Update: I have seen these before at Lowry Park Zoo – My mistake :(

We see Double-crested Cormorants very frequently here in Florida. At the San Diego Zoo, we were able to see the White-breasted Cormorants. These are another one of the Lord’s neat creations which He has given them just what they need for catching their prey. They belong to the Phalacrocoracidae – Cormorant, Shag family of which has 41 species.

Cormorants and shags are medium-to-large birds, with body weight in the range of 0.35–5 kilograms (0.77–11.02 lb) and wing span of 45–100 centimetres (18–39 in). The majority of species have dark feather. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been found to dive as deep as 45 metres.

The White-breasted Cormorant (Phalacrocorax lucidus) is much like the widespread great cormorant and if not a regional variant of the same species, is at least very closely related. It is distinguished from other forms of the great cormorant by its white breast and by the fact that subpopulations are freshwater birds. Phalacrocorax lucidus is not to be confused with the smaller and very different endemic South Australian black-faced cormorant, which also is sometimes called the white-breasted cormorant.

White-breasted Cormorant (Phalacrocorax lucidus) Sign SD Zoo by Lee

The sign at the San Diego Zoo shows this bird as a sub-species of the Great Cormorant (Phalacrocorax carbo), but the I.O.C. lists it as the White-breasted Cormorant (Phalacrocorax lucidus). “The white-breasted cormorant (Phalacrocorax lucidus) is a member of the cormorant family Phalacrocoracidae. Its taxonomic status has been under discussion for some decades and several questions still have not been definitively settled. Phalacrocorax lucidus sometimes is treated as a subspecies of the great cormorant, Phalacrocorax carbo lucidus. ” (Wikipedia) That helps explain the discrepancy.

I especially liked the chin on this cormorant. Thought is was interesting and different from our usual Cormorants. Also, this was a first time we have seen this White-breasted Cormorant in any of the zoos we have visited. So it gets added to the Life List of All Birds We Have Seen

“As its name suggests, the 80–100 cm long white-breasted cormorant has a white neck and breast when adult, and the white area tends to increase as the bird becomes more mature. In other respects it is a large cormorant generally resembling the great cormorant.”

Here are the few photos that I took of these birds.

But the cormorant and the bittern shall possess it; the owl also and the raven shall dwell in it: and he shall stretch out upon it the line of confusion, and the stones of emptiness. (Isa 34:11)

And the pelican, and the gier eagle, and the cormorant, (Deuteronomy 14:17 KJV)

Cormorants are one the birds mentioned in the Bible. See Birds of the Bible – Cormorant

I see that both my Life List of All Birds We Have Seen and my Birdwatching Trips need some work. That ought to keep my busy this summer while most of the birds took off to their northern nesting grounds, that and trying to work on vacation photos.

Birds of the Bible – Cormorant II

And the pelican, and the gier eagle, and the cormorant, (Deuteronomy 14:17 KJV)

In the first Birds of the Bible – Cormorant, it was mentioned that they are one of the “unclean birds” not to be eaten, they have their own desalination system, and that they have been used for centuries in the Orient to catch fish for fishermen. Now, let’s look into some more facts about this family of birds.

There are 36 Cormorants are in the Phalacrocoracidae Family of the Pelicaniformes Order. The family includes the Microcarbo genus (5) which has the Little Pied, Reed, Crowned, Little, and Pygmy Cormorants. The Phalacrocorax genus (21) includes Cormorants and Shags. The Leucocarbo genus (10) are all called Shags except for the Guanay Cormorant.

“There is no consistent distinction between cormorants and shags. The names “cormorant” and “shag” were originally the common names of the two species of the family found in Great Britain, Phalacrocorax carbo (now referred to by ornithologists as the Great Cormorant) and P. aristotelis (the European Shag). “Shag” refers to the bird’s crest, which the British forms of the Great Cormorant lack. As other species were discovered by English-speaking sailors and explorers elsewhere in the world, some were called cormorants and some shags, depending on whether they had crests or not. Sometimes the same species is called a cormorant in one part of the world and a shag in another, e.g., the Great Cormorant is called the Black Shag in New Zealand (the birds found in Australasia have a crest that is absent in European members of the species).” Apparently, they are just appearing after “their kind.” There is variation in size, names and colors, but they are all related.

And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. (Genesis 1:21-22 KJV)

Cormorant” is a contraction derived from Latin corvus marinus, “sea raven”. Cormorants and shags are medium-to-large seabirds. They range in size from the Pygmy Cormorant (Phalacrocorax pygmaeus), at as little as 45 cm (18 in) and 340 g (12 oz), to the Flightless Cormorant (Phalacrocorax harrisi), at a maximum size 100 cm (40 in) and 5 kg (11 lb). The majority, including nearly all Northern Hemisphere species, have mainly dark plumage, but some Southern Hemisphere species are black and white, and a few (e.g. the Spotted Shag of New Zealand) are quite colorful. Many species have areas of coloured skin on the face (the lores and the gular skin) which can be bright blue, orange, red or yellow, typically becoming more brightly colored in the breeding season. The bill is long, thin, and sharply hooked. Their feet have webbing between all four toes, as in their relatives.

They are coastal rather than oceanic birds, and some have colonised inland waters – indeed, the original ancestor of cormorants seems to have been a fresh-water bird. They range around the world, except for the central Pacific islands.

All are fish-eaters, dining on small eels, fish, and even water snakes. They dive from the surface, though many species make a characteristic half-jump as they dive, presumably to give themselves a more streamlined entry into the water. Under water they propel themselves with their feet. Some cormorant species have been found, using depth gauges, to dive to depths of as much as 45 metres.

After fishing, cormorants go ashore, and are frequently seen holding their wings out in the sun. All cormorants have preen gland secretions that are used ostensibly to keep the feathers waterproof.

Cormorants are colonial nesters, using trees, rocky islets, or cliffs. The eggs are a chalky-blue colour. There is usually one brood a year. The young are fed through regurgitation. They typically have deep, ungainly bills, showing a greater resemblance to those of the pelicans’, to which they are related, than is obvious in the adults.”

The Cormorants and Shags are another of the Lord’s fantastic creations from an All-powerful Creator.
