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!

To distinguish these 2 large black fish-loving birds, see “Of Cormorants and Anhingas” (June 13th A.D.2019), posted at https://leesbird.com/2019/06/13/of-cormorants-and-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.)

OSPREY, The Migratory Piscivore

OSPREY, the Migratory Piscivore

Dr. James J. S. Johnson

While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.

Genesis 8:22

Migrating birds remind me of what God said in Genesis 8:22, about the predictability of annual seasons. It’s really amazing if you think much about it: God selected Moses to report a conversation that God once had with Noah, at the conclusion of the worldwide Flood. In that conversation God promised Noah (and Noah’s family and descendants, which include all of us) that God would not send another global deluge.

Rather, day-night periods would continue with constant periodicity, plus weather patterns would be stabilized with predictable patterns, such as the cyclical seasons we know as summer, autumn, winter, and springtime. God’s creatures depend on day-night cycles, as well as on annual cycles–such as the 4 seasons which provide predictability to growing and harvesting food crops (Genesis 8:22, quoted above).

But not only do humans depend upon such phenology patterns, so do animals–especially migratory animals, such as many insects and birds. One such migratory bird is the OSPREY (Pandion haliaetus), also known as the Fish Hawk.

Although not all ospreys migrate, most do, according to Donald & Lillian Stokes, A GUIDE TO BIRD BEHAVIOR, volume III (Boston: Little Brown & Company,1989 ), pages 169-170. In fact, most ospreys of North America–such as those of the Chesapeake Bay region–are known for over-wintering in or near South America, regularly returning to North American ranges during spring:

The warmer temperatures have brought with them a familiar Chesapeake icon. Ospreys (Pandion haliaetus) occur in nearly every corner of the globe, but nowhere as abundantly as on the Chesapeake Bay.

Ospreys return to the Chesapeake every spring from southern wintering grounds. Their abundance in the Bay region is due to the availability of food: They feed exclusively on live fish.

Their curved, sharp talons and rough-soled feet are designed to hold on to slippery fish.

Large brown and white birds of prey, they’re about 2 feet long with wing spans of 4-5 feet. When in flight, their long, narrow wings take on the shape of an outstretched M.

Ospreys hunt by soaring over water, periodically hovering on beating wings to scan the surface for schooling or spawning fish. Upon sight of its prey, the osprey makes a spectacular dive. Folding its wings tightly, it descends swiftly and plunges feet first into the water, often submerging itself completely. Another technique is a shallow scoop for fish at the water’s surface.

In addition to food, the Chesapeake provides many favorable nesting areas over the water such as duck blinds, navigation markers or man-made nesting platforms. Offshore structures offer protection from predators like raccoons, and rapid detection and escape from danger. On land, ospreys may nest on high trees and utility poles.

Ospreys 3 years or older usually mate for life, and will use the same nest site year after year A recently reunited pair will begin the task of nest building or repair.

Thanks for that report, Kathy Reshetiloff–that report that repeatedly fits the return of spring. This year (A.D.2022) is no exception, according to a short report in the CHESAPEAKE BAY JOURNAL:

Standing watch over a channel marker, soaring above the water, effortlessly snatching a fish — ospreys are among the most recognizable bird species in the Chesapeake Bay region. And they have begun their annual springtime return from South America.

Staff writer, “A Sign of Spring: The Return of the Chesapeake’s Ospreys”, CHESAPEAKE BAY JOURNAL, 32(2):3 (April 2022).

The Osprey is a daytime-hunting raptor, like others hawks and eagles, seizing its prey after a successful chase. And for the Osprey, that hapless prey is most likely fish of some kind–more than 99% of the Osprey’s diet is some kind of fish!

However, according to the University of Michigan’s Museum of Zoology website “Animal Diversity Web” [ AnimalDiversity.org entry for Pandion haliaetus ], an extra-hungry Osprey might catch and consume rodents (mice, rats, voles, squirrels), lagomorphs (rabbits, hares, pikas), small birds, salamanders, snakes, juvenile alligator, or even carrion (e.g., dead opossum, deer carcass). But those are rare dietary choices for an Osprey, because they have earned their common nickname, “Fish Hawk”.

Ospreys are not bashful about seizing fish prey, whether those prey are near the water’s surface or whether such prey is well below the water’s surface.

[The Osprey] is the only raptor that plunges into water feet first to catch fish. Can hover for a few seconds before diving. Carries fish in a head-first position for better aerodynamics [for post-catch flying]. Often harassed by Bald Eagles for its catch.

Hmm. that last “kleptoparasitism” fact–about eagles robbing ospreys of caught fish–where did I read about that recently? Oh yeah, I saw something about that on the best birdwatching blog in the world, LEESBIRD.COM — https://leesbird.com/2022/05/17/a-fisherman-robbed-chapter-20/ .

It pays to be a regular reader of LEESBIRD.COM ! — thanks, Mrs. Lee Dusing, for the ongoing blessing your birding blog has been, for years, is now, and continues (God willing) to be. (And thanks also for your sterling service as an Adjunct Professor to ICR’s School of Biblical Apologetics, over the past few years.) But mostly, thanks for honoring the Lord Jesus Christ, (our Creator-Redeemer) and for continually blessing birdwatchers, like me, with the wonderful service that LEESBIRD.COM provides. : )
