Not a Slate-colored Junco! The Cassiar Junco

Cassiar Junco
Adult male Dark-eyed (Cassiar) Junco, Beaverton, Oregon, 7 April 2011 by Greg Gillson.
The bird above showed up at my feeder this week. Many birders might call this form of Dark-eyed Junco a Slate-colored Junco and not give it another thought. Technically, though, this is not correct.

Male Slate-colored Juncos are evenly dark gray above, with no contrast between head and back. This bird has an obviously darker gray head contrasting sharply with a paler gray back that is washed with a touch of brown.

The junco above is a Cassiar Junco. This was described as a subspecies of Slate-colored Junco when Slate-colored Juncos were considered separate species from Oregon Juncos. But in the Great Lumping of 1983 1973*, most of the juncos formerly considered separate species were lumped into "Dark-eyed Junco." Thus birders "lost" Oregon Juncos, Slate-colored Juncos, White-winged Juncos, and Gray-headed Juncos from their lists.

So if you saw a bird like this before 1973 it would have been considered a subspecies of Slate-colored Junco, and you could accurately call it such. However, since then, Oregon Juncos, Slate-colored Juncos and this Cassiar Junco are all subspecies of Dark-eyed Junco. So, technically, it is not a Slate-colored Junco. It is a Dark-eyed Junco or Cassiar Junco, but it is not a Slate-colored Junco.

I know, only 8 people in all of North America care. What? Not that many?

Looking at this level of detail will help you become a better birder--and you can do it in your own backyard.

Cassiar Junco
Immature (probably female) Cassiar Junco, Beaverton, Oregon, 28 March 2011 by Greg Gillson.
The male Cassiar Junco joined a first winter female that had been hanging around for a couple of weeks. Female and first-year Cassiar Juncos are much more difficult to separate from Slate-colored Juncos, so I was glad to spot the adult male.

The scientific name of Cassiar Junco is Junco hyemalis henshawi (=cismontanus of AOU 1957).

Cassiar Juncos breed in the Rocky Mountains of Canada. In winter they regularly are found from southern British Columbia east to Michigan and from there southward from Arizona to Texas. Scattered individuals wander widely in winter outside this main area.

Both Slate-colored and Cassiar Juncos can be found in small numbers throughout the Pacific Northwest in winter. They aren't too unusual at backyard feeders--most feeders will host a couple during the winter. But next time you see a "Slate-colored Junco" I bet you'll be taking a second, closer, look!

* The Great Lumping of 1983 1973: Besides the juncos, other species lumped in 1973 were Myrtle and Audubon's Warblers into Yellow-rumped Warbler; Red-shafted, Yellow-shafted, and Gilded Flicker into Common Flicker, but Gilded Flicker subsequently given back its status as a species and the other two called Northern Flicker; Baltimore and Bullock's Oriole lumped into Northern Oriole, but this decision was later reversed. Finally, Gray-crowned, Black, and Brown-capped Rosy Finches were all lumped into Rosy-Finch, but then this was reversed later, too, but with "Rosy Finch" altered to "Rosy-Finch." ...And I hear rumors of Yellow-rumped Warblers being re-split in the near future. -- We may get most of the pre-1973 species back, but the damage to birders' psyches from that period will never be repaired.

Casting the first stone

Benson PondI just know there's a Sora in there--give me a stone! Benson Pond, Malheur National Wildlife Refuge, Oregon, 26 May 2007 by Greg Gillson.

 

"A sharp keek when a stone is thrown into the marsh."
A Field Guide to the Birds. 1960. Roger Tory Peterson.
When Peterson was a young man, the accepted way to watch birds was along the barrel of a shotgun. Being a good birder a hundred years ago meant being a good shot. One also had to be skillful skinning and preserving the study skins procured. Rather than binoculars and spotting scope, a good birder had to carry a sharp knife and 2 pounds of arsenic to prepare the specimens.

Of course, by 1960 when Peterson was publishing his twenty-seventh impression of his second revised and enlarged edition of his famous field guide, shooting was out, and watching was in.

Thus, the introductory quote above of the voice of Sora, the secretive marsh rail. How many marshes did I fill with stones in my youth--at the suggestion of the greatest bird watcher of all time--hoping to hear a Sora call out?

As we approached the end of the 20th century, however, more thought was being given to the well-being of birds over the perceived "right" to observe birds.

It was about this time that the American Birding Association started up. Its goal was the advancement of birding, which was strongly slanted toward listing and chasing and definitely doing what it took to "get" the bird.

Nevertheless, in recognition of the growing concern for the welfare of birds, they crafted a code of birding ethics:
"Everyone who enjoys birds and birding must always respect wildlife, its environment, and the rights of others. In any conflict of interest between birds and birders, the welfare of the birds and their environment comes first."
Thus, Peterson's field guide changed with the times:
"When hands are clapped, startled birds utter a sharp keek."
Western Birds. 1990. Roger Tory Peterson.
So there we go. In one generation birding went from blasting birds with a shotgun to applauding.

This emphasis on the welfare of birds was certainly good.

But, sadly, it didn't end there.

In recent years there has been a growing theme in the various birding listservs and blogs. If we truly care about birds, this sentiment reasons, we won't guzzle up fossil fuels to find one out-of-place feathered waif. We won't use tapes for audio playback of a bird's song to get a better view. We shouldn't even pish!

In fact, if taken to its logical conclusion, if we truly care about birds, we should stay home and not go out and disturb them by watching them at all!

I think this is very faulty reasoning--and not a lot of fun, either.

Bird watching, even if accompanied by occasional fossil-fuel wasting, tape playback and, God forbid, pishing, creates more people who care about and protect birds and the environment than people who ignore it!

If I gave up bird watching, could I really replace it with an activity that disturbs birds less, in the long run? What should I do instead of "disturbing" birds by watching them--cruise the streets or hang out at the mall?

I submit that my peculiar habit of watching birds, and occasionally pishing them in for others to view, has caused numerous "non-birders" I encounter to notice birds and the world around them in an appreciative and protective way.

Yes, bird watching may slightly "disturb" some birds. But cutting down the forests, filling wetlands, paving over meadows, and creating shopping malls for people who don't even know the birds are there, disturbs more birds more greatly than all the tape playback, pishing or, yes, even stone throwing, by all the bird watchers in the world.

Look at those blue feet and legs!

Do you remember how to separate Hutton's Vireos and Ruby-crowned Kinglets?
