Ermine (Short-tailed Weasel) Chignik Lake, Alaska Peninsula, August 2018
A Collared Lemming burst from a thicket of grass and swam across a narrow finger in the lake which was filled to the brim with recent rains. Just as the little rodent disappeared in a patch of thick grass on the opposite side of the water, an Ermine popped out from where the lemming had just come, paused, looked around, appeared to sniff the air, then also swam the same course. I was scrambling with my camera hoping to capture something of the surprise sighting and managed to capture the above image just before the Ermine dove into the grass.
We didn’t often encounter either of these species during our years at The Lake, but there was hardly a walk after a fresh snowfall that we didn’t come across small paired tracks left by Ermines bounding through snow, so they appeared to be fairly abundant. Cool animals. I would love to have made friends with one the way Sam made friends with Baron in My Side of the Mountain… The closest I came was when one ran across the toe of my boot and into the entrance of our house as I opened the door one morning.
Blakiston’s Fish Owl Shiretoko Peninsula, Hokkaido, Japan, July 23, 2018
With a wingspan ranging from about 5′ 10″ to 6′ 3″ (170 – 190 cm), Blakiston’s Fish Owls are generally regarded as the world’s largest living species of owl. The photograph above is of one of a known wild pair which have been banded. The owls regularly visit a small stream where a pool has been created with natural rocks and is regularly stocked with Cherry Trout (sakuramasu, O. masau). A small inn with windows overlooking the pool provides guests with opportunities for a glimpse of this rare species which may visit the pool at any time during the night. The indigenous people of Hokkaido, the Ainu, regarded these great owls as spiritual protectors of their villages.
For context, Barbra with this taxidermy specimen grasping a White-spotted Char (Rain Char). Blakiston’s Fish Owl is a type of Eagle Owl and therefore related to the familiar Great Horned Owl of North America. The Great Horned Owl has a wingspan of approximately four feet, two feet less than the Blakiston’s span of around six feet.
Female Transient Orca with Seal against Aleutian Mountain Landscape Training Day
I wasn’t sure what to call this photograph, so I’ve gone with straight description. The Alaska Peninsula’s Aleutian Mountains again provide a dramatic backdrop and (I think) stunning context for this photo of a female Transient Orca and her prey, a thoroughly defeated seal. Looking closely, you can see the seal’s facial whiskers near the Orca’s nose, his body further to the right. She’s lost a bit of skin from her snout, no doubt from raiding the rocky shoreline for catches such as the one she is now contemplating.
While the female Orca was using this living prey to teach her daughters hunting techniques, the male (see the previous two articles) was checking out our skiff.
Throughout our time with this group of Orcas the light was all over the place as clouds closed and opened above. Many images from this shoot came out flat, like blue-tinted monochromes. But a few, such as this one, are nicely lit as the sun just began to emerge from behind clouds.
Killers: Father and Daughter, Training Day Chignik Bay, Gulf of Alaska, May 6, 2018
The above photograph is of an adult male and a young female Orca. Killer Whales in the vernacular. Actually, not true whales, but the world’s largest dolphins. They were part of a family of four which also included an adult female and a much younger calf, perhaps also a female. I had been invited along on a crabbing and halibut fishing excursion by my friend Fred Shangin. We were headed to Castle Bay, which meant skiffing from the village of Chignik Lake six miles down the Chignik River, then six miles through Chignik Lagoon, out around Dark Head and then 10 miles down the Alaska Peninsula to Castle Bay. In the above photo, the Orcas are about three miles offshore not far from the seaside village of Chignik. See the Google Maps below:
Anchorage is in the upper right. The red star halfway down the Alaska Peninsula indicates the general area of Chignik and the site of the Training Day photograph above.The purple line indicates the navigational course Fred took us on that day.
These are Transient Orcas, members of the Gulf of Alaska, Aleutian Islands, and Bering Sea (GOA/AI/BS) population.1 As Transients, their primary source of food is marine mammals. When we encountered this family, Fred idled the skiff engine and for the next half hour we watched the parents teach their daughters about hunting seals. First, with the daughters following closely, the adults cruised in tight to the rocky shoreline where they corralled and caught a seal. Rather than kill it, the female gently took the hapless pinniped in her mouth. Barely holding it by her front teeth, she swam out into open water where the adults continued to teach the youngsters lessons they would need to survive.
Training Day, Fred called it.
I was still pretty new to photography and had never shot anything like the scene that unfolded. Lots of mistakes. Several times the male, which was enormous, swam right beneath our little skiff and then emerged, impossibly close, to check us out. At other times the female and even the older of the two daughters came in close, again looking us over. I managed to make a mess of what would have been incredible closeups of these great beings. In fact, the entire family, very much aware of us, seemed at times to be showing off as they taught and learned their own unique art of hunting. However, despite my excitement and fumbling I managed to get a number of interesting pictures, a few of which are difficult to look at if one has any empathy for the little seal.
Once the first seal was finally dispatched (the female performed the messy coupe de grace), the male caught a larger seal for himself. I’ll probably publish additional photos of this remarkable, seldom-witnessed event in the coming days.

Juvenile Black-billed Magpie The small pink patch at the base of this bird’s bill marks it as a youngster. This area on a mature bird is dark. Chignik Lake, Alaska January 2018
Among most humans (and perhaps among most of their fellow birds as well), magpies historically have had a low reputation. They rob nests and nesting boxes; their raucous calls grate; they bully other birds out of feeders; they assemble in packs, chattering in the manner of hoodlums planning their next escapade; and although their omnivorous feeding habits are generally focused on berries, seeds and scavenging (they love a good salmon carcass), a telltale hook at the end of their bill which grows more pronounced with age should be warning enough to small creatures that it is wise to give magpies a wide berth.
But I like magpies. In fact, I think I’ve grown to love and admire them – and not just cynically because they supply a steady source of prey to the Great Horned Owls at the Spruce Grove. (At times it’s a veritable boneyard of magpie skulls, femurs, bills and feathers beneath the owl roosts there). To establish a relationship with these intelligent beings, it is first necessary to ensure that they cannot prey on the eggs and young of passerines utilizing nesting boxes. To that end: 1. Make certain that nesting box entrance holes are no larger than what is recommended for the target species. 2. Never place a perching peg on the box. Nesters do not need such a perch, but predators will use it to get at eggs and young. 3. Take appropriate measures to limit these comparatively large birds from accessing feeders. (Suggestions can be found with a google search.)
Were one on vacation in, say, a tropical locale never having seen a magpie in the wild and an adult in elegant, iridescent breeding colors happened by it is likely the bird would be greeted with oohs and ahhs for its stunning beauty. In a future post or two, I’ll publish such photos of Chignik Lake magpies with summer sunshine lighting their regal emerald greens, glowing turquoise and royal purples. And if you listen, really listen, to magpies, you’ll soon begin to appreciate that there is a lot more going on in their language than harsh cries. It can be fascinating to watch a conventicle (the preferred collective descriptor for this species) gathered together, pacing about the ground, their soft utterances back and forth sounding very much like a secret language. And then, of a sudden, one takes flight. The others follow. To where and to what mischief or adventure? There is surely more on the minds of magpies than mere food, shelter and reproduction.
Magpies are one of the few nonhuman species able to recognize itself in a mirror. They can solve fairly complex puzzles – both under lab conditions and in life. They are remarkably attentive parents (even breaking up food into equal portions to ensure that all of their young are properly fed). They mourn their fallen fellows, attend to injured brethren and give all evidence of being able to distinguish among – to recognize – individual humans. Thus, they can be befriended – and no need to take away their freedom and make of them a “pet” to do so. Recently fledged magpies are typically curious and congenial. Show them respect and kindness. It may be surprising to discover what kind of relationship develops.
Yellow-billed Loon – Chignik Lake, Alaska, 11/27/17
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.
Young Master Speck Among all Alaska’s wildlife, is there any like our Foxes for hitting the precise nexus of beautiful, handsome and cute…Chignik Lake, April 1, 2017
Male Red Crossbillforaging on Sitka Spruce Cones, Chignik Lake, Alaska. These birds can only live where forests are allowed to mature and produce healthy cones. Forest management that focuses only on replanting trees destined to be turned into pulp before they mature provide little to no benefit to most species.
Anyone who has much studied biology in general, birds in particular, or evolution specifically has undoubtedly encountered “Darwin’s Finches” and the remarkable diversity in bill shape that evolved among a species related to tanagers (not true finches) that became geologically isolated on the Galapagos Islands. Darwin visited the islands, which straddle the equator approximately 560 miles west of Ecuador, in 1835. There he collected (his servant shot) an array of birds featuring 18 different bill shapes. The variation correlated with the different foods each type of food the birds had adapted to take advantage of on the islands. As all of the species Darwin identified originated from a single type in genus Geospiza, Darwin’s Galapagos finches have long been held up as an example of how evolution works. It’s a complex process that occurs over time and I don’t want to oversimplify it. However, for the purpose in this article, it is useful to think of 1) an underutilized food source and 2) genetic isolation. The original tanager-like specimens of a single type in genus Geospiza became isolated on the Galapagos islands. Given an absence of competition from other species of birds and an abundance of various foods – insects & invertebrates, berries, seeds of different size -, various forms of the original type of Geospiza evolved different bill shapes and sizes (and even different body types) as they keyed in on a given kind of food.
Somehow, I think, (speculate), vocalizations must have played a key role in the genetic isolation that concurred with the move toward food specialization among these Galapagos finches. Most species of birds have a variety of calls and songs, each of which conveys a specific meaning. Black-capped Chickadees, for example, communicate with at least 15 different sounds (let us think of them as words) differentiating everything from the approach of different kinds of predators (one vocalization for ground predators, another for aerial predators) to vocalizations used during breeding, to identify food sources, and so forth.
Bird vocalizations play an important role in differentiating similar species. For example, although certain thrushes to the untrained eye appear quite similar, their songs are different enough to easily distinguish. Similarly, the Pacific Wren found in west coast states from California to Alaska is nearly identical in appearance to the Winter Wren which is found in the east and midwest. But the songs of the two species are different. Thus, they are genetically isolated from each other as much by their vocalizations as by geography. After all, they have wings. They are thus able to transcend geographical boundaries. Their songs – agreeable to members of their own tribe, a foreign language to others – helps keep the two populations separate.
Apparently a good bit of the above applies to Red Crossbills. I have photographs of Red Crossbills from Montana that show a recognizable difference from the Red Crossbills we encountered at Chignik Lake. The Montana birds have larger bills. What causes the difference? Probably diet. The Montana birds we saw were feeding on the seeds of Ponderosa Pine cones. My guess is that it takes a more substantial bill to get into the harder, tighter pine cones than it takes to pry apart the looser scales of the softer Sitka Spruce cones found at Chignik Lake and other locales in Alaska.
So, just as ichthyologists have come to understand the significant genetic variation that can exist among a given species of fish – such as Steelhead or Coho Salmon – as each kind of Steelhead or Coho has adapted to thrive in a given river system – ornithologists are coming to understand that there can be a great deal of intra-species variation among birds as each type within the species has evolved features allowing it to thrive in a specific habitat.
To me, the take-away lesson here is that we should not merely be focusing on the preservation of life forms on the species level, but that instead we should be dedicated to the preservation of each unique biome and ecosystem.
A second bear is just barely visible in the upper left of this photograph of a healthy sow that has trapped a spawning Sockeye Salmon in her forepaws beneath the water. Anytime the salmon are running from July through November, bears can be expected along the river and lake.
Loafin’ Sometimes Sea Otters hanging around in harbors become quite accustomed to humans. For this photograph, I got down on my belly and lowered my arms and camera over the side of a dock. Unable to look into the view finder, I let the camera’s autofocus do its job. They’re awfully cute. Seward Harbor, Alaska, 6/25/13
