is covered with a film of pollen. Even the cattle are coughing.

On the pastures yellow sweet-clover (Melilotus) is growing lushly, tall, and blooming abundantly, its fragrance carried on the wind and inviting in the Mule Deer whose favorite graze it seems to be. Our cattle go right after this naturalized plant as soon as they’re rotated into a new pasture with it, too, even though it has coumarin within it that supposedly can affect an overindulging animal badly. I’ve never seen any such outcome with the plant, though, I guess because the toxin cannot become active without enough humidity for a mold to grow on the plants. (Humidity will at least half the time register in the single digits this month and next; so much for mold …) Cowbirds have come along in numbers, and true to their name are attending the cows. A last flock of Chipping Sparrows came down to one of the large puddles around an irrigation riser: the birds will be gone any day to the North, or leave for the oak woodlands at higher elevations here where they spend the summer in spare numbers. In Pasture #3 a pair of Brown-crested Flycatcher are purrrrtling and courting, at least I think they’re Brown-crested going on the strength of that rolling purtle, but I wasn’t able to see those tiny details of how far towards the tip goes a darker banding on the tail feathers. The other calls don’t match exactly those described for either Ash-throated or Brown-crested, though are closer to “whit-will-do” than to “ka-brick”. The field guide isn’t very helpful, either, with,

Ash-throated Flycatcher:
smaller bill than Brown-crested;
very pale gray [breast];
very pale yellow [belly]

and,

Brown-crested Flycatcher:
larger bill than Ash-throated;
pale gray [breast];
pale yellow [belly]

Truly a “dastardly duo”, as Tucson Audubon Society calls such confusing pairs of species. If I accidentally left the big hose out of the port on the wheel line irrigator, those birds would immediately take up housekeeping (or at least house building) inside the pipe-axle’s ready made cavity. Sometimes I find the cows have unhooked that firehose from the port and left it flung out on the grass to the side, which also leaves the inside of the axle/pipe open to the househunting flycatcher pair. Years ago I hooked up a water hose to an open port of one of the units elsewhere across The River, turned on the pump, and in a few seconds had distributed a nest in pieces into a couple dozen sprinkler heads and there was the devil to pay to get them all cleaned out again. You only have to do that once before you flush out a system like that first with the endcaps off, should you have found one of those ends open or that a hose had been off for a few days! As much as these flycatchers are among my favorite birds, I want their attention be focused elsewhere for nest sites such as “natural” holes abandoned by the woodpeckers who had excavated them in the saguaros on the slopes just above us.
