Noticing

Another El Niño storm has blessed early February. I'm out of the house, to recall from Oregon days the delights of walking in the rain. Most of the storm has passed, and only a light mist still falls. Cave Creek is roaring. Clouds alternately hide and reveal the highest cliffs.

The wet bark of trees has a different look––how intensely green is the Arizona Sycamore bark! The deepest green looks like a new layer of moss or algae from the recent wet spell, but the more general greenish tinge suggests something else––chloroplasts in the bark. I've looked at those green chloroplasts before, when the trees were dry and the colors paler, without really noticing.

This tree may be like the Gumbo-Limbo of tropical dry forests, which exposes its green bark when it is leafless, and is able to photosynthesize––to make food––to some degree throughout the leafless months. It's never completely dormant that way, and gains the advantage of nourishing itself through the lean times. Both of the tree species have peeling bark, too, which sloughs off any epiphytes like lichens that try to gain a toehold on the trunk and branches. That peeling also exposes the underlying chloroplasts. (The photo below hasn't been altered in any way––it is really that green!)

Are sycamores greener in winter? Have you noticed?

The Air Says "Spring"

The calendar may say Winter, but today the air announces Spring. A fresh, rain-washed breeze riots through a grove of companionable Arizona Cypress that leans over South Fork; their droopy branches stir.

The creek flows strongly, at long last, after the past year's severe drought. Our big water debt has been helped by the storms of El Niño. Portal just recorded its wettest January in 39 years of record-keeping, something to celebrate. At Kim and Lorraine's house, the total topped 5"; Alan and I recorded 4.5". The creek has obviously flooded recently––big clumps of Deer Grass along its margins still lie flattened. New greens touch the grasses.

The leps agree that spring is around the bend. I spy several small moths flitting around the trunks of the oaks, but no butterflies yet. Soon!

The willows at the bridge are budding. Their blooms will lure in Arizona and Siva Hairstreaks, and migrating Yellow and Wilson's Warblers will forage in the leafy thickets––soon!

The Canyon Wren is bobbing more energetically today, and scolds me. I whistle, but can't yet trigger his cascade of song––soon! Very soon!

Skagit River Flats

After days of visiting family and painting a playroom to look like a ferny forest inhabited by dinosaurs, I step onto the night ferry from Port Townsend to Whidbey Island, Washington. The lights of town recede, and the dark waters and crisp night air of Puget Sound envelop the ferry.

My friend Jim Shiflett is waiting at the dock for the ferry's arrival.

Next day finds us in the flats of the Skagit River Valley and on Fir Island, which lies between the north and south forks of the river, bordering the estuary. Clouds hide, then reveal the sun. There's hardly a breath of wind. Western Washington is enjoying its warmest January on record.

We're in prime raptor habitat, although today the hawks and falcons are little in evidence. A rare dark-morph Rough-legged Hawk regards us. I'm struck again by how small its bill is, when compared to a Red-tailed Hawk's. A couple of Merlins dash past. Bald Eagles abound, numbering perhaps 40 or 50. Pairs perch near their huge stick nests, ready for the next nesting effort.

We find a big concentration of Snow Geese. Those that winter here in the Skagit Valley return each spring to breed on Wrangel Island, in the Arctic Ocean north of Russia. (Wrangel also has the world's highest density of Polar Bear dens, and Woolly Mammoths survived the longest on Wrangel, until about 1700 years ago!)

The Snow Geese share the Skagit Valley with literally thousands of wintering Trumpeter Swans. Many of the local farmers are paid to raise forage for the swans. However, we see two fields where swans and geese are discouraged in a novel way: the farmer has put out a Bald Eagle decoy in the center of each field, and the ruse appears effective. Neither of the fields holds a single other bird!

In the tidelands, masses of driftwood pile up, interspersed with swathes of grass. Short-eared Owls roost in these twisted roots and logs, emerging in late afternoon to hunt. One perches atop a small conifer growing amid the wrack––how beautiful these owls are!

Winter Walk in South Fork

The beauty of the South Fork of Cave Creek Canyon never fails to enchant those who stray into it. Most know it in spring when neotropical migrants pour through the canyon corridors, or in summer, when the croaks of Elegant Trogons echo off the burnt orange cliffs, overlain with lime-green lichens.

Now it's winter, and peacefulness lies as deep as the drifts of sycamore leaves.

I often hike up the South Fork road with friends, usually Peg or Rose Ann, but some days when the call of the canyon is especially strong, I go alone, quietly. That's when a Black Bear is more likely to amble across the dirt road, oblivious to a hiker. That's when I'm more likely to tune into the small flocks of confiding Yellow-eyed Juncos that forage unobtrusively at the road's edge.

Today sparkles, after last night's mix of rain and light snow. The luminous cliffs glow intensely orange against the skyblue. Flocks of ubiquitous Mexican Jays probe into crevices and under leaves. An Arizona Woodpecker taps softly in the oaks.

Today a troop of Coatis cavorts in the creek bed and noses through the drifts of fallen, rusty-gold leaves. Females and young gather in troops like this one. The males (like this big guy who visited our house last month) are solitary. In Costa Rica, people used to think that there were two species of Coatimundi––those that lived in groups, and those who were solitary, the "Lonely Coati."

When our own quiet matches the forest's quiet, we find its life.

Bosque's Other Birds

While cranes and drifts of white geese attract much of the attention at Bosque del Apache National Wildlife Refuge, other exquisite waterbirds also slip quietly through the ponds. Northern Pintail and Shovelers paddle about; Buffleheads dive.

We have stopped to study a dark raptor when just the head of a Trumpeter Swan comes gliding past our car. The huge bird is swimming in the canal that runs alongside the road, and is too tall to hide its presence.

The Trumpeter Swan Society is tracking all sightings of Trumpeters this winter. If you should see one, please report it to Peg Abbott (peg@naturalistjourneys.com). She is heading the effort.

The days are cold (thankfully without wind!), and Greater Roadrunners sun along the route, exposing their dark back and rump feathers to soak up the sun's warmth.

Winter Interlude: Bosque del Apache


Snow Geese at Sunset (Photo by Narca)

The Rio Grande River hosts many thousands of wintering Sandhill Cranes, Snow Geese, Ross's Geese, and other waterfowl. Nowhere can these spectacular flocks be enjoyed and photographed more beautifully than at Bosque del Apache National Wildlife Refuge.

The experience isn't simply one of enjoying impressive flocks of impressive birds. Somehow, when these birds are placed in the Bosque habitat, rich with the rusts and golds of winter, and beneath the expansive New Mexico sky, the whole encounter wakes me up, deeply. The clear light, the cold air, the rattle of cranes––all of it is profoundly rousing.

This time I've journeyed to the Bosque with Noel Snyder, Tony Donaldson and Rod Drewien. Rod is actually working, counting the geese, while the rest of us play. His counts this year of the white geese reveal a mix of roughly 75% Snow and 25% Ross's Geese. Rod has censused geese and cranes for decades, and brings exceptional expertise to the task.

At the Bosque, ponds along the lightly-used highway north of the refuge are a traditional lounging site for geese and cranes. Photographers also stage here at dawn and dusk, hoping to capture that perfect moment when light bathes the waves of incoming cranes and geese. We endure the early morning cold, to watch as sunlight begins to limn the cranes and to ignite the white geese.

The cranes stir, preen, dance. We know when they begin to contemplate flight, because the arousing birds stalk towards the edge of the gathering, craning their necks. Soon wave after wave of cranes is airborne, off to find the day's forage. In evening they return to their safe harbor for the night, as do we.

Pure Magic


Frosty morning at Bernardo (Photo by Narca)

Bernardo Wildlife Management Area, north of Bosque del Apache in New Mexico, is attracting huge numbers of Sandhill Cranes, Snow Geese and Ross's Geese this winter. Their corn crop is ample, and many thousands of cranes and geese are feasting on the bounty.

Noel Snyder, Tony Donaldson and I arrive early on this very cold morning. Frost envelops the sparkling plants. A trio of Mountain Bluebirds watches our progress along the canal. Temperatures plunged to 12º F last night, and many of the flying cranes have folded their legs, tucking their toes under their belly feathers to warm them. Usually cranes fly with extended legs, and these seemingly legless, truncated birds look odd indeed.

At Bernardo we are able to draw closer to the cranes and geese than at Bosque. Our slow arrival by car stimulates the cranes to dance, perhaps as displacement behavior. They are slightly agitated, slightly nervous, and dancing seems the thing to do in response.

Bernardo is part of the complex of refuges along the Rio Grande between Socorro and Albuquerque. Much of the area is closed to minimize disturbance to wintering birds, but you can drive the 3.5-mile tour loop. Take exit 175 from I-25, and immediately turn north along the road (314) which parallels the interstate. Within a couple of miles you'll reach the entrance to the tour loop. The habitat here is more agricultural than at Bosque del Apache. Getting so close to these impressive birds is a real treat!
