Winter's Subtleties

Imagine: you're immersed in the early-winter splendor of the Chiricahua Mountains.

The air is brisk and glorious, and, hiking up South Fork, you settle into the depths and subtleties of the season...

into the drifts of sycamore leaves...

Light gleams from the seedheads of Cane Beardstem...

and native thistles...

and Deer Grass.

Streamside willows still hold a few leaves,

and the sycamore's bark takes on a subtle hue of green from chloroplasts.

The riot of nesting and migrating birds has passed, and now you find winter's companions:

Acorn Woodpeckers are busy among the pines and oaks,

Gambel's Quail enliven the mountains' feet,

and Spotted Towhees scratch in the underbrush.

In fact, Spotted Towhees are having a banner winter in the Chiricahuas. Regrowth from the big fire of 2011 must have reached a stage that offers towhees plenty of nesting cover, for we've never before seen them this numerous in winter.

Adult male Scott's Oriole

And... what is a Scott's Oriole doing, still coming daily to our hummingbird feeders?? He lasted through the November snowstorm and shows every sign of being a snowbird in reverse. There's nothing subtle about this bird's summer yellows!

Okay, who has guessed? New camera!

Portal, Late Summer

We've had a full week! Many friends who know the Sky Islands choose the late monsoon season to visit, when hummingbirds are streaming south, nectar-feeding bats cluster around the feeders, and masses of clouds keep the temperatures just about perfect. (Of course the gnats find the temperature perfect too!)

South Fork, singed trees and all, has been the site of much trogon activity this week! (Photos by Narca)

Diminutive Buff-breasted Flycatcher along the Herb Martyr Road

Jon Dunn, our good friend of several decades (!––How can it have been so long?), is in town with his WINGS group, and yesterday I joined them for a fine day in the field. We wandered down Herb Martyr Road, where flash floods the day before had brought new debris across the road, and had also cut a new trench at the Crystal Cave wash, though it was manageable in the big van with its high clearance. After Herb Martyr and a stop at Southwest Research Station for the hummingbird show, we continued to the barricades at East Turkey Creek––the current site for anyone undertaking The Great Mexican Chickadee Quest. The higher Chiricahuas are still closed due to danger from the big Horseshoe Two burn and associated flash flooding.

The day brought many highlights:

We did find a Mexican Chickadee, albeit only one, and not terribly cooperative. Today Jon and friends will make a second try for better looks at The Chickadee. The Chiricahuas are the only accessible locale in the States to find this prize. They also live in a mountain range in the bootheel of New Mexico, but that is on private land and access is difficult, even on the very rare occasions when permission can be obtained.

One of the fledgling Northern Goshawks was broadcasting his wish for a meal. Jon spotted the bird in a pine not far away, and several enjoyed scope views of the youngster before he moved higher up the ridge.

Returning, one of our folks spotted a male Montezuma Quail, standing stockstill on a rock, not 20 feet from the road. From inside the van, we scrutinized the place until several more of these cryptic birds revealed themselves. It was a family group––a gorgeous pair of adults with about six half-grown chicks in tow.

Acorn Woodpecker at Jackie's feeders in Paradise

After a stop at Jackie and Winston's feeders in Paradise (Juniper Titmouse––yes!), we headed back to Portal. Along the way, a richly-colored Blacktail Rattlesnake decided that the big white van was definitely suspect, and a shower of sound cascaded from its rattles as we photographed the beauty.

Black-tailed Rattlesnake decides that the van isn't trustworthy.

The evening finale brought great views of a little Western Screech Owl and the swooping mass of nectar-feeding bats that visit our hummingbird feeders each night at this time of year. The nearly full moon illumined drifts of cloud in the deep night sky.

Silverleaf

The first hint of something extraordinary is all the activity along the South Fork road, just below the bridge. A dozen Black-headed Grosbeaks forage on the ground and munch breakfast in the branches overhanging the road. Apache Fox Squirrels nestle in the sprays of leaves. Acorn Woodpeckers are very busy, doing what they do best. A big Silverleaf Oak––one of the biggest I've ever seen––has produced a bumper crop of tiny acorns, and word of the feast has spread.

Normally Silverleaves are shrubs or small trees, associated with Madrean Evergreen Woodland. This giant stands about 40 feet high, with its roots well-watered by the nearby spring. (Google tells me that the national champion is 85 feet high, so our South Fork champ is just a teenager!) Like other oaks of arid climes, the leaves are leathery to resist water loss. The name comes from the leaf's silvery, reflective underside.

In a good year, many animals thrive on the acorn crop, and last winter's El Niño rains have brought on a true bounty of acorns. I tasted one and it wasn't bitter––the amount of tannin in acorns varies with both species and individuals. Native Americans harvested acorns, prizing the best-tasting (such as Emory Oak), and giving special treatments to those that were bitter from tannin. This particular tree's acorns must be especially good-tasting, to attract so much attention from diners, while the surrounding oaks are ignored, at least for the time being.

Acorns alone don't account for the feeding frenzy happening today near the South Fork bridge. There also must be plenty of insects in the vicinity of the spring. Flurries of flycatchers––Brown-crested and Dusky-capped, Sulphur-bellied, Western Wood-Pewees––add to the tumult, while a male Blue-throated Hummingbird squeaks from the top of the Silverleaf and a Painted Redstart tumbles from tree to tree. An Elegant Trogon still maintains his territory near the bridge. Plumbeous Vireos, Bridled Titmice, and Brown Creepers search for food for growing nestlings.

Ahh, South Fork. How good it is to walk here again!
