Cormorants are Great; Great Cormorants are Really Great!

Cormorants are Great; Great Cormorants are Really Great!

Dr. James J. S. Johnson

But the cormorant [shalak] and the bittern shall possess it [i.e., the land of Idumea, a/k/a Edom]; the owl also and the raven shall dwell in it; and He [i.e., the LORD, in judgment] shall stretch out upon it the line of confusion, and the stones of emptiness.

Isaiah 34:11

In some contexts, CORMORANTS are not deemed as indicators of blessing — as in Isaiah 34;11, where it is prophetically mentioned as an indicator that the land of Edom is catastrophically destroyed. However, in many other contexts, these magnificent birds are recognized as wonderful creatures whom God has equipped to live by bodies of water, both freshwater and seawater.

Cormorants love to live by bodies of water. Cormorants are found busy hunting — darting (befitting the Hebrew noun shalak, in Leviticus 11:17 & Deuteronomy 14:17, translated “cormorant”, which matches the darting-like targeting movements) for food over and near coastlines, including the coasts of islands, such as the Hebridean isle of Staffa, which was reported earlier (on this Christian birdwatching blog), in the report titled “Birdwatching at Staffa: Puffins, Shags, and more”, posted at https://leesbird.com/2019/07/22/birdwatching-at-staffa-puffins-shags-more/ (July 22nd A.D.2019), citing Isaiah 42:12. [Regarding “cormorants” in the Holy Bible, see George S. Cansdale, ALL THE ANIMALS OF THE BIBLE LANDS (Zondervan, 1976), at page 175.]

Cormorants constitute a large “family” of birds; the mix of “cousins” include Crowned Cormorant (Phalacrocorax coronatus), Brandt’s Cormorant (Phalacrocorax penicillatus), Galapagos Cormorant (Phalacrocorax harrisi), Bank Cormorant (Phalacrocorax neglectus), Neo-tropic Cormorant (Phalacrocorax brasilianus), Double-crested Cormorant (Phalacrocorax auritus), Indian Cormorant Phalacrocorax fuscicollis), Socotra Cormorant (Phalacrocorax nigrogularis), Cape Cormorant (Phalacrocorax capensis), Guanay Cormorant (Phalacrocorax bougainvillii, a/k/a Guanay Shag), Kerguelen Shag (Phalacrocorax verrucosus), Imperial Shag (Phalacrocorax atriceps), Antarctic Shag (Phalacrocorax bransfieldensis). South Georgia Shag (Phalacrocorax georgianus), Campbell Island Shag (Phalacrocorax campbelli), New Zealand King Shag (Phalacrocorax carunculatus), Bronze Shag (Phalacrocorax chalconous), Chatham Island Shag (Phalacrocorax onslowi), Auckland Island Shag (Phalacrocorax colensoi), Rock Shag (Phalacrocorax magellanicus), Bounty Island Shag (Phalacrocorax ranfurlyi), Red-faced Cormorant (Phalacrocorax urile, a/k/a Red-faced Shag), European Shag (Phalacrocorax aristotelis), Pelagic Cormorant (Phalacrocorax pelagicus, a/k/a Pelagic Shag), Red-legged Cormorant (Phalacrocorax gaimardi), Spotted Shag (Phalacrocorax punctatus), Pied Cormorant (Phalacrocorax varius), Great Cormorant (Phalacrocorax carbo), Japanese Cormorant (Phalacrocorax capillatus), Olivaceous Cormorant (Phalacrocorax olivaceus, a/k/a Mexican Cormorant), and Pitt Island Shag (Phalacrocorax featherstoni).

That’s a lot of cormorant “cousins”, worldwide! [For details on each of these “cousins”, see pages 116-136 of Jim Enticott & David Tipling, SEABIRDS OF THE WORLD: THE COMPLETE REFERENCE (Stackpole Books, 1997).]

Notice: Cormorants are not anhingas!

Cormorants are famous “fishermen” along ocean coastlines, yet cormorants also thrive in inland freshwater habitats, such as over and near ponds and lakes, such as the Double-crested Cormorants that frequent inland ponds in Denton County, Texas, where they catch “fish of the day”.

Cormorants are generally described, by ornithologist Roger Tory Peterson, as follows:

Large, blackish, slender-billed water birds. Often confused with loons, but tail longer, bill hook-tipped. In flight, wing action is more rapid and axis of body and neck is tilted upward slightly (loon’s neck droops). Young birds are browner, with a pale or whitish breast. Flocks [of cormorants] fly in line or wedge formation very much like geese but they are silent. Cormorants often perch in upright positions on buoys or posts with neck in an S [posture]; sometimes strike a “spread eagle” pose. Swimming, they lie low like loons, but with necks more erect and snakelike, and bills tilted upward at an angle. Food: Fish (chiefly non-game). Nearly cosmopolitan [in range].

[Quoting Roger Tory Peterson, cited below]

[See Roger Tory Peterson, A FIELD GUIDE TO THE BIRDS OF TEXAS AND ADJACENT STATES (Houghton Mifflin, 1988), page 10.]

Specifically, the Double-crested Cormorant (Phalacrocorax auritis) is perhaps the most common winter migrant of the cormorants; also, the Double-crested Cormorant is often seen in the coastline areas of Texas’ Gulf of Mexico shores.

Have you ever watching a silhouetted cormorant — or two — or three — winging their way across the late afternoon sky? It is a wonder to behold!

Now, try to imagine a dozen, or more, cormorants, flying in series. That’s a wondrous wonder to behold! That constitutes one of the “wonders without number” that Scripture refers to (in Job 9:10).

And now here is my closing limerick, about cormorants:

APPRECIATING HUMBLE CORMORANTS (AND SHAGS)

Cormorants are not known to brag,

If they’re so-called, or called “shag”;

They oft fly, in a line,

And on fish, they oft dine

But cormorants aren’t known to brag.

(Dr. Jim Johnson formerly taught ornithology and avian conservation at Dallas Christian College, among other subjects, and he has served as a naturalist-historian guest lecturer aboard 9 international cruise ships, some of which sailed in seawaters frequented by cormorants and shags. Jim was introduced to Christian birdwatching as an 8-year-old, by his godly 2nd grade teacher, Mrs. Thelma Bumgardner.)

AULD LANG BIRDWATCHING”* follows:


(Sing to the tune of AULD LANG SYNE.)

Should old birdwatching be forgot

    And lifers go unseen?

The fowl so fair, in air we spot

    Or perching as they preen.

 While drinking coffee, birds we gaze

    On earth, at sea, in sky;

God made them all, us to amaze,

    Birds run and swim and fly!

Black-headed Gulls and Great Black-backed Gulls: Birdwatching in the Scottish Hebrides, Part 4

Black-headed Gulls and Great Black-backed Gulls: Birdwatching in the Scottish Hebrides, Part 4

Dr. James J. S. Johnson

For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea. 

(Habakkuk 2:14)

The islands of Scotland’s Outer Hebrides are a familiar territory for various seagulls, including two in particular: (1) the largest seagull, the low-sounding “laughing” Great Black-backed Gull (Larus marinus); and (2) a much smaller yet loud-“laughing” Black-headed Gull (Larus ridibundus, a/k/a Chroicocephalus ridibundus).

Great Black-backed Gulls are large (more than 2’ long, with wingspan about 5’ wide; often males weigh up to 4 or 5 pounds, while females weigh slightly less), deserving their nickname “King of Gulls”. Thanks to God-given toughness these gulls can survive and thrive in coastlands of the North, breeding in parts of Russia, Scandinavia, along Baltic coasts, the British Isles, Iceland, Greenland, the Faroe Islands, plus the Atlantic seacoasts of Canada and America’s New England shorelines.  In winter many of these gulls migrate south.

In Nornian, the ancient Old Norse-derived language of the Shetland Islands, the Great Black-backed Gull was once called swaabie, from swartbak, meaning “black back”whereas in AD1758 Karl (“Linnaeus”) von Linné taxonomically designated theseseagulls as Larus marinus, denoting a marine seagull/seabird (from Greekλάῥος). In a previous study (titled “Birdwatching at Staffa, near Iona: Puffins, Shags, and Herring Gulls”), the Great Black-backed Gull was noted as a prominent predator of Atlantic puffins, yet this gull avoids puffins who nest near humans.

However, it is not just the Atlantic puffins that must beware the apex-predatory pursuits of Black-backed Gulls, because these gulls also prey on terns and many other birds, as well as almost any other organic food smaller than themselves, living or nonliving, if they can swallow it.  Accordingly, these scavenging gulls are attracted to garbage dumps filled with human wastes, as well as to egg-filled nests of smaller birds, plus available rodents (e.g., rats) and lagomorphs (e.g., rabbits).  Likewise, these bullies practice “klepto-parasitism”, i.e., aerial bullying-based robberies of food from other birds—when accosted by Great Black-backed Gull, the smaller birds drop their food—as the Great Black-backed Gull chases the dropping food, to capture it in the air, the robbery victim flies away to safety. 

During the winter months these gulls spend less time over land, because the sea itself then offers better opportunities for food—especially lots of fish!  Any fish who are close to the ocean’s surface are at risk when these gulls scout for catchable food. In fact, quantitative studies of their stomachs show that marine fish (such as herring) are the primary diet of Great Black-backed Gulls, although they also eat other birds (like herring gulls, murres, puffins, terns, Manx shearwaters, grebes, ducks, and migrant songbirds), plus small mollusks (like young squid), crustaceans (like crabs), marine worms, coastline insects and rodents, as well as inland berries, and lots of garbage and carrion (found in places as diverse as saltmarshes, landfills, parking lots, airport runways, piers, fishing docks, surface ocean-waters, etc.). 

[See William Threlfall, “The Food of Three Species of Gull in Newfoundland”, Canadian Field-Naturalist, 82:176-180 (1968). See also, accord, Kirk Zufelt, “Seven Species of Gulls Simultaneously at the Landfill”, Larusology (http://Larusology.blogspot.com/2009/11/7-species-of-gulls-simultaneously-at.html ), posted Nov. 15, 2009.]

Like the above-described Great Black-backed Gull, the gregarious (i.e., colony-dwelling) Black-headed Gull is notorious for its omnivorous scavenging and often-predatory habits, opportunistically frequenting oceans, intertidal beaches and estuarial coastlands, marshlands and other inland wetlands, lakes, rivers, and even agricultural fields. These gulls, as breeding adults, sport dark-chocolate (almost black) heads.

Black-headed Gulls can soar high in the air, swim in the ocean, and walk along a sandy beach—they are equally comfortable moving to wherever they want to go to.  These noisy seagulls sometimes appear to “laugh” when they call.  Like other seagulls, they enjoy eating fish—sometimes they dip their heads under the tidewater surface, while swimming.  When scouting along a coastal beach, these gulls probe for coastline critters (which they probe for and snatch).  Also, they are fast enough to capture flying insects, which they catch “on the wing”.

Gulls come in many varieties, plus some of these varieties are known to hybridize. For example, Great Black-backed Gulls (Larus marinus) hybridize with Herring Gulls (Larus argentatus). Black-headed Gulls (Larus ridibundus) often hybridize with Mediterranean Gulls (Larus melanocephalus), and also with Laughing Gull (Larus atricilla) and Common Gull (Larus canus).  Other hybrids exist, too, and many of these gull hybrids have been verified by genetics (i.e., DNA parentage verification).

[ As a boy this author watched seagulls, both inland and at seacoasts, with wonder. God made them all! A half-century later, I still watch seagulls (and many other birds) with wonder.  “He (God) does great things beyond searching out … and wonders without number.”  (Job 9:10) — God shows how wonderful He is! ]
