When I initially got into studying the Chignik Drainage’s birds, I thought that a loon was a loon was a loon, a species I knew primarily from seeing Common Loons. I assumed that that is what a loon is. It turns out that there are five species of Gavia, four of which occur in the Chignik Drainage. In order of common occurrence, they are: Common Loon, Pacific Loon, Yellow-billed Loon and Red-throated Loon. (Only the rare Arctic Loon is absent from The Chignik.) It is probable that in the salt waters of the nearby Alaskan Gulf that from fall through spring it is the Pacific Loon that is most common.

We encountered Yellow-billeds as wintertime visitors to the main lake and the river outflow just below the lake. In wintertime, their plumage is rather drab (you’ve got to go to the most northern parts of Alaska, or Siberia, to see them in their stunning breeding colors); however, even in winter these, the largest of the five loons, were easily distinguished from Common Loons by their big, lightly-colored, yellow-tinged bills. We found the Yellow-billeds to be shy and to prefer deep water. The only photos I was able to get were taken using a 600mm lens affixed with a 2.0 teleconverter of far off specimens – and even those images require significant cropping to present a picture such as the one above. Still, Yellow-billeds are uncommon to rare and adding them to the Chignik Drainage List – perhaps a first documentation and almost certainly a first photograph – was a thrill.

Any documentation of this sort is important. As the planet continues to rapidly warm – due largely to a certain overpopulated species’ reliance on burning fossil fuels and turning forests to farmland – things are changing. Fast. (It’s not just that the climate is warming – it’s been doing so for a very long time. It’s the recent rapidity at which it is warming.) Audubon’s climate model projects a 64% loss of winter range for Yellow-billed Loons in coming decades. Not centuries. Decades.

Wherever you live, it is likely that you can see changes in flora and fauna over time. And these changes are not due only do warming. Although in pure numbers countable trees have increased in many areas, most of this new growth is in the form of pulp and timber forests – trees destined to be cut down just as they are reaching maturity. As fewer forests are allowed to reach and sustain maturity, there is less mast (acorns, other nuts, seeds and seed-bearing cones) for animals to forage and often fewer nesting sites as well. Wild grasslands have nearly disappeared from our landscapes. In many locales, streams, rivers and lakes have become warmer, shallower and increasingly over-nutrified owing to run-off from fertilized lawns and farms. So grab a pair of binoculars, a notebook, your iPhone or camera and get out and observe. The regular outings might prove to be a great education, and a daily walk is invigorating.
