eBird, v.1895

Posted by: | Comments (0)

Bar graphs are so much a part of birding publications nowadays, e- and paper, that it’s tempting to think they were always there. They weren’t: only in the past thirty years or so, and largely thanks to its use in the ABA/Lane guides, has the bar graph passed from a welcome novelty to an expected component of finding guides and local ornithologies.

That’s not to say, of course, that such things are entirely new.

Lynds Jones bar graphs

In 1895, having taken up his position at Oberlin, Lynds Jones decided to publish the results of five years’ “systematic study of bird migration” in central Iowa. Over five full pages, he arranged 110 species in the sequence of their usual springtime arrival:

In these charts an attempt has been made to indicate not only the dates of arrival and departure … but the time of arrival or departure, or both, of the bulk of each species. This is indicated by the heavier portion of the lines opposite the name of each species, the lighter portion indicating simply its presence….

Was Jones the first to publish bar graphs showing the seasonality and abundance of birds? Let me know if you have any earlier examples.

Green Heron 2

In 1912, Harry C. Oberholser set out to sweep the Augean stables of green heron taxonomy,

to clear away, as far as the present material will permit, the confusion now existing with regard to the relationship and distribution of the various races… with their intricate relationships and rather peculiar geographical distribution.

Of the eighteen subspecies Oberholser claimed to be able to distinguish, only four have stood the test of timebahamensis from the eponymous islands; frazari from southern Baja; anthonyi of western North America; and the nominate virescens of eastern North America and middle America south to Panama.

Oberholser’s splittery may belong to the past, but one conclusion reached in his revision still rests its dead hand heavy on the list of American birds.

We owe the standard scientific binomial of the green heron to Linnaeus himself, whose Ardea virescens appeared in the Systema naturae of 1758, the first edition to “count” in zoological taxonomy.

It’s a good description:

a heron with a somewhat crested rear crown, a green back, a rusty breast….

The Linnaean statement of range at first strikes us as a bit vague: this bird “lives in America.” But it makes sense if we look at the ornithological sources on which Linnaeus based the name.

Catesby Green Heron Pl and txt 80

Mark Catesby had recorded the bird in Carolina and Virginia, while Hans Sloane and John Ray had prepared their descriptions — the former English, the latter Latin — from a specimen taken, it would appear, in the West Indies.

“Habitat in America” seems a reasonable way to describe the composite range of so widespread a bird.

Oberholser, however, knows better.

In his 1912 revision, he writes that “Linnaeus’s diagnosis fits only the green heron,” as do, obviously, Catesby’s text and plate. But Ray and Sloane, on the other hand, “without much doubt” in fact recorded not the green heron but the least bittern.

Oberholser concludes that

This makes Catesby’s description the sole basis of [Linnaeus’s] name, and since most of his [Catesby’s] birds came from the coast of South Carolina, it seems best to restrict the type-locality to that region,

thereby excluding Sloane’s and Ray’s contributions to the Linnaean project.

Oberholser’s restriction is still treated as authoritative in the latest edition of the AOU Check-list:

Screenshot 2015-01-18 13.55.11

But was the bird described by Ray and by Sloane really what we know today as a least bittern?

Both those authors describe the bird, apparently a specimen dissected by Sloane on his tour of the West Indies, as “fourteen Inches long from the point of its Bill to the end of the Tail,” with a wing span of about 20 inches — a bit on the small side for a green heron, but largish for a least bittern. Critically, neither remarks on the whitish or tawny panels so conspicuous on the spread wing of the least bittern, but they do note that the wings have “some whitish and tawny Spots here and there,” as in a non-adult green heron. None of the bittern’s distinctive wing and back pattern is apparent in Sloane’s illustration.

Sloane, Green heron

Oberholser’s characteristic confidence notwithstanding, there is no reason not to believe, with Linnaeus, that Ray and Sloane were both describing the bird we know as the green heron. Thus, the limitation of Linnaeus’s sources to Catesby and the consequent restriction of the type locality to coastal South Carolina (which Oberholser had already managed to sneak into the 1910 edition of the Check-list) is, if not wrong, then at the very least unnecessary. I say we should give Sloane and Ray their due, too.

Ardea virescens Linnaeus, 1758, Syst. Nat. (ed. 10) 1:144. Based on “A small Bittern,” Ardea stellaris minor Ray, Syn. meth. avium, 1: 189.4; on “The small Bittern” Ardea stellaris minor Sloane, Voy. Isl. 2: 315; and on “The small Bittern,” Ardea stellata minima Catesby, Nat. Hist. Carolina 4: 80, pl. 80. (America = West Indies and Virginia and South Carolina.)

Catalonia in January II

Posted by: | Comments (3)

We decided to go not quite so far afield the next day, and settled on the stunning mountain of Montserrat as our destination.

Rick at Montserrat

Getting there was half the fun indeed. The drive was easy and fast, and we transferred to the mountain train to take us up to the monastery complex.

Montserrat

The cliffs are high enough and massive enough to create their own weather: it had been warm and bright down below, but much of the morning was damp and chilly — never rainy, never cold — as we wandered the streets and admired the buildings raised over the centuries.

There are a few medieval remnants, such as this fragment of the Gothic cloister

Montserrat cloister fragment

and this strikingly flamboyant door:

The basilica itself was rebuilt at the end of the nineteenth century, incorporating some Gothic elements and a few Romanesque remains, most of the latter pretty badly weathered.

Long an important station on the route to Compostela, Montserrat still draws large numbers of pilgrims eager to see the Romanesque “black” Virgin and Christ Child, which perches high in a gallery above the choir. The line was long, but it was worth getting to see what is essentially the national statue of Catalonia.

We had lunch, then, as skies turned blue, got on the funicular to be dragged farther up the steep mountainside.

Montserrat

It was pretty breathtaking up there, the sparsely vegetated rocks and cliffs perfect for all sorts of alpine birds come spring.

An early January day didn’t have much appeal for the birds, unfortunately, though there were plenty of robins and black redstarts, as partout. We’d meant to check out the little cemetery behind the train station on our way back down, but I decided it might be more fun to spend the last couple of hours of daylight back in sunny Barcelona. We wound up taking a nice walk atop Montjuic, looking down on the city as the light turned soft and dim.

The next morning, refreshed and well breakfasted, we decided to drive west. It was a pretty morning in Barcelona, but not far out of town we ran into fog, then freezing temperatures, then a bit of mist, and more fog. We pushed on anyway, hoping the weather would clear.

It didn’t.

Lleida drylands

We left the highway before Lleida to explore some promising-looking agricultural areas. Once we were out of the traffic and driving dirt roads through the countryside, the weather seemed suddenly less grim: it was no different, but without trucks bearing down on us from both sides, we could enjoy the soft light and the wide-open views. There were even a few birds. Little gangs of red-legged partridges emerged from the fog here and there, and impressive flocks of chaffinches and linnets swept from hedgerow to field and back.

It was cold enough that we spent most of the morning in the car, stepping out now and again to confirm that the wind was still biting and the air still damp. Our plans to walk around the lake at Ivars were abruptly canceled when I found that I could hardly stand without shivering. I got no sympathy when I e-mailed home that night to poor Alison in New Jersey’s 8 degrees.

A hot lunch sounded like the better part of discretion, after which we headed back to Barcelona. Fog, freezing temperatures, a bit of mist, and more fog — and then we emerged from it all into another warm, bright, still afternoon, just perfect for a little sightseeing in town.

Sagrada Familia

We hadn’t been to the Sagrada Familia yet, so zipped over there and stood in line for a few minutes to get in. I’d expected irony, preciosity, even a little bit of kitsch, and was bowled over to find the place in fact beautiful and moving.

It wasn’t hard to hear the echo of Santa Maria del Mar in the treatment of the vaults, and I understood, as no photograph could make me understand, how well this church — still a-building thirteen decades after it was begun — fits into the architectural and spiritual history of the city. Even full of tourists (and this in early January), it is a quiet, reflective, inspiring place. See it if you can.

Culturally sated, it was time for dinner.

Barceloneta beach at night

We met Malte in Barceloneta for an evening stroll and a good meal, then back to the hotel to watch the day’s events replay behind our eyelids.

The drive through the fog had put me off motoring for a while, so the kids and I spent the next day wandering through Barcelona on foot. It’s a big city indeed, but if not for our overpowering need to get out of it to see birds, it would be easy to stay two or three weeks without ever using any mode of transportation but shoe leather.

We started off on the beach in Barceloneta, watching the sun rise and the black-headed gulls wake up.

Then it was on to Barcelona’s Gothic Quarter and, eventually, the city’s fourteenth-century cathedral.

That west front is a bit over the top.

Barcelona Cathedral

The interior, too, seemed less successful than Santa Maria del Mar, stumpier, less well articulated, more ponderous. There are some pretty capitals outside, though:

And the little cloister was a lot of fun, with palm trees, a large Nativity scene, and a dozen white graylags paddling noisily around on a cistern.

We ended the day up on the Montjuic again, this time, though, with plans for an all-out assault on the National Museum of Catalan Art.

Two hours later, I had to admit that the very first hall — Romanesque wall paintings and (a very little) sculpture — had vanquished me. We’d been warned that it was a big collection and that one really couldn’t just glance, nod, and walk to the next object; sure, sure, I thought.

Well, really.

You begin to get the idea. This is a museum that demands repeated visits (the ticket office knows it, too: one ticket gives you two admissions). I’m going back as soon as I can, armed this time with lunch.

I was exhausted, but not so much as not to enjoy another good dinner, this time on one of the smaller ramblas in the Gothic Quarter. I don’t think I could ever intentionally find the restaurant again — but much of the pleasure of Barcelona, we were discovering, was coming across the things you didn’t know you should be looking for.

It’s unclear how it happened, but the next day was already our last together in Catalonia. Malte met us at the hotel and we headed north as the sun rose to our right; by the time we arrived in Bagà, on the edge of Cadí-Moixeró Natural Park, the bright skies and warm temperatures had, too, and as soon as we left the very helpful visitor center, we’d all begun to shed layers.

Chatel at Cadi-Moixero

The few miles up to the pass of Pal were beautiful, and the weather and the landscape drew us out of the vehicle every few hundred yards to check out a trail or path.

Birding Cadi Moixero

The kind staff at the visitor center had reminded us that the near-absence of snow would mean few birds, but we did run across a single little band of alpine accentors on the roadside near one of the ski shelters, a glimpse of what the road could be like on a more wintry day.

The pass was stunning.

DSC01345

I don’t remember seeing or hearing a single bird up there, but the rocky tundra must be alive in the springtime with wheatears and pipits and who knows what else. On our visit, the little patches of snow had drawn bipeds of another kind, with sleds.

Alpine at Cadi Moixero

Tempting as it was to join them, we went back downhill a bit to look for birds of prey against the rapidly warming sky.

Cadi Moixero

Our reward was lots of griffon vultures, some of them floating past just beneath us as we sat and soaked up the sunshine. Malte and Sara had seen a lammergeier on their last visit, but we weren’t that lucky; next time!

Cadi Moixero trails

We continued downhill to Bagà, where we’d been recommended a couple of woodland sites. One of them concealed this lovely little Romanesque chapel:

The surrounding woodlands had singing coal and great tits, and we were surprised to see this pretty flower — the unpleasantly named fetid hellebore — blooming beneath the pines.

The shadows were lengthening, and we had an early morning coming up, so it was back to Barcelona, sorry not to have seen black woodpeckers and lammergeiers this time around but full all the same of what we had experienced on such a fine day.

We hadn’t been having any trouble getting up all week, but when you know that your destination is an outbound flight, it’s doubly tempting to spend some more time with the pillow. But we were up and out right on time, listening to the black redstarts sing in the dark as we walked to pick up the car. No traffic at all meant that we had the vehicle returned and ourselves checked in and securificationalized with plenty of time for one last quick breakfast together. Then Josh and Lizzie were off straight to Newark, me by way of Lisbon. Alison scooped us up as our various flights straggled in, and suddenly our vacation was over.

Good to be home, as always, and looking forward to the next visit to Catalonia. Thanks to Lizzie and Josh and Malte for a great week!

Two Parrots

Posted by: | Comments (0)

Parrots: There are too many of them, they’re too hard to see, and they all look alike anyway. At least these two are sitting still, which may — or may not — make them easier to identify.

Happily, Boddaert gives us Linnaean binomials for both birds.

Screenshot 2015-01-15 17.21.16

Psittacus galgulus does turn out to be easy: in spite of the bird’s upright posture on the plate, it is a blue-crowned hanging parrot. And yes, there is such a thing. This species owes both its scientific and its English names to the behavior described by Buffon:

this species is one of those that sleep head down.

Psittacus flavigula is less distinctive in appearance and in behavior. But thanks to the careful synonymies of John Cassin, we know that that name is a synonym of Phillip Ludwig Statius Müller’s Psittacus jugularis.

Screenshot 2015-01-15 17.35.21

Conveniently, Cassin also indicates the plate in the Planches enluminées from which Gmelin re-described the species (as tovi) in 1788 — and that plate is ours, number 190. Buffon himself describes it thus:

the head and all of the upperparts of this little bird are of a beautiful green, the throat of a beautiful orange color, the underparts entirely yellowish green.

Peters very neatly confirms the identification of this not very good portrait of an orange-chinned parakeet:

Now that wasn’t so bad after all, was it?
