From Chambers’s Journal in an article called “Norfolk Broads and Rivers” :

On some of the broads there is still to be seen an industry fast falling into decay—decoys with decoy ducks and dogs. These require to be worked with the utmost silence and caution. One winter-night in 1881 Mr Davies inspected in company with the keeper the decoy at Fritton. Broad. The night was cold and dark, and each, of the men had to carry a piece of smouldering turf in his hand to destroy the human scent, which would otherwise have alarmed the wary ducks. This made their eyes water; and the decoy-dog, a large red retriever, being in high spirits, insisted on tripping them up repeatedly, as they crawled along in the darkness bent almost double. The interest of the sight, however, when at length they reached the decoy, fully made up for these petty discomforts. Peeping through an eyehole, a flock of teal were to be seen paddling about quite close to them; while beyond these were several decoy-ducks, and beyond these again a large flock of mallards. The decoy-ducks are trained to come for food whenever they see the dog or hear a whistle from the decoy-man. The dog now showed himself obedient to a sign from his master, and in an instant every head among the teal was up, and every bright shy eye twinkling with pleased curiosity. Impelled by curiosity, they slowly swim towards the dog, which, slowly retiring, leads them towards the mouth of the decoy-pipe, showing himself at intervals till they were well within it. The keeper then ran silently to the mouth of the pipe, and waving his handkerchief, forced them, frightened and reluctant, to flutter forward into the tunnel. He then detached a hoop from the grooves, gave it a twist, and secured them by cutting off their return. This seemed the last act of the drama, and Mr Davies took the opportunity to straighten his back, which was aching dreadfully. ‘Immediately there was a rush of wings, and the flock of mallards left the decoy. ” There, now, you ha’ done it!” exclaimed the keeper excitedly. “All them mallards were following the dog into the pipe, and we could ha’ got a second lot.” We expressed our sorrow in becoming terms, and watched the very expeditious way in which he extracted the birds from the tunnel net, wrung their necks, and flung them into a heap.’ Few places now are suitable for decoys, for even life in the marshes is not so quiet as it used to be (pg. 274).

In Norfolk and Suffolk, there is a series of deep rivers that open up into something very much like a lake. These areas are called “the broads.” This area was home to a peculiar type of retriever called the “Norfolk retriever,” which has now become extinct. It was more like a liver water spaniel/retriever cross.

I have already written about red decoy dogs, which were not large dogs, and were never called retrievers. They are at the base of the Nova Scotia duck-tolling retriever breed.

The red color was a necessity for any decoy dog, for it mimicked the fox, which has also been known to toll in ducks near to the shore. For some reason, ducks are easily beguiled by a dog or fox’s playful antics, and if one is also using decoy ducks that have been accustomed to entering a trap, one can use both the dog and the decoy ducks to capture them. (More on the history of this method for trapping ducks can be found at the Poodle History Project’s page on the decoy dogs).

I don’t know exactly what sort of retriever was being used as a decoy here. It could have been anything. Perhaps it was aberrant red wavy-coat that would never be used for a shooting party but was biddable and “sagacious” enough to be trained as a decoy dog.

In an article in Dogs in Canada from this February, Col. David Hancock, MBE, writes about a dark golden retriever doing decoy work in East Anglia (the historic region that includes both Norfolk and Suffolk):

A Golden was quite recently used as a decoy dog in East Anglia, charming many visitors. So the next time you throw a stick for your Golden Retriever, you may be re-enacting the role for which the dog’s ancestors were greatly valued, not merely idling away time and providing exercise. We may not, in these sophisticated times, need all of the wide-ranging skills of our dogs, but each must be exercised and we should honour their innate desire to be active, their instinctive interest in hunting and their inherent talent for serving mankind.

I am not suggesting that the large red decoy retriever was a golden retriever, but if trapping ducks had remained a popular activity, it is possible that the yellow and red retrievers would have been entirely developed for this task.

That color may not have been fashionable for late nineteenth century and early twentieth century shooting parties, but on the Norfolk and Suffolk Broads, the dogs of this color did have a function.

Most of the decoy dogs were mid-sized reddish dogs, not big retrievers.

So the exact origins of this large red retriever are quite interesting.

The retriever of the 12th Lancers

From a Windsor Magazine article entitled “Animals That Are Soldiers” (Vol. 14):

“Jack,” the retriever dog of the 12th Lancers, also accompanied that regiment into active service. Jack is a thorough Lancer; he delights in the very sight of a lance, and barks joyously when he sees the regiment ready for the march, and promptly takes his place with the men in the ranks. It was said that, of all our cavalry, the Boers feared the Lancers most, and Jack certainly encouraged them in these views; one may well pity any enemy who tries to kill a 12th man with Jack in the neighbourhood. His hair is beautifully black and curly, and he is about as intelligent a retriever its anyone can find (pg. 264).

Jack was a “curly-coated retriever,” but I a bit cautious about giving him designation as a member of the curly-coated retriever breed.  One of my goldens had a coat that was quite similar to this. Indeed, she very strongly resembled Jack in build and coat that I was somewhat shocked at the similarity. She was a very curly golden, who even had a partial water spaniel topknot!

The 12th Lancers were an active unit during the Second Boer War (1899-1902). I don’t know of how much use Jack would have been combat, but he certainly would have been good company. And if the unit had to shoot wild game for their dinner, they could always rely upon this intelligent retriever.

Audubon on the opossum

From Ornithological biography, or, An account of the habits of the birds of the United States of America (1831) :

The pleasant days of spring have arrived, and the trees vigorously shoot forth their buds ; but the opossum is almost bare, and seems nearly exhausted by hunger. It visits the margins of creeks, and is pleased to see the young frogs, which afford it a tolerable repast. Gradually the poke-berry and the nettle shoot up, and on their tender and juicy stems it gladly feeds. The matin[g] calls of the Wild Turkey Cock delight the ear of the cunning creature, for it well knows that it will soon hear the female, and trace her to her nest, when it will suck the eggs with delight. Travelling through the woods, perhaps on the ground, perhaps aloft, from tree to tree, it hears a cock crow, and its heart swells as it remembers the savoury food on which it regaled itself last summer in the neighbouring farm-yard. With great care, however, it advances, and at last conceals itself in the very hen-house.

Honest farmer ! why did you kill so many crows last winter ? aye, and ravens too ? Well, you have had your own way of it; but now hie to the village and procure a store of ammunition, clean your rusty gun, set your traps, and teach your lazy curs to watch the opossum. There it comes ! The sun is scarcely down, but the appetite of the prowler is keen ; hear the screams of one of your best chickens that has been seized by him ! The cunning beast is off with it, and nothing now can be done, unless you stand there to watch the fox or the owl, now exulting in the thought that you have killed their enemy and your own friend, the poor crow. That precious hen under which you last week placed a dozen eggs or so, is now deprived of them. The opossum, notwithstanding her angry outcries and rufflings of feathers, has removed them one by one; and now, look at the poor bird as she moves across your yard ; if not mad, she is at least stupid, for she scratches here and there, calling to her chickens all the while. All this comes from your shooting crows. Had you been more merciful or more prudent, the opossum might have been kept within the woods, where it would have been satisfied with a squirrel, a young hare, the eggs of a Turkey, or the grapes that so profusely adorn the boughs of our forest trees. But I talk to you in vain.

There cannot be a better exemplification of maternal tenderness than the female oppossum. Just peep into that curious sack in which the young are concealed, each attached to a teat. The kind mother not only nourishes them with care, but preserves them from their enemies; she moves with them as the shark does with its progeny, and now, aloft on the tulip tree, she hides among the thick foliage. By the end of two months they begin to shift for themselves; each has been taught its particular lesson, and must now practise it.

But suppose the farmer has surprised an Opossum in the act of killing one of his best fowls. His angry feelings urge him to kick the poor beast, which, conscious of its inability to resist, rolls off like a ball. The more the farmer rages, the more reluctant is the animal to manifest resentment ; at last there it lies, not dead, but exhausted, its jaws open, its tongue extended, its eye dimmed; and there it would he until the bottlefly should come to deposit its eggs, did not its tormentor at length walk off. ” Surely,” says he to himself, ” the beast must be dead.” But no, reader, it is only ” ‘possuming,” and no sooner has its enemy withdrawn, than it gradually gets on its legs, and once more makes for the woods (pg. 455-456).

Now, that’s some good nature writing!

I don’t think Audubon recognized that opossums also ate vegetation, but it is interesting that he recognized that human depredations against wild birds– in this case, crows and ravens– often drove the opossum to raid the chicken coops.

I don’t know how much opossums rely upon the nests of corvids for their sustenance, but this observation does suggest a certain level of ecological awareness on the part Audubon, even if it may not be entirely correct. In this analysis, Audubon clearly thinks that a human activity– shooting too many crows and ravens– causes the opossum to raid hen houses.

I don’t know if it’s true or not, but it does show a rudimentary sense of ecological understanding on the part of Audubon.

Not something one would expect from someone writing in the early part of the nineteenth century.

Classifying human species

Source.

I have often wondered what it would be like to live in the same area as another species of the same genus as mine (Homo). It would be even more interesting if this other species were chemically interfetile with mine, but we rarely hybridize for various reasons (perhaps the women are too ugly.)

Most North America and virtually all Central American dogs know what this is like. Coyotes are generally chemically interfertile with dogs, but not all coydogs are able to reproduce. However, they are more likely to be fertile than other hybrids.  Hybridization is actually not that common between dogs and coyotes, but there is evidence of dog genes entering the wild coyote population. It is not enough to say that many coyotes are hybrids. It is more accurate to say that there are coyotes that have dog genes in the same way that many modern humans of non-African decent have some Neanderthal genes. That does not make these non-Africans modern human/Neanderthal hybrids.  It just means that there was a hybrid somewhere in the ancestry.

It is often said that coydogs are rare because of the breeding cycles of coyotes is very fixed, and dog and coyote hybrids tend to diverge from the normal coyote breeding season. That may have something to do with it, but I think there is a bigger reason:  Most dogs hate coyotes.

Even the friendliest and most social dogs– the ones that readily play with other dogs– often view coyotes are the lowest form of canine existence. Miley hates coyotes but loves other dogs. I was actually surprised at her reaction to coyotes as she matured. I have no idea what causes dogs to hate coyote so much. Miley has had no bad experiences with them, so it must be something intrinsic to coyotes that brings out her antipathy.

Coyotes do have a different odor than domestic dogs, but that alone wouldn’t account for the behavior. If you put lots of doggy cologne on a normal dog, most other dogs won’t respond aggressively toward him.

I think it may have something to do with the coyote body language, which is very different from dogs.  Coyotes regularly use a threat gape, which is very different from the dog’s snarl. It is likely that they have other body language differences that just set dogs off.

Perhaps this was the case with early modern humans and Neanderthals. The two species may have been able to interbreed, but they rarely did so.  Of course, no one would ever suggest that coyotes and dogs were the same species, but it is possible that humans and Neanderthals were the same species– just very different subspecies. If we recognize only one species of wolf that includes the dog and the dingo, then we can see how one could possibly see the Neanderthal as a specialized Pleistocene member of our same species. Such classification has been rejected in the scientific journals, but we clearly recognize species that have as much diversity in appearance and genetics as existed between early modern humans and Neanderthals.

I’m still going to call Neanderthals a separate species, but I still think these questions have not been answered. Humans and Neanderthals aren’t much different than dogs are from the specialized big game hunting wolves from northern Eurasia and North America.  Of course, there has been more of a gene flow between those wolves and dogs than there was between humans and Neanderthals– and because both wolves and dogs still exist, the gene flow continues today.

Supposedly, Sir Walter Scott’s gun dogs and terrier

This is a painting of what are supposed to be Sir Walter Scott’s dogs.  The painting is by George Armfield and was said to have been painted at Abbottsford, Sir Walter Scott’s home, in 1852. The black dog at the center is said to be Maida, Scott’s favorite deerhound.

On closer inspection, one clearly sees that this is a painting of some gundogs and a small terrier-type dog.

The lemon and white dogs with feathering are either undocked spaniels or setters. These red and white or lemon and white spaniels were occasionally undocked in Armfield’s day, and they were the most common land spaniels in the British Isles during the eighteenth and early nineteenth century. The Clumber and the Welsh springer are likely descendants of these dogs. (Some authorities call these dogs Blenheim spaniels, but I avoid doing so in order to avoid confusion with a the red and white coloration in the two English toy spaniel breeds.)

However, there were also heavily built setters that were found throughout Great Britain during this same time period.  Whatever they are, they are of interest to anyone curious about the history of gun dogs.

In the background, two pointers are evident. These two dogs have shorter hair. One is black and white, and the other is liver and white. Both of these were relatively common colors in pointers.

However, the dog in the foreground is clearly not Maida. We have a very good idea of what she looked like. She was a cross between what we would today call a Great Pyrenees and a “deerhound,” which could mean any sort of large sight hound that was used to pursue game. Judging from the various depictions of Maida, the deerhound ancestor was probably a smooth sight hound of some sort, perhaps what was known as a “deer greyhound.” If the deerhound had been rough-coated, as all Scottish deerhounds of today are, she would have inherited this feature. She is more robust than any sight hound and she has an evident partial ruff, both of which she likely inherited from her Pyrenean sire. Cross-breeding mastiff-type dogs with large sight hounds was a common practice for producing a great “deer dog.” Many deer greyhound lines had a touch of this ancestry.

The dog in this painting obviously is not a large sight hound at all.

It is a retriever. The dog looks like it could be an early wavy-coated retriever or a St. John’s water dog (“Labrador”) with long hair. There never was a clear division between the two dogs, so either answer would be correct. It’s a retriever, not a sight hound, and it cannot be Maida.

I do not know if these dogs are actually the ones belonging to Sir Walter Scott. I have read no record of him owning any kind of retriever, although he did have a Newfoundland as a young man.

Of course, there is one other rather large reason to doubt that these dogs belong to Sir Walter Scott. The painting dates to 1854. Scott died in 1832.

So who knows whose dogs they actually were!

Still, it is a very good depiction of an either an early wavy-coated retriever or a long-haired St. John’s water dog.
