Come on, couldn’t they please start with an easy one?

Western Plaintain-eater, Pl enl 478

Like most of the participants in the recent Parade of Plumage contest, I cringed when I saw the very first image up for identification: What on earth could that be, and how on earth would I figure it out?

Boddaert to the rescue:

At least now — no thanks to the typo in the page number, which should in fact be 275 — we can see what Buffon had to say about the plate prepared for him by Martinet:

The bird called “tanas” by the inhabitants of Senegal, presented to us by Mr. Adanson under the name “fishing hawk” (see number 478 of the Planches enluminées), resembles our [peregrine] falcon almost entirely in the colors of its plumage: but it is slightly smaller, and on its head it has long protruding feathers, which fall back to form a sort of crest, thanks to which this bird can always be distinguished from others of the same kind: it also has a yellow bill, less curved and thicker than that of the falcon; it differs further in the very clear notches of both mandibles, and its habits are also different, fishing rather than hunting….

Not overly helpful. But Boddaert also gives us a binomial name, Falco Piscator, and a quick look at the Richmond Index gets us started.

The trail grows warmer with a simple google search. In the Novitates zoologicae for 1924, no less an authority than Ernst Hartert rehearses the taxonomic history of the bird in the Martinet plate:

Falco piscator Boddaert, Tabl. Pl. Enl., p. 28, is a name bestowed on Daubenton’s pl. 478, on which is represented a bird from Senegambia, obviously meant for our old Chizaerhis africana. I was at first inclined to reject this plate, because the tail is much too short, but as Mr. Sclater pointed out to me the peculiar bill is quite characteristic, the colour on the whole agrees well, and the tail is much foreshortened; the bill and the long occipital crest are well described by Buffon, and we must therefore overlook the much too rufous colour of the head, the shortness and the colour of the tail, and the descriptions of the habits, which were really meant for a bird of prey, but carelessly applied to this plaintain-eater.

Hartert follows Bannerman in assigning the bird on plate 478 the name Crinifer piscator (Bodd.); the genus name Crinifer, “crest wearer,” coined in 1821 by F.P. Jarocki, has priority over what Hartert calls “our old friend Chizaerhis” and, obviously, is to be preferred over Boddaert’s Falco.

Avibase then confirms that Crinifer piscator is still, 90 years later and over Peters’s objection, the bird’s correct name; it is known in English as the western plaintain-eater. Absent a physical specimen, the plate from the Planches enluminées serves as the formal type.

Happily, number two in the contest was easier.

Congratulations to Susie Haberfled for taking first place in the Parade!

Birds or Words

Posted by: | Comments (0)

Over at the ABA blog, where it is suggested that I am one of those birders

least concerned with what you call a bird. They are the ones who are distressed that a chicken hawk was chasing the snowbirds from their feeder.

Good stuff. What’s your take on what is intended as a serious argument?

And by the way, what do you think of the two images I selected as illustrations?

The Bishop of Bergen’s Birds

Posted by: | Comments (1)

Erik Pontoppidan den Yngre.jpg

Two hundred fifty years ago today, on December 20, 1764, Erik Pontoppidan — bishop of Bergen and father of Norwegian natural history — died in Copenhagen.

Pontoppidan was more than a bit of a polymath, and his publications range from theology and church history to biology and linguistics. Birders know him chiefly for two works, the First Essay on the Natural History of Norway and the Danish AtlasIf I’ve counted right, his are the scientific names we still use for eight species of birds, among them some of the best-known and most widespread northern breeders of both hemispheres.

Red-throated Loon

The red-throated loon is stellata for the sprinkling of white stars on the juvenile’s back.

Rough-legged Hawk

The rough-legged hawk is lagopus for its furry tarsus.

The rusty underparts and head of the adult curlew sandpiper’s alternate plumage give it the name ferruginea.

Pontoppidan focused not on the width but on the shape of the broad-billed sandpiper’s bill when he named it falcinellus, the little scythe.

American Herring Gull

He almost certainly translated from a vernacular name in calling the herring gull argentatus, for the silvery back of adults and older immatures.

Audubon Arctic tern

I’m at a loss, as seems to be everyone else: What is so heavenly about the Arctic tern? My own suspicion is that in naming this lovely, long-tailed seabird paradisaea, Pontoppidan meant to suggest that this species was the “northern bird-of-paradise.” It’s a nice thought, at least.

Pontoppidan’s aalge is simply the name in his native Danish for the common murre; the word is cognate with “auk,” “Alke,” “alcid,” and all those other back-throated names for black and white diving seabirds.

The taxonomic history of the short-eared owl (and of many others) is tangled, but to Pontoppidan goes the honor of having given it the name flammeus, apparently a reference to the bird’s overall tawny color.

And now a quiz to celebrate today’s anniversary:

Where would you go if you wanted to see all eight of these Pontoppidanian birds in a single day? Is it even possible?

Ruddy duck

The New Jersey Meadowlands were chilly and dim this morning, but the birding was a lot of fun anyway. There were impressive numbers of waterfowl on the marshes and impoundments, among them a dozen ruddy ducks, one of the few anatid species whose numbers in the mid-Atlantic seem to be declining.

Not only is this chunky, big-headed duck one of our most attractive, it also provides the answer to any number of birding trivia questions:

Which New Jersey duck is named for a Caribbean island?

Which duck lays the largest eggs for its body size?

Which male duck has ….

Well, we’ll leave that one right there. But there’s still the matter of this captivating species’ official English name, a name commemorating only a briefly held plumage of only one of the sexes and far less evocative than almost any of the dozens of other, popular names this duck has borne.

Screenshot 2014-12-16 16.27.48

The canonical diagnosis of this species was published by Gmelin in 1788, who named it Anas jamaicensis:

A duck barred dusky and rusty yellow, sooty above with a dark crown, the chin and throat white spotted with black, the vent and rump barred dusky and reddish.

Obviously, Gmelin did not assign this duck the English name “ruddy,” but he does cite an earlier description, in John Latham’s General Synopsis. Gmelin, it turns out, had simply translated the English account, which Latham based on what sounds like a non-breeding male. Neither ornithologist, obviously, had any notion of the spectacular breeding plumage of the species; indeed, Latham tells us expressly that his Jamaica specimen was taken in the winter, when ruddy ducks aren’t.

And now things get interesting. If we move forward through the editions of the Systema, we find the name “ruddy duck” in Turton’s English translation of 1802 — where it’s applied to a different bird.

Screenshot 2014-12-16 16.48.32

This is clearly a description of the ruddy shelduck; for our bird, Turton — like Gmelin — uses Latham’s rather unimaginative “Jamaica shoveler,” a name that we might still be using today had Alexander Wilson not made what he thought was an exciting discovery in Peale’s Philadelphia museum: a

very rare Duck was shot, some years ago on the river Delaware, and appears to be an entire new species.

Wilson Ruddy duck vol 8, p 128

Wilson was “at first inclined to believe” that his new duck was identical with Latham’s Jamaica shoveler,

but a more careful examination of both satisfied me that they cannot be the same, as the present [species] differs considerably in color…. front, crown, and back part of the neck down nearly to the back [are] black; rest of the neck, whole back, scapulars, flanks and tail coverts deep reddish brown, the color of bright mahogany.

That description confirms what Wilson’s engraving already demonstrates: namely, that one of Peale’s birds was a male in his bright breeding plumage. I think we can forgive Wilson his error in deciding that the Philadelphia ducks were “non-descript,” a deficiency he remedied by naming them himself in the pages of the American Ornithology.

Screenshot 2014-12-16 17.28.40

The drake’s mahogany upperparts were so striking that Wilson memorialized them in both the English and scientific names he assigned the species. And the names themselves seemed so apt that Latham’s “Jamaica shoveler” essentially disappeared after 1814.

Anas jamaicensis, however, would survive. Unlike vernacular names, scientific names are governed by the law of priority — also known as dibs: as soon as two “species” are known to be one, the first binomial is applied. So who figured out that the Jamaican shoveler and Wilson’s Pennsylvanian duck were the same?

Stay tuned.

Fuertes slat-colored junco

It’s one of the infallible signs of the season. Sitting inside on a chilly day, a cup of hot chocolate warming the hands and busy feeders cheering the heart, every year about this time you can watch it creep across the internet: the description of the slate-colored junco as “leaden skies above and snow beneath.”

I’d love to know who’s behind the e-revival of that particular bit of kitsch. Or do you suppose that everybody is quoting the phrase directly from its source, Howard Elmore Parkhurst’s The Birds’ Calendar?

Parkhurst, slate-colored juncos

Parkhurst’s “informal diary” is now virtually unknown — apart, of course, from that throwaway line about the juncos. But it marks the birth of a very special sub-genre in the literature of American birding, namely, the Central Park memoir.

The observations here recorded, with slight exceptions, were all made in that small section known as “The Ramble,” covering only about one-sixteenth of a square mile…. Within this little retreat I have, during the year [1893], found represented nineteen of the twenty-one families of song birds in the United States; some of them quite abundantly in genera and species; with a sprinkling of species from several other classes of land and water birds.

Among the birds Parkhurst encountered in January was

the snow-bird, a trim and sprightly creature about six inches long, dark slate above and on the breast, which passes very abruptly into white beneath, as if it were reflecting the leaden skies above and the snow below…. Their sleek and natty appearance and genial temper commend them at once to the observer.

Parkhurst, Birds' Calendar

And Parkhurst’s “attractive” prose commended itself equally to the contemporary reader. His felicitous description of the junco appears to have been quoted abundantly in the first two decades of the twentieth century, almost (only almost!) always with an attribution to the author. It seems likely that Neltje Blanchan was the earliest vector of dissemination for the phrase, which passed from her Bird Neighbors into leaflets for schoolchildren, who no doubt were as taken by “Mr. Parkhurst’s suggestive description of this rather timid little neighbor” as were his adult readers.

In the years that followed, however, the quotation was loosed from its authorial origins, most often to be cited anonymously. In his 1968 entry for the Bent Life HistoriesEaton followed that “modern” practice in noting only that the junco had been “aptly described as ‘leaden skies above, snow below'” — not bothering to tell us by whom. Parkhurst’s words still appeared in quotation marks, but they had plainly become part of a shared store of birderly lore, no more requiring attribution than the observation that the white outer rectrices are “prominent in flight.”

Ernest Thompson Seton, slate-colored juncos

This has always been the path of a catchy phrase: invented by a single mind, admired by others, then finally taken over into a broader culture eager to forget that it ever had an origin. But the internet has introduced another, more sinister step.

Parkhurst’s words still circulate — especially this time of year — without his name attached. In a classic internet move, though, a google search now, once again, turns up the quotation with an attribution.

A new attribution.

Thoreau described [juncos] as “leaden skies above, snow below.”

I don’t know all of Thoreau. I don’t remember those words in what I have read of the oeuvre, though, and it seems suspect to me that the earliest printed assertion of his authorship (thanks, google) should be from no more than four years before the Mother Jones quotation above. Surely in the 101 years between Parkhurst’s Calendar and 1994 someone would have pointed out the theft. I’m left wondering whether the credit to Thoreau isn’t — gasp — made up, as are so many (it sometimes seems like most) of the attributions on the internet.

It’s one of the unhappy elements of this e-world that it’s awfully easy for us to just say things, whether they’re true or not. But, in an encouraging paradox, the same casual convenience lets us go ad fontes in search of the truth: it takes hardly more time to look up “leaden skies and snow” than it does to decide to type the name “Thoreau.”

So here, a couple of weeks early, is my 2015 resolution: To give Howard E. Parkhurst credit for everything he said or wrote, and to resist the easy temptation to throw attributions around at random.

Who’s with me?
