The new AOU Check-list supplement: more work for you speakers of Latin

A male Purple Finch pauses in mid-crunch to ask himself, "How do you pronounce Haemorhous, anyway?"

From Oak Harbor, Ohio, Kenn writes:  Every year now, birders in North America eagerly await the annual publication of the American Ornithologists' Union's Committee on Classification and Nomenclature - better known as the AOU Check-list Committee.  This is the committee of experts that makes the decisions about how our birds are classified, what is a full species and what is merely a subspecies, and what their official names should be.  Birders usually love it when a species is "split" (it could make our lists larger!) and hate it when two species are "lumped" (which could have the opposite effect).  And although the committee is not secretive about their deliberations, we never know for sure how things are going to turn out until the annual supplement in published, in the July issue of the AOU's journal, The Auk.

The supplement for 2012 has just appeared, and the changes this time are fairly conservative.  There's one split that increases the number of species recorded in North America north of the Mexican border, and no lumps this time.  The most notable changes are in the scientific names of several birds.  Those of us who enjoy memorizing these Latin names now will have to relearn several of them. 

First, the "split."  The little Pacific seabird called Xantus's Murrelet has been ripe for a split for quite some time: birders recognized that it had two populations with distinctly different face patterns.  Now those two will be regarded as separate species.  The one that breeds on islands off the coast of southern California and northwestern Baja, with a mostly dark face pattern, will now be called Scripps's Murrelet (Synthliboramphus scrippsi).  The one that breeds mainly on islands off of western Baja (and wanders north into California waters), with more white around the eye, will be called Guadalupe Murrelet (Synthliboramphus hypoleucus).

This split is well supported: both of these birds nest on San Benito Island off Baja without interbreeding, and they differ in face pattern, voice, and genetics.  The bad thing about the split, of course, is the loss of the name "Xantus's."  That could be a problem when we're playing word games with birds!

The other changes this time focus on changes in scientific names.  As ornithologists continue to learn more about relationships among birds, various birds are being moved from one genus to another.  Here's a brief rundown of just those name changes involving birds found north of the Mexican border.

Gray Hawk:
Buteo nitidus becomes Buteo plagiatus.
(Split from South American "Gray-lined Hawk," which keeps the name nitidus.)

Purple Gallinule:
Porphyrio martinica becomes Porphyrio martinicus.
(I know - earth-shaking, isn't it?)

Caprimulgus carolinensis becomes Antrostomus carolinensis.
Eastern Whip-poor-will:
Caprimulgus vociferus becomes Antrostomus vociferus.
Mexican Whip-poor-will:
Caprimulgus arizonae becomes Antrostomus arizonae.
(Sorry to see these taken out of the genus Caprimulgus, "milker of goats," because that was always a good name for weirding people out.  Incidentally, Eastern and Mexican whip-poor-wills were just split a couple of years ago.)

Calliope Hummingbird:
Stellula calliope becomes Selasphorus calliope.
(It always seemed as if it belonged with the Rufous types, and now it's official.)

Sage Sparrow:
Amphispiza belli becomes Artemisiospiza belli.
(Had been placed in the same genus with Black-throated Sparrow for a long time, but its different behavior, including its tail-bobbing and its habit of running on the ground with its tail raised, had suggested that it might not be a close relative.)

Purple Finch:
Carpodacus purpureus becomes Haemorhous purpureus.
Cassin's Finch:
Carpodacus cassinii becomes Haemorhous cassinii.
House Finch:
Carpodacus mexicanus becomes Haemorhous mexicanus.
(The latest information suggests that these birds are not closely related to the rosefinches, genus Carpodacus, of the Old World. The Common Rosefinch, which strays to Alaska, is still in its old genus.)

There are other changes that will affect your list if you bird south of the Mexican border, including changes in names of a number of wrens, an official split for the Galapagos Shearwater, and other alterations.  For the full text of the latest AOU supplement, here's a link:

One final note:  as Roger Troutman pointed out to me in an email, what could be considered the most significant change in the supplement is a change in the sequence.  Two major groups of birds - falcons and parrots - are being uprooted from their current position in the checklist, and moved to a completely different spot.  Falcons have been placed right after the typical hawks in the checklist sequence, and just before the cranes.  Parrots have been placed a little later in the list, after the doves but before the cuckoos, and still well before the owls, hummingbirds, swifts, and woodpeckers, all of which come before the huge group of songbirds.  Well - that's about to change.  Falcons and parrots are going to be placed after the woodpeckers, and just before the songbirds.

Say what?  Falcons not considered relatives of hawks?  Parrots considered to be practically songbirds?  This is going to call for a major shift in our thinking!  It also calls into question the practice of some field guides in slavishly following the official checklist order, rather than placing similar birds close together in the book.  I think I'll write something about that in a separate post.

The Next Birding Movie

From Oak Harbor, Ohio, Kenn writes:  Almost a year ago, I was contacted by a young filmmaker named Rob Meyer.  He said he was working on a feature-length film that would involve birding, and he wanted my feedback on the draft of the screenplay. 

Naturally I was interested.  At that time, we were all looking forward nervously to the release of the film of "The Big Year," wondering if it would simply insult birders (it didn't) or if it would become a smash box-office hit (it didn't do that, either).  The buzz about "The Big Year" had been going on for months, and birders were already starting to talk about the possibility that Hollywood might wake up and discover that we're out here. 

So I started corresponding with Rob Meyer.  Turns out, Meyer has a lot of experience, having worked on award-winning documentaries at PBS and National Geographic.  His independent short film "Aquarium" won awards at film festivals around the world.  But even someone with that kind of credentials has to work at it to drum up the financing for a feature-length film.  All of the details have to fall into place together.  He was very close to having it set to shoot in late fall 2011, and again in spring 2012, and key elements didn't work out.  Now, though, it looks as if all systems are Go.  The film, "A Birder's Guide to Everything," is set to start shooting just over a week from now, in late July 2012. 

I've read three drafts of the screenplay and have talked to many of the people working on the film, and I have to say I'm excited about its potential.  While I can't discuss details, the main character is a 15-year-old birder named David Portnoy, and a major part of the plot revolves around his sighting of an exceptionally rare bird (thought to be extinct, which is about as rare as you can get).  David and two of his teenaged birding pals, plus a girl who is just starting to get interested, go on a road trip to try to relocate the bird.  There's a lot going on for all of the characters, but the birding aspects are all taken seriously -- there's no mockery of birding, or of teenaged birders, in the screenplay.  I can't promise that every bird-related detail will be accurate (after all, this is a movie!) but I can tell you that Rob Meyer at least listens to his birding consultants and takes their ideas into consideration. 

And the film is just about to start shooting!  You can read about the process from the inside on a blog that's linked here. 
If you're on Facebook, the film has its own FB page here.

At the moment, the only members of the cast that I know about for sure are Academy Award winner Sir Ben Kingsley (not playing one of the kids, but rather a famous older birder) and Bryan Cranston (who played the dad on "Malcolm in the Middle," among other things).  I've been invited to go visit the set while they're shooting, probably in early August, so I might have more to report later.  In the meantime, if I can embed this video correctly, here's the "sizzle" reel put together to pre-promote the film:
