Clover Creek Preserve

Western Meadowlark

Western Meadowlark

This preserve within the Redding city limits has a large, permanent pond with a marsh of cattails and reeds, shallow winter pools and uplands planted with oaks. We hope to see grassland species such as the Northern Harrier, Western Meadowlark, Say’s Phoebe and Western Bluebird, as well as a variety of ducks.

Meet at 8am at the preserve, 3705 Shasta View Drive, at the main parking lot. We will spend about two hours walking less than two miles on a paved trail. There is a port-a-potty located in the parking lot and a full restroom at the nearby Shasta Trinity Fly Fishers Club.

Contact trip leader Tricia Ford at triciathebirdnerd@gmail.com for more information.

Great Egrets don’t make sense – sort of

Great Egret with Cattle Egrets

Camouflage clearly makes survival sense. But Nature doesn’t settle for just one kind of sense. Out along river shorelines and on the damp fields of winter, great egrets are blatantly visible, as uncamouflaged as possible in head-to-tail white.

They’re large. They’re out in the open. They’re plainly visible. Shouldn’t they be dead?

Great Egret Reflection

A hundred years ago they almost were dead. Ninety-five percent of great egrets in North America were wiped out, and it was indeed because of their feathers. The fashion of the day was to decorate lady’s hats with their fancy plumes, and so the birds were slaughtered and plucked. The plumes are especially showy in breeding season, so the birds were often taken while they had chicks in the nest; the young of course subsequently starved. This avian massacre sparked the founding of the Audubon Society, whose emblem became the great egret. Those Audubon activists moved a responsive Congress to pass the Migratory Bird Act in 1913, and egrets and other feather-hunted birds quickly recovered.

An interesting side note on John James Audubon, who died half a century before the organization took his name in honor of his famed bird paintings: he was blind to birds’ conservation needs. According to Smithsonian Magazine “Audubon insisted that birds were so plentiful in North America that no depredation—whether hunting, the encroachment of cities and farmlands, or any other act of man—could extinguish a species.” Recent trends, of course, have shown him exceedingly wrong.

Nonetheless, although other birds are in decline, great egrets are flourishing. They are versatile, readily foraging in the shallows of marshes, riversides, or coastal shores for fish, or reptiles, amphibians, crustaceans, or insects; or hunting in the deeper water of protected bays by standing, toes spread, on floating kelp. Or they will move into fields and spear gophers or voles with their dagger-like bills. Their foraging flexibility allows them to shift from less productive habitats into livelier ones.

Beyond their feeding versatility, great egrets nest with flexibility, too. They nest in colonies with other egrets or herons; but they can nest alone, too.

The male starts to build a platform of sticks, high in a tree; or, as availability requires, at the top of a bush, or even on the ground.

He courts a female with displays of his fancy plumes and his long beak, which turns green at its base, and with tumbling flights and offerings of twigs. She, also dressed to impress, may return his displays and then help complete the nest. Together they incubate and feed a few chicks. Birds are not universal practitioners of civilization, however, and if food is tight, larger chicks may stab and kill their younger siblings. It takes a while for young egrets to develop the cooperation and tolerance their parents exercise.

There are always things we don’t know. Great egrets are large, and large birds often mate for life. But egrets also carry out extensive courtship, which can suggest the wooing of a new mate. Or, again, perhaps egrets are among those fine creatures who sustain courtship throughout their relationship. We just don’t know.
But we know that they survive and prosper without a bit of camouflage. It’s a beautiful thing that Nature supports more than what at first glance seems rudimentary.

Turtle Bay Provides Natural Wealth

It is the Thanksgiving season, and Redding has a special treat to appreciate. We have naturally what many cities spend a lot of money striving for: a place like Turtle Bay.

Sundial Bridge

On any temperate morning, and many others too, the Bird Sanctuary Loop is the hub for a stream of cyclists, dog-walkers, joggers, retired couples, friends, young families, and bird-watchers. Children gaze at green-headed mallards and study the giant webs of garden spiders.  Parents guide their children to the trailside as bell-ringing cyclists approach. Walkers watch jacketed fishermen float below them, their boats drifting, their lines in the water. In fall, when the weather is right, the trails and visitors can be showered with golden leaves.

This welcoming and well-traveled route lies in the heart of Redding, nestled inside a bend in the river that creates the maze of bywaters and peninsulas that, together with the main river channel, comprise Turtle Bay. The green and brindled landscape nurtures a complex of aquatic insects and snails, and the fish, river otters, birds, and fisherfolk they support. The riparian woods house red-shouldered hawks, woodpeckers, and the numerous birds that nest in the cavities they excavate.  Quiet inlets make restful wintering grounds for geese and hundreds of ducks including mallards, ring-necks, shovelers, and teal. Herons and egrets stalk the shallows, and kingfishers plunge into clear pools. Out in the river’s main current golden-eyes dive for bugs while grebes and red-coiffed mergansers chase fish. At Turtle Bay nature quietly offers a fundamental experience of life–its giving and its taking back, its patterning and variety, its beauty.

But the wealth of Turtle Bay is not just the bend in the river. The bay is part of a corridor. Just as the Bird Sanctuary Loop is part of the larger River Trail, the Bay and its wildlife are part of the flowing water and the riparian woods, upriver and down. Each fall thousands of yellow warblers follow the river, scouring the riverside trees for insects to fuel their long flights to wintering grounds in Central America. Tanagers flock through, the males’ flame-red heads eclipsing into their yellow-greens of winter, as they gorge on the ripened grapes espaliered on towering cottonwood trees–again, fueling long flights south. Swallows–the orange-rumped cliff swallows that build homes under the Sundial Bridge, the shining blue tree swallows and violet-greens that nest in old woodpecker holes, and the rough-winged swallows that make homes in weep-holes at the Bella Vista water intake, all capture insects on the wing, skimming the river surface or circling high in the sky, first here where they hatch and then all along the river as they migrate. Redding’s famous eagles have fledged twenty eaglets at Turtle Bay; they, too, travel the corridor, both seasonally and a few years ago to try nesting downstream at Riverview Golf Course, where they fledged young but lost three nests before returning to their more reliable home at the Bay.

Redding Eagles

So far the Sacramento River corridor remains largely free of commercial development, allowing clean bywaters and riverine woods to grow the bugs that feed the fish and birds and other riparian life. Upriver from Turtle Bay the woods still flourish up to the dams, perhaps most broken at Redding’s Rodeo grounds, where the thin riverside forest has received a strip of welcome
replanting. Downstream, aside from the development along Park Marina Blvd, the riverbanks are substantially verdant.

Now the city is considering selling land at Turtle Bay for commercial development. As this is written, the City Council is pursuing the land sale, while unofficially assuring that the Bird Sanctuary itself will be retained and spared the pavement, at least for now. Unfortunately, the biology of the Bay stands to lose regardless, because its life runs up and down the river.

City Council has seemed genuinely interested in getting public input: should the sights and sounds of riverside plants and wildlife be retained with permanent, broad setbacks for riparian woodlands?  Should development be kept to areas that are already paved, perhaps diverted to Park Marina? Will a dressed-up Convention Center and more restaurants draw the revenue of visitors from the Bay Area and farther off? Ultimately, will selling riverine public lands for development improve the quality of life for citizens now and in the future?  Your City Council wants to know what you value. You can reach them through cityofredding.org .
