Beauty, Times Two

 

Week after week, I watched this pair of yellowlegs as they foraged back and forth across a shallow, grassy mudflat that developed after weeks of unusually heavy rains. I never saw them fly, and I never heard them call; they were too busy plucking indeterminate creatures from the sandy mud.

While they fed, I amused myself by trying to decide if they were greater yellowlegs (Tringa melanoleuca) or lesser yellowlegs (Tringa flavipes). There are ways for an experienced birder to distinguish between them — body size, the length of the bill, the nature of their call — but I never was certain which species I was seeing until the day something startled them. Calling to one another, they flew up and away from their buffet table.  A later comparison of yellowlegs calls convinced me they were Lesser, not Greater — but no matter which species, I found them a great delight.

A Beauty, Not a Beast

If beauty lies in the eye of the beholder, so, too, might ugliness. Underwater, the cormorant’s a swift, graceful predator: astonishing in its ability to glide and dive, sweeping up uncounted fish in the process. But once it exchanges the water for land, many consider the bird — songless, lacking in bright colors, awkward and somewhat ill-proportioned — to be as ugly as any on the planet.

When I had the opportunity to spend some time with a remarkably accepting cormorant recently, a closer look revealed some interesting, and even attractive, characteristics.


Its lightly serrated beak, hooked at the end, allows it to hold its prey firmly. Why this one continually opened and closed its beak while I watched, I can’t say; perhaps it was showing off for the camera.

Its long, flexible neck, capable of twisting and bending like a heron’s, allows it to preen even the most hard-to-reach feathers. Secretions from its uropygial gland, more commonly known as the preen gland, are composed of  a mixture of waxes, fatty acids, lipids, and water.

As the bird preens, rubbing the glandular secretions through its plumage,  some waterproofing may take place, but the primary benefit is to keep its feathers supple and in good condition. The familiar spread-wing posture cormorants assume when out of the water generally is agreed to be a method of feather drying.

For years, I saw cormorants only at a distance, and assumed them to be pure black. Instead, their feathers are a mixture of brown and black, with occasional flashes of iridescence. The brown head feathers, thick and velvety,  are especially attractive, and help to set off their turquoise eyes. Sitting eye-to-eye with such a placid and receptive creature is an uncommon treat.

Snowy Flurries

For some, changing colors on trees or shrubs provide a first hint of the coming fall. Here on the upper Texas coast, autumn arrives differently, flying in on the wings of migrating birds.

Teal arrive first, followed closely by peripatetic mallards. Last week, the calls of returning osprey began echoing across Galveston Bay. Yesterday I realized the swallows had flown away, but their space soon will be filled by an assortment of geese, raptors, and cranes.

While snowy egrets stay with us throughout the year, their numbers increase in the fall as birds return to their favored coastal marshes, inland mudflats, agricultural land, and drainage ditches.

Like the proverbial birds of a feather, they roost and nest together; last weekend I found a large flock hidden away along a canal in the Brazoria Wildlife Refuge.

Touching down

Sometimes referred to as ‘Golden Slippers’ because of their yellow feet, egrets also have yellow lores (the area between their bill and their eyes), which change to a deeper salmon or pinkish-orange during the breeding season.

Showing off, perhaps?

In the late 1800’s and early 1900’s, their plumes sold for nearly twice the cost of gold, and were used to decorate women’s hats. Inevitably, they were hunted nearly to extinction, but after the passage of laws meant to protect them, their numbers increased. Today, they’re a common sight: their golden slippers worth as much as any gold, and their developing plumes a hint of courtships to come.
