First Night, Halibut Point

 

Quarry reflections

Winter Solstice, 2020


Standing before the curtain-rise of New Year's Eve 2020, my thoughts jostle inescapably with the past and the future.



More people than ever have discovered Halibut Point State Park during the pandemic. They resonate with the open-air splendor of it. The administration tries to balance these numbers, these external forces, with the welfare of the Park's natural life. I remind myself that our native good fortune is not a private entitlement to land of the Commonwealth. I wince, and I grin.



My fellow citizens are discovering more about the brokenness and balm of solitude. Time will tell if new patterns take hold. Companions smooth the edges of disruption.



I have seen newness, daring, hilarity leap over mountains to meet the sky.


Red-eyed Vireo


Winter has just begun. Daylight has been lengthening steadily since the solstice. The makings of song build in the fragile, ineffable processes of renewal.



Earth, water and sky wait to see what people will attach to the threads of their being.



Partners gaze on the fierce gifts of revelation and the molecular work of obedience.



I inhale elemental scripts mirrored in the stillness. Granite glides over water, improvising spectral breath. Players disrobe and dissolve time. Ticket holders write roles on the tissue of yearning. A thousand nativities whisper communion with ancient alphabets. The curtain rises on a kaleidoscope of creation.

The Charlie Brown Tree

 

White fir tree and barn, Halibut Point


There's a praiseworthy evergreen specimen near the Park entrance. This White fir is not a native tree, but was perfectly sited in the meadow for adequate sun and space to fulfill its symmetrical destiny. It towers over the old barn that has seen better days.


Charlie Brown and Snoopy


The scene calls to mind a Peanuts cartoon portraying tender feelings for an orphan Christmas tree. But these two pictures reverse the pathos: Snoopy's doghouse looks better than our sagging barn.

 

The cedar tree
(Eastern Red Juniper)

However, by turning around, I face a real-life orphan tree alongside Gaffield Avenue, the Park's entry road. I always go up to this tree on arrival to see what might be perched in its branches. The cedar planted itself, on a collision course with misfortune. Its upper half has been carved away by utility companies trimming around power lines. Its gappy skirt is laced with snow.


An Eastern Wood-Pewee


Sometimes birds find the cedar-wreathed wires a convenient station for hunting insects.


Ruby-throated Hummingbird


Others inspect the tree regularly on summer days for tidbits in the foliage,


Black-throated Green Warbler

or find nourishment within its ecosystem during spring migration.


Chain saw work


The tree lives at the borderline of nature and human enterprise, just as the Park itself does.


Blue-gray Gnatcatcher


Its carved-out canopy affords glimpses not so easily visible elsewhere. I wait for quick movements of interior busyness. 


Red-breasted Nuthatch



Golden-crowned Kinglet


Dark-eyed Junco



Cowbird


Birds send out mating calls when their time comes to be conspicuous on the tree spires. 

Grape vine


Around the Park cedars thrive in the early stages of forest succession from abandoned pasture land. The maturing woodlands tend to engulf the pioneering cedars. A grape vine reaching across Gaffield Avenue from this vegetative melee threatens to enshroud the tree.


Red squirrel


The vine provides an aerial highway to a squirrel crossing the lane to test the ripeness of pears at the top of a tree that is disappearing within the returning forest. Fruit trees are another remnant of domesticated land.



This cedar gets a reprieve from reforestation due to its roadside location, and to regular mowing of the meadow. It is a sentinel of hospitality.



Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.

Matthew 25:40

The Economics of Flight, 1 - Shoreline Formations

 

Razorbills

Last winter I received an interesting response to Notes from Halibut Point # 333, "Alcids and Evolution" from train engineer Alan MacMillan regarding seabirds flying close to the water.

I can't remember if I told you this or not, but I'm a pilot (single engine land, single engine sea ratings)....ALL seabirds that you see flying close to the water are flying in what is known in aeronautical terms as "ground effect," flying at an altitude above the surface (water, here) of 1/2 the length of their wingspan (for example: if a bird's wingspan is 2 feet, flying at 1 foot above the water.) Doing so requires HALF the energy of flying at altitude.

Alan went on to relate the story of a B-29 bomber experiencing loss of power to three of its four engines en route from Hawaii to San Francisco, yet conserving aerial buoyancy for the final 300 miles of the flight by descending to an altitude of 70 feet above the Pacific.

Surf Scoters and Red-breasted Mergansers skim the sea

In this marvelous era of the Internet I pursued Alan's insight to an article * published from Loyola College of New Orleans, where people marvel at Brown Pelicans soaring within the troughs of waves. The same ground effect, or compression gliding, comes into play when the bird is within its full wingspan of the surface. Efficiency increases as it nears the water and has everything to do with the relative length of its wings. Birds with long, narrow wings like skimmers, petrels, albatrosses, and shearwaters, which spend their lives far at sea, have not surprisingly evolved the most beneficial designs. 

As these birds glide over the water the air is funneled between the lower surfaces of the wings and the upper surface of the water. The compressed air functions as a cushion that supports the bird aloft, in addition to the normal aerodynamic forces at work. The phenomenon is most efficient over calm (flat) water. 

Pilots coming in for a landing are suddenly buoyed upward by the ground effect when they get within half a wingspan of the runway. As a passenger you may notice a buoyant sensation just before touchdown. Watch the glide of a landing duck. It often extends improbably long before feet finally meet water, in part due to help from the ground effect that softens splashdown into a gently controlled crash.

Energy-saving factors sometimes bring birds of different species to combine in formations for mutual benefit. We will look at some of these in the next posting.

Bluebird Friends - and Enemies

I rubbed my eyes on November 29 at the appearance of eight Bluebirds around the meadow at Halibut Point.

The flock vindicated Peter Van Demark's report the previous week of a special sighting for the Brookline Bird Club's monthly Sunday outing. 

Eastern Bluebird

Some of the birds "posed" obligingly on the mast of Purple Martin gourds in the middle of the meadow. What were they doing here at this time of year? Indeed, they are an unusual appearance at any time, in my experience.

The Bluebirds' interest in the gourds brought to mind some earlier incidents and ironies. A dedicated team managed nesting boxes for them in the spring. November is not nesting season, however. Perhaps the birds were looking for winter shelter. A fellow from the Boston area once told me he found several Bluebirds bundled together in a bird house on a frosty day in his back yard. Are we in for this kind of luck?

House Sparrows

Occupation by aggression has kept the Purple Martin gourd array under the control of House Sparrows ever since it was put up four years ago. Tree Swallows have also tried to nest in them but are always driven away by the sparrow gang. Since the recent demolition of the Silva House, condominium central for the sparrows, they seem even more determined to hold on to the gourd array.

with nesting intentions

Around the perimeter of the meadow are the four Bluebird nesting boxes installed this spring. The project originated with Ann Banks satisfying a requirement for her Audubon Birding Certification Program, coupled with the interest of Park Interpreter Ramona Latham. To keep the boxes free for Bluebirds they had to ward off the Tree Swallows displaced from the gourd array by the sparrows.

House Wren a-building

Lo and behold, House Wrens turned out to be the most determined competitors in the Bluebird boxes. The wrens would set to rebuilding their nests within minutes of cleanout by the box vigilantes, who interceded daily with firm views on good and evil. The bantam invaders have a dastardly reputation for destroying the eggs of other cavity nesters, and they chatter (sing?) incessantly.

November 29

Just prior to our current blustery weather the Bluebirds inspected the nesting boxes inside and out, unexpectedly rewarding their housing benefactors and the rest of us as well.

Flight Calls

What better way to have doors opened in your world than to come across a collection of good stories about it, that give you pithy and amusing keys to entry? West Gloucester raconteur John Nelson makes friends as he writes. He and his field companions attune themselves to the rigor and etiquette of birding quests, then share broadly over after-hours beverages. In Flight Calls John pulls under one cover a series of his published essays from literary as well as natural history magazines. The result is delightful reading both for the seasoned birders who will recognize typical characters and capers, and the armchair audience enjoying congenial, erudite adventures by the fireside.


John describes himself as "an enthusiast, but just a moderately competent birder." You might sample his chapters morsel by morsel around the demands of a busy life or, like me, read straight through in captivation. The stories take you from whimsy to science, from sunshine to frostbite, from delightful rambles to mobilizing for preservation of the natural world. You'll be motivated to sharpen your antennae for nature's wonders in your own back yard that might have gone unnoticed. 

One day I heard a whistling above me, familiar but feeble, and found a Broad-winged Hawk family. Two adults watched keenly as their single offspring tested its wings in short, wobbly flights, calling repeatedly and glancing toward its parents, like a child on a first bike ride without training wheels. These birds were placing me, deepening roots. 

John came to birding late. A collegiate track athlete, he pursued sports in the ensuing decades until he "started accumulating surgeries." There you have his taste for vigor and wit. Add to this his career as a professor of literature, plus a lifetime interest in travel, and you have the raw material for zestful essays. The book sets out to explore the length and breadth of Massachusetts through birds. It also takes you to exotic eco-destinations, and into the heart of an observant romantic.

As his competitive nature made less and less sense in the sports arena John turned to biking for exercise. With his eyes and ears liberated from automobile confines he became more aware of birds, especially their songs and flight calls. He started bringing along binoculars. He noticed he wasn't biking very far, especially in May, because he kept stopping to look. Pretty soon he found Brookline Bird Club companions to pursue passions and quirks with good humor and desire, embracing "the world of nature with no strings attached."

John delivers a Cape Cod hummingbird saga with all the ingredients of birdwatching lust and camaraderie that characterize his tales. 

The oddest "chases" are backyard stakeouts, like the one for a vagrant Broad-billed Hummingbird frequenting a feeder in November in South Yarmouth, as if the cape were next door to Nueva Laredo. A few of us, all strangers, were there one morning when the bird showed up. We danced about as if we'd all bet on the same long shot at the track. Sometimes word leaks out of a rarity hanging around someone's yard, but the homeowner doesn't want a horde of binocular-wearing outlanders traipsing through the neighborhood, so, to our chagrin, birders are disinvited. But the South Yarmouth folks, thrilled by rare-bird serendipity, welcomed all visitors, arranged a semi-circle of viewing chairs, and set up a heat-lamped feeder cover to keep the hummingbird cozy in their yard. One winter day another cape homeowner saw me shivering in her yard, like some lost, hopeful beggar, as I waited out a Western Tanager. She gestured me inside, gave me a cup of coffee and a blueberry muffin, and set me up in front of her picture window. 

John commends Halibut Point as a productive, accessible destination among East Coast birders looking for winter sea birds forced south from frigid latitudes. The jutting promontory can also turn up great variety in the spring as a "migrant trap," a stopover in the Atlantic flyway for birds on their way to distant breeding grounds. At any time of year its particular geography might host a rarity such as the Northern Shrike he and his wife Mary were lucky enough to see here. 

A glance at his chapter titles reveals the human as well as natural landscapes that draw John's attention. "Watching Gulls with Emerson on Cape Tragabigzanda" explores our local cultural terrain. "Geezer Birding" pushes against the limits of aging. In "Death and the Rose-breasted Grosbeak" his outdoor encounters soften personal grief.




"Birds have helped me find and nourish the untamed child within...a restless, seeking child who needs to get out, gallop or hobble across a field, and explore his earthly home."
