Django and Junco

Sometimes our cat Django gives us the slip and darts outside, even though I have lectured him many times about why it's important that cats be kept indoors. He dives under the deck before I can grab him, shouting over his shoulder that he doesn't care if I want to keep birds safe. He just wants to go eat grass and drink filthy water out of a flowerpot.

But payback comes in the form of a fierce pair of juncos nesting somewhere in the yard. As soon as Django creeps out from under the deck, the two little birds perch above him and denounce him loudly. Chip! Chit! Chit! they scold, and he flattens to the ground, as much as an 18-pound cat can flatten himself. His ears stick out sideways. His gratitude, when I slide open the door, is immense, and he flees from the tirade to the safety of the back of the sofa.

Juncos are such exceedingly common birds that most people who pay scant attention to birds tend to lump them in with all the other little brown or gray things with wings that flit about the yard. They aren't really far off the mark in so doing--juncos are, after all, a kind of sparrow, and it's hard to get more common than a sparrow. (Well, depending on what sparrow you're talking about, that is.)

But I'd never seen one before I moved to the Northwest from the east coast more than 25 years ago. I quickly learned that this little gray and brown bird with the black executioner's hood was an Oregon junco--one of the many races of the species known as the Dark-eyed Junco, Junco hyemalis.

Actually, it would have been remarkable if I'd seen an Oregon junco on Long Island in New York; it's a western bird, found only casually in the East. What I would've seen back east was another race, the slate-colored junco. ("Casual" in birding doesn't mean that the bird is found in jeans and a tee-shirt leaning nonchalantly against a wall. It means "Species not recorded annually in the ABA [American Birding Association] Checklist Area, but with six or more total records—including three or more in the past 30 years—reflecting some pattern of occurrence." In other words, slim pickins.)

Dark-eyed juncos live year-round in many parts of the West, the Appalachians, and some northern states. In winter, they spill out to fill the rest of the country. This migratory habit earned them the common name of "snowbird." In warm states, the term would imply they're escaping winter's cold, but people in chillier states think of them as sticking around or arriving with the snow.

Juncos "drift into our gardens when snowy weather comes and when days are dark with rain, and winds blow cold," writes Francis Staver Twining in her book Bird-Watching in the West (1931). "I am always glad when the juncos come dancing in."

The juncos in our winter garden join finches, sparrows, towhees, and chickadees at our feeder. Though they're ground birds, they will also struggle to snatch seeds directly from the feeder, flapping furiously as they try to cling to its sides with one foot and grab something before they lose their balance.

A junco's crisp markings stand out nicely in a snowy scene. The Oregon junco male's head is jet black, and his gray-brown wings fold neatly to form lapels on his russet sides. The female has much the same coloring but in paler shades. Both have white feathers on either side of their tails.

These white tail feathers serve many purposes. If threatened, juncos flare their tails as they fly away so the white feathers can signal an alarm to other juncos, in the same way that a raised white tail signals alarm in a fleeing deer. At the same time, the flash of white tells a predator, "I see you, you missed your chance, you've been spotted, hunt something else." Observers have also seen juncos flaring their tails to threaten other birds, including other species, in crowded feeding conditions on the ground.

In courtship, male juncos flare their tails to show off the white feathers as they seek to win over a female. Scientists have found that birds receiving better nourishment grow feathers with bigger white patches than birds eating merely a subsistence diet. If so, it may be that bigger white patches = more pugnacious bird = female selection pressure on male juncos to have hunky white tail feathers.

Another study seems to show that suburban juncos have less white in their tails than rural birds; the speculation is that there is less predation and competition in suburbia, and so female selection pressure is leaning more toward having a mellow dad around to help with household chores than an aggressive warrior.

Just recently, when Django the Cat made an escape and I responded to the junco's angry cheeps by stepping outside to fetch him, I nearly trod on a male junco apparently leading him up the steps by scrabbling along the deck with his tail flared, much like a killdeer feigning a broken wing. I'd heard that the white tail feathers might also entice a predator into going after the junco's tail instead of its vital head and body, so it's not such a leap to imagine the junco might likewise use its white feathers to lure a predator away from its young.

The white tail feathers, the variety in coloration, and much more make the humble junco "a rockstar study organism" for scientists. These scrappy little birds have been used in studies focusing on evolution, speciation, migration, ecology, and other topics. There's even a movie about them that can be downloaded or ordered and used in schools, museums, and other venues (find it here).

I poked around in a few old bird books to see if I could find some fascinating tidbit about these backyard birds, but without much luck.

My old reliable Birds of California by William Dawson devotes much of its account to the parsing of junco species and races. The Audubon Society Encyclopedia of North American Birds gives workmanlike accounts of each race (with an odd note in the Oregon's write-up: "Juncos attracted to warmth of caves in Yellowstone have died there from gases").

John James Audubon, however, had lots to say about juncos, which he was glad to see in winter when they migrated into Louisiana.

According to him, the junco was apparently quite well known among people in the mid-1800s:
So gentle and tame does it become on the least approach of hard weather, that it forms, as it were, a companion to every child. Indeed, there is not an individual in the Union who does not know the little Snow-bird, which, in America, is cherished as the Robin is in Europe. 
And his description of its behavior tells you exactly why a junco can put the fear of God into a fat housecat:
Although the Snow-Birds live in little families, consisting of twenty, thirty, or more individuals, they seem always inclined to keep up a certain degree of etiquette among themselves, and will not suffer one of their kind, or indeed any other bird, to come into immediate contact with them. To prevent intrusions of this kind, when a stranger comes too near, their little bills are instantly opened, their wings are extended, their eyes are seen to sparkle, and they emit a repelling sound peculiar to themselves on such occasions.
Our resident juncos are currently spending a lot of time emitting repelling sounds, because they even shout at the cat when he's indoors if they spy him through the glass sliding doors. Meanwhile, the rufous hummingbird will divebomb the male junco if he happens to be sitting too close to the nectar feeder. Which makes the other cat, Pebble, utter that weird chittering noise cats make when they gaze at birds from a window. Which  makes the dog come in to see what's going on. It's a busy season, springtime is.

A Fling with Spring Bling, Part 2

A friend requested "more, please!" after my last posting about life reasserting itself in the garden upon the arrival of spring (this one's for you, JB ;) and now that we're halfway through the season, life has certainly reasserted itself with a vengeance.

A bamboo grew four feet tall in one week and other plants are working hard to keep pace. The hummingbirds consume the contents of the nectar feeder faster than my daughter's weighty truck swallows gasoline. Chickadees snatch every bit of fluff shed by the dog. Buttercups threaten to engulf the house.

Here's a few pix. Planning to spend as much time this weekend in the garden as possible, as long as the sun's out!

Just a Little Spring Bling

All in all it was a pretty mild winter, but it's still nice to be bidding it farewell and welcoming the first signs of spring.

Mornings now ring with the songs of Pacific wrens, Bewick's wrens, song sparrows, and varied thrushes, with percussion added by the flickers drumming on trees, streetlights, and metal gutters.

I went out to poke around in the garden to see what it's been up to since I bothered much about it late last fall.

Periwinkles are the first fireworks to bring a burst of color.

Flower buds on viburnum, waiting to unfurl.

A trio of mushrooms. Couldn't quite catch the curly woolly-lamb
look of their stalks because their whiteness blinded my camera.

Somebody was nesting up in the magnolia last year!

The earthworms are still sleepy and quite grumpy about being disturbed.


Miniature daffodils are wide awake and honking.


Rhubarb is growing by leaps and bounds and will
be ready for harvest within weeks. Pie!

Moss! Acres of moss! Sit still too long and you, too, can be covered with it.

A Bird in the Hand

Pacific Wren (formerly Winter Wren)
In recent weeks I've had the privilege of going behind the scenes at a museum to look at birds close-up in the form of study skins.

Poring over stuffed, dead birds might not sound like everybody's idea of a good time, but for birders it offers an excellent opportunity to observe details and compare and contrast species in a way you never get to do in the field, where birds often appear as silhouetted blobs on a brightly lit sky, a streaky dash amid branches, or a tiny speck beyond the reach of your binoculars.

A study skin is exactly what it sounds like: a bird skin complete with feathers, beak, and legs that's been stripped of all flesh and stuffed so that it can be measured and examined. The stuffing doesn't attempt to recreate the bird's form in life, as taxidermy does.

(For more information about preparing study skins, as well as some points of view on collecting birds, check out this ebird page.)

Sometimes wings are prepared separately from the study skins so they can be displayed fanned out, making individual flight feathers easy to see. A study skin wouldn't last very long if its wings were constantly being unfolded. The wings are actually threaded in place to prevent them from being spread.

A museum's collection of study skins includes the remains of many birds who were found dead and donated for preparation. (I once had a bushtit stored in my freezer for years after finding it newly dead on the sidewalk outside my house with this aim in mind.)

It also includes birds deliberately collected for study, though unlike the overzealous collectors in Audubon's time, today's scientists take legal and ethical considerations into account.

Handling and studying the skins evokes many feelings: wistfulness and a twinge of sadness at the stillness of the birds and the brevity and evanescence of life; humility at the connection between now and then, as you hold a tiny bird collected by someone who lived a century before you; and awe at the magnificent beauty and variety of species.

and reflect on both this little scrap of life that fluttered long before you
were born and the existence of the person who carefully penned
the information on its tag.
Orange-crowned Warbler. The study skins of smaller birds really
demonstrate how much of a bird's volume consists of the life pulsing
in it. This is particularly true of the wrens, which resemble empty pen
cartridges in the drawer but appear much larger in life when they're
full of spunk and fury and scolding you from a branch.

Hello, Kitties: The Paws That Refreshes

*Warning: Here be cat puns. If you cannot make dreadful, labored, and timeworn puns in an article about a cat cafe, when can you?

There's a new kit in town: it's Seattle's first cat cafe, Seattle Meowtropolitan, and it's located in Wallingford kittycorner to Archie McPhee's.

I met two friends there for coffee on a rainy Thursday afternoon.

Since moving to the suburbs, meeting friends for coffee is a rare event, unlike the reflex reaction automatic default it was in the city, where I couldn't step outside without tripping over the threshold of a coffee shop.

So I would probably have driven for much more than an hour to meet friends for coffee even if the cafe was boasting a playroom full of death adders.

At Seattle Meowtropolitan, ten dollars buys you a tasty coffee drink of your choice and 50 minutes in the cat room, which houses a dozen or more cats at a time.

I ordered a Meowca. I didn't ask for an extra chat, but I'm sure you could. The purristas were very friendly.



(Reservations must be made in advance because the number of humans is limited, and no one under age 8 is allowed in the cat room. However, you can also drop in to have coffee in the shop and just gaze through the window at the cats.)

There is a sign on the door to the cat room explaining the byclaws of the establishment and that you enter it knowing that you will encounter...cats. This would seem self-evident, but remember, this is America, land of litigation. You can't be too careful.

In the cat room, there are felines, nothing more than felines. And loads of cat toys. And wonderful structures for cats to climb, explore, and snooze on.

There are a few tables and benches for both humans and cats. We pussyfooted around the room, careful not to step on tails or toys, and visited kitties of all stripes and no stripes.

The cats come from a local shelter, and most are adoptable (there are a few resident cats). It's a great strategy for showcasing cats' individual qualities--the cats at Seattle Meowtropolitan were content and very much at ease.

If I didn't have two easily outraged cats and a boisterous dog at home, I'd probably have come home with this elderly orange tabby, who was grateful for a neck rub and rolled sideways to get a belly rub. Its back felt like a craggy mountain range beneath its thick fur, and it's nice to know this kitty will enjoy a pleasant retirement lounging on a sheepskin and basking in attention.



Some cats, like this big gray sleeping at head height, were not in the mood to have their naps interrupted, but they didn't get all fussed about it--they just gave you That Look.



The youngest cat, a cute little gray girl with white paws, was exhausted after a hard morning of playing.


An attractively marked calico exhibited an obsession with burrowing into piles of jackets and snuggling among them.

Another young cat preferred to do battle from a high perch.



This orange tabby knew how to sit on command and offer up either his left or right paw when asked. He was also clever enough to do whatever he pleased to get a treat when the treat-provider wasn't the cat-room employee.



The cats have plenty of places to escape from human attention so they don't get overwhelmed. There are boxes...



...and an off-limits "cats only" area in the back.



You can ponder the world according to cats in the bathroom...



...and there are also delectable treats to purchase in the cafe (you don't have to sit on command or raise your right paw to acquire them, though it would be polite if you refrained from jumping on the table to eat them).


We had a purr-fectly lovely time, of course, and it's definitely one of Seattle's most a-mews-ing coffee shops. And I'm not kitten around. I'm sure Abyssnian some friends there again.
