Memento Mori: Another Computer Shuttles This Mortal Coil

Contrived durability is a strategy of shortening the product lifetime before it is released onto the market, by designing it to deteriorate quickly. The design of all consumer products includes an expected average lifetime permeating all stages of development. Thus, it must be decided early in the design of a complex product how long it is designed to last so that each component can be made to those specifications.–Planned Obsolescence, Wikipedia

Last week our big, beautiful iMac computer passed away. In the middle of the night, funny orange dashes appeared across the screen. When I rebooted, blue stripes appeared and then faded to bright white. A few quick looks around the internet led to a few attempts to revive, but in my heart I knew  . . .  it was over. This was our bird photography computer . . . . 

A day or two later I took the lifeless hulk to the Apple Store Genius Bar so a technician could have a look. Sure enough, the video card had croaked. But then the technician kept talking (but not smiling) . . . He said that because the machine is over five years old (it was built in late 2009 by Chinese paupers and bought by us in early 2010), it is considered a vintage machine and Apple Stores will no longer service it. He said that even if he wanted to, he couldn’t work on such a machine because after five years the Apple stores ship all the replacement parts back to corporate.

Five years. Five years! After five years, a multi-thousand-dollar machine will not be serviced by its manufacturer. Sure, I could find a third party operation that might be able to fix it with “old” spare parts, but that’s a big “if.” Wow. Luckily we had ordered a replacement the night before. It will take ten days to arrive.

So, if you are planning to buy an Apple computer to service your bird photography addiction, then start saving for its replacement now. They cost about $3k and last about five years. Period.

A Birding Comedy of Errors

Until I know this sure uncertainty, I’ll entertain the offered fallacy.–William Shakespeare, The Comedy of Errors

Birding is something I do alone, with Elisa, or with very small groups of people—so the impact and embarrassment of personal screw-ups has been limited. Field blunders have ranged from the minor (like calling a female Orchard Oriole a Prothonotary Warbler in front of the late Steve Gross) to silly, like hustling out the woods in grizzly country feeling like I was being hunted only to decide that it was all in my head! Probably.

In the imagination-getting-the-better-of-oneself scenario, a week or so ago I was on the levee between 40-acre and Pilant Lake when I heard a loud rustling coming from the rice on the edge of Pilant Lake. Whatever it was sounded big—and it sounded like there were several somethings. Would I see a row of feral pigs? Otters? Raccoons? Otters would be great! This could be exciting! A similar thing had happened before and a bobcat had poked its head out less than five yards in front of me!

So I fiddled with my gear in eager anticipation . . . when who popped out? A group of the noisiest grackles on the planet emerged from the vegetation, and they had nesting materials in their beaks. At least I got a few shots of that, I thought disappointedly. Later, while reviewing the images, I realized that it was not nesting materials that they had, but straw-colored katydids! The birds must have been in a line to flush out the insects. Without knowing it, I had likely observed avian cooperative hunting. I have seen Cattle Egrets doing much the same thing. So much for otters.

In the not-knowing-what-you’re-looking-at scenario, last week I was watching American Goldfinches chiseling into stems of an unidentified plant and plucking out tiny somethings. That’s weird, I thought, what could these birds be getting out of stems? Later, I brought up the question to a naturalist friend, and he quickly offered that insects had possibly infested the stems and the birds were simply fishing them out. But later while reviewing the images trying to identify the “insects,” I realized that the stems were not stems at all, but rather dried-out elongated seed pods, and the birds were (unsurprisingly) simply eating seeds! The whole conversation about insects in stems was like the Peanuts episode when Lucy and  Linus wonder about how potato chips could migrate from Brazil (after misidentifying a potato chip as a beautiful yellow butterfly).

In my own defense, once in a while I see something unusual enough that I don’t feel silly when I misinterpret it. I remember photographing the Yellow-crowned Night-Heron below and feeling sorry that the poor animal had a growth on its lower bill. A few years later, while sifting through the archives I noted that it was not a growth, but rather a gar tooth that was protruding from the bill. The bird must have been hunting in the water when a gar bit it through the lower jaw. In the ensuing struggle, the tooth must have broken off.

Finally, this post reminds me of a question I often pose to myself: Do I see more when I am out photographing or when I am binocular birding? I’m pretty sure that I see more with binoculars alone because I’m not worrying about light, perspective, and so on. But then again, without images to check what I’ve been seeing, how do I really know that what I’ve been looking at it is what I thought I was looking at?

Birds Fishing at Low Tide

If the earth should cease to attract its waters to itself all the waters of the sea would be raised and would flow to the body of the moon.—Johannes Kepler, Astronomia nova (1609)

Among all the great men who have philosophized about this remarkable effect, I am more astonished at Kepler than at any other. Despite his open and acute mind, and though he has at his fingertips the motions attributed to the earth, he nevertheless lent his ear and his assent to the moon’s dominion over the waters, to occult properties, and to such puerilities.–Galileo Galilei, Dialogue Concerning the Two Chief World Systems (1632)

Last weekend offered up the most spectacular weather imaginable, and we headed to East Beach, Galveston and Frenchtown Road, Bolivar. Arriving at low tide, our timing was perfect. Both these localities present exceptional naturalist experiences, especially at low tide. Where else is there evident a more elegant connection between the astrophysical, geological, and biological worlds than in an intertidal zone?

At East Beach we watched Greater and Lesser Yellowlegs hunt among the ripple marks, tidal channels, and pools abandoned by the retreating tides. Vast flocks of Black Skimmers whirled overhead and large numbers of gulls, terns, and American White Pelicans gathered on emergent sand bars.

Near Frenchtown Road, low tide means that oyster patch reefs are exposed, and Red-breasted Mergansers, cormorants, and waders fished in the tidal channels between the reefs. Shorebirds like American Avocets, Willets, and dowitchers hunted among the exposed clusters of oysters. Forster’s Terns were plucking small fish from the surface waters of the channels. I was surprised to observe the Willet below catching fish in the shallows between patch reefs—usually these birds are grabbing crabs from among the oysters.

Frustratingly, I realized that (being a landlubber from Minnesota) I do not know my Gulf Coast tidal zone fishes, so I could not identify any of the birds’ menu items. To remedy this situation, this week I ordered a copy of Fishes of the Gulf of Mexico: Texas, Louisiana, and Adjacent Waters by Hoese and Moore. It will sit next to my Peterson Field Guide to Freshwater Fishes of North America North of Mexico—so soon I’ll at least have a shot at identifying piscine prey, no matter the salinity.

Photographing Birds in Gloomy Weather

A cloudy day or a little sunshine have as great an influence on many constitutions as the most recent blessings or misfortunes.–Joseph Addison

I am sometimes surprised by which images turn out and which don’t. Light is magic, and photography is all about light. By magic I mean inexplicable—or at least very hard to explain in the context of how a camera records light. Case in point: we were recently attempting to photograph Sandhill Cranes in a field on Galveston Island. It was a clear, beautiful day, and I had a distant but unobstructed view of the birds. I wasn’t expecting National Geographic results because the cranes were too far away, but shot after shot was utter garbage.

The humidity was low (which was good), but it was windy (which was bad). I could tell that the UV index was high (I got a sunburn through sunscreen), and I just couldn’t achieve focus using autofocus or manual focus. I first tried bracing the lens on a fence post with image stabilization turned on, then off. When that failed, I returned to best practices: tripod with cable release. But still, everything farther than about ten yards away was blurry and washed out. Was invisible (to the unaided eye) turbulence creating some sort of mirage-like effect? I turned the camera on and off—even switched bodies thinking that there was a malfunction. Somehow, conditions simply weren’t right for photography—black magic. The next day I looked like W. C. Fields with windburn, sunburn, and a bar tan.

Other days, with fog or rain or lots of gray gloomy clouds, strangely, and against all odds, some nice images can be captured—white magic. I know that some photographers and viewers even prefer the look of results achieved during these dark, gloomy overcast days. All the images in this post were taken on a road trip to South Texas a few years ago. In fact, all were taken on the same day, except the kingfisher. And it was a winter like this one, with lots of rain and clouds and fog and mist and cursing by yours truly.

Of course, these dark days test your skills. To keep ISO below 800 for reasonable image quality means shooting at ridiculously slow shutter speeds (like 1/80 to 1/320) and breaking the 1/f shutter speed rule that I like to follow–even on a tripod with cable release. At these slow speeds, you’re in mirror-slap territory, especially on a tripod, and any puff of wind or contact with the gear can have deleterious effects. And patience is required to capture even the hint of a catchlight, an important aspect of wildlife photography.

Finally, because I pursue this hobby for personal growth and physical and mental health, seeing sunlight is so important. Like most Americans I suspect that I am Vitamin D deficient due to being cooped up so much at work. On these gray days, the spirits lift during an occasional sunbreak. The image of the Common Yellowthroat below was happily captured at the end of a gloomy, misty day just as the clouds parted (finally!) at dusk.

Bird Photography without Birds

Lately interesting bird sightings have been as rare as intelligent discourse during a presidential election or quality programing on network TV. The last few weeks of iffy weather and striking out on scouting expeditions to places we’ve never visited before (or perhaps only visited a time or two years ago) and seeing little in the way of birds got me thinking: Hey! I don’t need any birds to do bird photography! I can just take pictures of where birds have been! It also got me reminiscing about the all the other times out birding when we saw nothing!

Hope you didn’t need this tree for anything: Woodpecker-ravaged conifer tree, Apostle Islands National Lakeshore, Wisconsin. Theoretically eight species of woodpeckers inhabit this woods in summer, but we saw exactly zero. This woods seemed sparsely populated with birds in general. There were plenty of mosquitos, though!

Of course, other than abandoned nests and footprints in the mud (or droppings on a post), if you’re looking for signs of past avian activity you’re pretty much looking for woodpecker handiwork. Woodpeckers are among my all time favorite birds and have been chiseling holes in trees for at least the past 25 million years, since the late Oligocene Epoch. I used to think that petrified wood was a pretty mundane fossil until I started reading about ancient woodpecker holes—now I’ll be checking those hunks of fossil wood and hoping! Incidentally, there is lots of petrified wood around the Texas Gulf Coast, but being mostly Eocene (56-34 mya) it’s way too old for evidence of woodpecker activity, though. Pity.

Finally, while watching a Hairy Woodpecker chisel holes in the side of some guy’s house in Colorado last summer, I just had to admire the panache and devil-may-care attitude. Never mind that the hapless owner probably toiled thirty years to pay off the mortgage: let’s blast some holes! There may be tasty grubs inside those 2×4’s! Like City of Houston road crews, hammering away and leaving a lunar landscape behind, woodpeckers work their magic and are on their way!
