Bright Spots in Northern California

Bullock's Oriole Male

Nature with its feathers and its viruses does not dance for our pleasure or pain.  Water does not need us to make a river. But we, of course, can both minimize natural suffering and enjoy natural beauties.

There are uncounted bright spots freshly arrived in northern California.  Spring blooms deck our yards and fields, and, in the bird world, subtropical migrants have returned, decked in their finest plumage.

Among the brightest are orioles.  Bullock’s oriole males sport brilliant orange breasts and faces; their topside is mainly black, including an onyx cap, eyeline, and chin, with contrasting bright white patches on their wings.  Females are yellow breasted, fading to a whitish belly; their backs are pale brown–the pale colors that help hide them and their nests, and so keep the species going.

And these beauties dance.  When I was six years old I was given a package of plastic animals, each about my pinky-length.  The mammals were cast in brown, the birds in blue. In less than a day I lost my instant favorite, the wily weasel.  Gradually I lost the others, roughly in order of how much I valued and therefore played with them. The last to go was a clunky blue thing identified as an oriole.

It did the orioles injustice.  They are not clunky. The uniform blue I could allow; it was the color of the plastic, and I knew nothing different.  But its statue-stiff stance belied the birds’ reality. More accurately, the Cornell Lab of Ornithology opens its description of these orioles with the word “nimble.”

Orioles are nimble in so many ways.  Our Bullock’s orioles dangle from the swaying tips of cottonwood and valley oak branches and weave there the hanging baskets that will hold their eggs and nestlings.  They glean insect meals from those same precarious twigs–or from larger branches, or trunks, or from spider webs, or brush on the ground. They are versatile, and also resourceful.  If they catch a bee, they’ll pull and discard the stinger before dining. If they catch a toxic butterfly, such as a monarch or pipevine swallowtail, they’ll bang it on a branch to extract just the insides and avoid the poisons stored in the butterfly’s skin.  Or they’ll eat fruit, creating juice by piercing the skin and opening their bills inside, and then lapping the mushy liquid with their long tongues. Or they’ll use those tongues at hummingbird feeders, where a modest perch and a broken-out floret can invite repeat visits.

Their flexibility extends even to their human association and naming.  For a while Bullock’s orioles had been lumped into a single species with Baltimore orioles; the two do hybridize where their ranges meet in the Great Plains.  Further studies, however, have separated them back into the two species that their different color patterns had originally suggested.

Besides being brilliant and nimble, these birds are fast.  To see them, listen for their harsh chatter mixed with melodious squeaking, and keep an eye to your taller trees.  Perhaps you will find one of their twig-end nests, a hanging basket the size of a big orange. After two weeks of incubation, both parents will tend the nestlings there, offering ready views of some of nature’s brightest beauties.

Wintu Audubon Presents Turtle Bay’s Education Birds – CANCELLED!

Turtle Bay Exploration Park’s animal show will focus on birds, native and far.  The bird World is very diverse, from the smallest of hummingbirds to the largest of eagles.  Like all animals, birds have adaptations to help them find food, shelter, water and mates.  Some have defensive adaptations to overcome the hunting adaptations of other animals.  We will look at a variety of birds and explore their different methods to survive.  Many of these birds will be free flying while others may demonstrate their unique abilities on the ground.

Wintu Audubon Presents Birds of Costa Rica

Join Larry Jordan, bird photographer and Wintu Audubon webmaster, for an evening with the many wonders of Costa Rica. Larry spent twelve days with Lifer Tours guide David Rodriguez, to tally 220 bird species and several interesting mammals, from Punta Uva on the Caribbean coast, to several national parks, a Ramsar wetland, at Caño Negro Wetlands, the famous Bogarin Trail in the Arenal region and a brief time along the Gulf of Nicoya on the Pacific coast.

A Gentle Beauty

Mourning Dove

Mourning Dove

As they say, it takes all kinds. That all-kindliness brings a variety of glories into the world. Some are brilliant, like orioles. Some are loud, like mockingbirds; or sing melodically, like finches, or raucously, like jays. Some just dignify life with a humble beauty and gentility. Consider mourning doves.

They don’t sparkle with rainbow colors. They dress in a soft gray-brown, adorned by just a few black dots and dashes, and, for the careful observer, tinges of peach and blue.

Nor do they flutter fancy plumes. Their feathers are smooth, gentling from head to tip of tail, unruffled. In flight their tails fan white edges. At take-off their wings whistle against the wind, an unvoiced call to their mates and perhaps a distraction to predators. But they flaunt no fancy flags.

Nor do mourning doves shout for attention like carnival barkers or buyers of computer screen pop-ups. They just coo a mellow refrain, the sorrowful song that gives them their name. Listen to that song: its apparent sadness sounds not so much like a complaint as an homage to beauty.

The doves are quintessential Americana, living all over the contiguous US. Like many other Americans, they do some seasonal travel, mostly north in summer and south in winter. They live in a variety of habitats, and like historical Yankees, they make do.

They thrive in fields with scattered trees, but they’ll make home in suburbia or deserts, too.

They enjoy a good meal, out-eating holiday revellers with daily consumption of 12-20% of their weight in seeds and grains. Don’t try that at home, or anywhere else!

They drink deeply, sucking in water without the need to tilt up robin-style for gravity’s assistance. If fresh water is not available, they will handle brackish.

Perhaps the rarest quality of mourning doves is in how they feed their nestlings, known as squabs. In a simple nest, just a flimsy platter of twigs, the mother dove lays two eggs. When the helpless squabs hatch two weeks later, feeding must begin. But tiny seeds do not carry to a nest as readily as insects, nor do they have the same nutrient quality, nor can squabs digest them. The solution?– Both parents have crops, and hormonal changes cause their crops to switch from food storage to lactation a couple days before the young hatch. This “crop-milk” consists of sloughed-off cells from the crop lining, and, like mammalian milk, it is high in protein, fat, and antibodies–just what the babies need. Both parents feed this milk, mouth to mouth, to their young newborns.

In all the bird world, only doves and pigeons, flamingoes, and male emperor penguins (the females are away feeding in the ocean when emperors hatch) have evolved the capacity to create crop milk.

With their nutritious jump on life, and up to six clutches per year in their varied habitats, mourning doves nearly keep pace with not just the losses that all birds of our time face, but the high ingestion of lead pellets to which grain-eaters are vulnerable, and an annual hunt of twenty million. They have declined only 15% in the last half century, a terrible statistic, but better than the 50% decline of field birds in general.

Mourning Dove

And through it all, these unassuming doves sustain a special place in human lore. Not flashy, but vital, they remain a gentle and enduring symbol of peace, a beauty we can all appreciate.
