The Chigniks – Avian Diversity and Change in a Remote, Unique Environment

The village of Chignik Lake is situated approximately halfway down the Alaska Peninsula. The Bering Sea lies to the northwest, the Alaska Gulf to the southeast, and the Aleutian Islands to the west. The main draw for birders are seabirds, but in this ever-changing landscape, you never know what will show up. Yellow-billed Loons and Tufted Ducks are among uncommon species occasionally seen here and passerines that have strayed well beyond their normal range show up every year.

The Chigniks

By any standards, the three tiny villages that comprise The Chigniks are remote. None of these communities have more than a few miles of road, almost all of which is unpaved. Where the roads end, a vast wilderness begins. From Lake Clark, located at what might be thought of as the peninsula’s hip, all the way to the big toe of Cold Bay, the entire area is comprised of 32,922 square miles, a size just slightly larger than South Carolina. Yet it is inhabited by fewer than 2,000 full-time residents. Humans are significantly outnumbered by the region’s Brown Bears, the latter some of the world’s largest specimens. In any given season, the population of each of the Chignik’s three villages ranges from about 50 to 70 residents, a bit more during summers of strong salmon returns as commercial fishermen swell the ranks. But even within these sister villages, there is a hierarchy of remoteness.

The three Chigniks – Chignik, Chignik Lagoon and Chignik Lake are situated halfway down the Alaska Peninsula on the Alaska Gulf side. On the peninsula’s northern side is famed Bristol Bay where tens of millions of wild Sockeye salmon are commercially netted each summer, making it the world’s most productive wild salmon fishery. Black Lake is the headwater lake of the Chignik system. Twenty-five miles to the west of Chignik Lake is Mount Veniaminof, an active volcano.

The Chignik Drainage begins with the headwater streams flowing into Black Lake, a relatively shallow, weedy body of water vital both as a Sockeye Salmon nursery and for the waterfowl habitat it provides. While some of the smaller streams are fed by the water soaked tundra surrounding the lake, the larger ones, including Black Lake’s main source, The Alec River, originate in mountain glaciers. The area is geologically active, with Mount Veniaminof 25 miles to the west occasionally belching smoke and ash – activity that is occasionally audible at Chignik Lake. The upper Chignik River, sometimes referred to as Black River, drains Black Lake and flows for approximately 13 miles before emptying into Chignik Lake. From its outlet at the eastern end  of the Chignik Lake, the Chignik River flows roughly six miles east into the brackish estuary called Chignik Lagoon.

The most common way to reach Chignik Lake is by small plane; the local airstrip accommodates aircraft up to the size of a de Havilland Otter, a plane with a 10-seat capacity. The other way to reach the lake is to take a fishing boat or the ferry from Homer to Chignik (The Bay) and then transfer to a skiff for the run to Chignik Lagoon and up the Chignik River. (October 20, 2016)

The village of Chignik, often called Chignik Bay but locally referred to simply as The Bay, is an important commercial fishing hub. As a port of call on the Alaska Ferry system, it is the most cosmopolitan of the three communities. The village is home to a sport fishing lodge, a small general store and a boat harbor. Occasionally birders looking to add ocean species to their life lists and biologists conducting inventories visit The Bay. Thus the avian fauna in and near Chignik Bay is fairly well documented, though digging up an accurate checklist may prove challenging.

Tucked along a strip of beach and cradled by mountains, as a regular stop on the Ferry System Chignik Bay offers wildlife watchers an opportunity to check off a variety of seabirds and ducks as well as sea otters, seals, orcas, and whales. On shore, thick stands of alders and willow tangles provide cover and nesting sites for summer migrants including thrushes, warblers, and sparrows. Indian Creek, which flows through the village, can be a good place to watch spawning salmon and to perhaps get a look at American Dippers and Belted Kingfishers. (May 6, 2018)

This is the view approaching Chignik Lagoon from the sea, looking toward the Chignik River. Chignik Bay lies a few miles around a small cape to the east. (August 14, 2018)

Chignik Lagoon is sprinkled along the shores of the estuary into which the Chignik River debouches. The tidally influenced mix of fresh and salt water is nutrient rich and a variety of species gather here to feed including Harlequins and Long-Tailed Ducks, cormorants, scoters, puffins and Marbled Murrelets. This is an important wintering area for Emperor Geese as well as a vital staging area for Pink, Sockeye, Chum, Chinook and Coho salmon preparing to ascend the Chignik River. From The Lagoon, the village of Chignik Lake is about a six mile skiff ride up the river. Along the way it’s common to see Brown Bears, Red Foxes, an occasional moose, and, less frequently, wolves, lynx, river otters, mink and possibly wolverine. Whenever salmon are in the system, Bald Eagles are abundant.

Hugging the shores of Chignik Lake just above its outlet into the Chignik River, the village of Chignik Lake (center) is comprised of a few houses and buildings and a sum total of about three miles of dirt road running from a short dirt airstrip (highlighted light blue, center-right) and terminating at a small boat landing on the river just below the bottom edge of this photo. Note the weir spanning the river, lower right. This guides migrating salmon toward an opening on the right-side bank where Alaska Department of Fish and Game personnel count them. All five species of Pacific Salmon found in North America enter the Chignik: Sockeyes, Pinks, Chum, Coho and Chinook, the numbers for all but Pinks have been depressed in recent years. A few Steelhead – the anadromous form of Rainbow Trout – also enter the Chignik. Dolly Varden char are abundant. (August 14, 2018)

Several factors contribute toward making the Chigniks in general and Chignik Lake in particular of interest to birders.

  • Varied habitat: From the headwaters to the Alaska Gulf, environmental features include marsh, bogs, tundra, kettle ponds, mountains, alder and willow thickets, grasslands, lakes, rivers, feeder streams, a few mature spruce trees, an estuary and the ocean.
  • Abundant and varied sources of food
  • The Chignik Drainage serves as a migratory passageway complete with sheltered, food-rich fallout areas.
  • Because this area is comparatively lightly studied and because the topography and therefore habitat are changing relatively rapidly, the possibility of recording a species new to the area is ever present.

Chignik Lake, August 14, 2016: Note the skiffs beached along the lakeshore. As the river is the only highway connecting Chignik Lake with other villages, eighteen foot aluminum Lund V-hauls are the region’s equivalent of economy-class pickup trucks. The relatively massive buildings in the center are the school and associated housing for teachers. Not long ago, when Sockeye runs were strong, as many as 60 students filled the classrooms. In recent years against a backdrop of declining salmon runs and a depressed economy, student enrollment has hovered around a dozen. A drop below 10 would result in a lack of funding from the state and would necessitate the school closing – a hard blow to a community already holding on by its nails. (August 14, 2016)

For a variety of reasons, I decided to confine this three-year study to a three-mile radius encompassing the village of Chignik Lake. With the threat of the school closing ever imminent, and thus Barbra’s teaching position at The Lake annually in doubt, investing in the skiff that would have been necessary to explore the upper and lower reaches of the Chignik system wasn’t practical. And in fact the reason we departed Chignik Lake at the end of three years was due to student enrollment falling below the state-mandated minimum of 10 and the school board consequently reassigning Barbra to Newhalen School further up the peninsula.

That being said, it should be noted that the entire Chignik Drainage ecosystem, from the headwaters at Black Lake to the estuary, is rapidly changing.

  • Jungle-thick alder growth is taking over much of the landscape, crowding out salmonberry brakes, swallowing tundra, and marching ever higher up mountain shoulders.
  • Winters are becoming milder. This has meant more rain, less snowfall, lighter snowpack, and possibly (this has been difficult to document with certainty), greater fluctuations in river and lake levels.
  • The lakes and river remain ice free for longer periods of time. In some recent years, neither Chignik Lake nor Chignik River have completely frozen.
  • Black Lake is showing signs of eutrophication marked by gradual shallowing, accelerated weed growth and warming.   
  • The estuary is accumulating greater loads of volcanic ash and other silt. This is spurring the growth of eel grass and other vegetation. In turn, these grass beds capture silt, thus contributing to a process of salt marsh expansion.
  • Chignik Lake and the main river also appear to be growing siltier and weedier.
  • White Spruce and other non-native evergreens which were introduced shortly after Chignik Lake became a permanent settlement in the 1950’s are now mature, providing shelter, nesting habitat and food for a variety of bird species.

A Brown Bear with a fresh salmon follows a trail up a Chignik River bank leading into a tunnel of vegetation. Every elder I’ve spoken with in the Chigniks tells the same story: the water is weedier and the trees are thicker than in the past. (September 22, 2018)

While a paucity of quality photographs or other documentation makes it impossible to quantify changes in terrestrial vegetation, there seems to be little doubt that tundra is disappearing, that alders have become dominant, and that these changes are impacting bird populations. As an example, Narver made no observation of woodpeckers during his four summers studying the drainage back in the early 1960’s and elders maintain that they are a relatively new bird to the area. Though they still aren’t abundant, in recent years virtually every resident has noticed Downy Woodpeckers in and near the village.

Thick grasses overtake this old-time wood and sod home at Chignik Bay, an area that has been inhabited for approximately 2,200 years. Stone tools found at temporary sites further up the peninsula indicate that humans have been utilizing the Alaska Peninsula’s abundance of natural resources for at least 9,000 years. (Barabara at Chignik, 1909: Alaska State Library – Historical Collections, PO Box 110571, Juneau AK 99811-0571;

By contrast, Willow Ptarmigan, which Narver reported as “common” in the early ’60’s, are gone; no one saw or heard a sign of them during our three years at The Lake. While it could be that hunters have extirpated them locally, an equally likely explanation for their disappearance is that ptarmigan habitat has disappeared.

At the same time, undocumented observations and recollections can be notoriously inaccurate. Local residents misidentified Northern Shrikes as Camp Robbers (Canada Jays) and believed them to be a new species to the area. However, Narver noted shrikes in his study. During the three years of this study, they were common. It is possible that this species is intermittently present.

When the lupine bloom, the bumblebees get busy. Bombus ternarius, I think – an Orange-striped or Tri-colored Bumblebee. As is true of The Chignik’s birds and vegetation, local insect life, too, is no doubt changing. (June 19, 2019)

The wisest course regarding anecdotal accounts is to seek corroboration. However, that can often be challenging. In old photographs the landscape is generally a background blur, defying attempts to determine whether one is looking at alders, salmonberries or other vegetation. When did the lake freeze solid, on average, back in the 1960’s? Were the lake and the river always as turbid by late summer as they now are? What year were the first White Spruce trees planted? At one time, the story goes, there was a resident who knew how to catch the Chignik’s “Rainbow Trout” (most likely Steelhead), but he’s gone and the specific answers to such questions as when, where and how to go after these fish are gone with him. Among the little yellow and green birds that visit the area each summer, are there ever any Arctic Warblers in the mix? Is the absence of Ospreys due to the lack of a suitable nesting site, or are other factors at play?

These and many other questions remain open to inquiry by anyone with the curiosity and time to venture out into the Chigniks and explore. Each discovery and observation is a puzzle piece to be fitted into a larger picture in this fertile, dynamic, and rapidly changing ecosystem.

Vacancies at Chignik Lake’s New Nesting Boxes are Filling Fast: Tree Swallows have Arrived!

We knew that with Violet-greens having returned, Tree Swallows wouldn’t be far behind. This pair didn’t let much daylight burn before checking out a homesite. They may have used this same box last year. That’s the female perched on top of the box while the male, decked out in shimmering shades of blue, assesses the nesting quarters.

Just before leaving The Lake for our epic 65-day bicycle tour of Hokkaido last spring, we installed four new nesting boxes. We left just as the swallows were returning, but when we got back we were informed that our boxes had immediately attracted new tenants. So we’ve been keeping our eye on them, eager for the arrival of Violet-green and Tree Swallows this spring to see who might move in. Violet-greens first showed up on May 14 and headed straight for a set of older boxes at a neighbors’ house. But even with some 40 boxes in the village, we knew every available site would soon have a pair of nesting birds.

This morning when I stepped outside, I lifted my binoculars to scope out silhouettes on a power line near two of our boxes. Tree Swallows – the season’s first! With the early morning sun buried behind gray clouds, there wasn’t much light. But the office where I work on photos and writing has a view of one of our boxes, so I kept my eye on things. Within a couple of hours, new arrivals were checking out the two boxes closest to our home. And then the sun popped out, giving me an opportunity to make a couple of pictures of birds beginning to set up housekeeping at each box.

For awhile, several birds sallied back and forth around this box. Finally a female entered and stayed put for quite awhile. Here the male is checking up on her.

Sandhill Cranes Foraging and Vocalizing – Alaska Peninsula

Barbra’s school year ended on May 1st. With a new home waiting for us in Newhalen, Alaska, we could have left Chignik Lake the following day. But bears are waking, buds are bursting and springtime’s migrant birds have begun to return, so we’ll remain at The Lake till late June. We’ve been loving our decision. In the past few days we’ve scored photo upgrades of several Chignik species including Northern Pintails, American Widgeons and Harlequins. We just missed adding photos of a skittish dark morph Rough-legged Hawk as well, but we got nice American Robin photos (the ones that pass through the Chigniks are considerably more wary than the suburban birds we’ve known) and…

…our first really good photos of Chignik’s Sandhill Cranes.

The more we photograph birds, the more we appreciate how difficult it can be to predict their behavior. Years ago, we had a photo op with a pair of Sandhill Cranes foraging on a lawn in Homer. While Barbra crept around the yard with our “fledgling” camera gear snapping photos, the cranes very casually walked off a few paces to let her know when she got too close. After that, Barbra tucked in and shot away. We left before the birds did. We weren’t birders in those days. The encounter was one of our first with cranes, and so we concluded that cranes must not be particularly wary.

Years later and multiple mind’s eye images of Sandhills that saw us long before we saw them gliding off toward the horizon on six or seven foot wingspans have prompted revisions of our earlier ideas about these magnificent birds. Cranes are hunted, and like most species that are hunted, they can be exceedingly wary. Unless the cranes have located themselves in a refuge of some sort, it seems that your best chance of getting close enough for a decent look at them is to a) stay quiet and b) don’t look like a human.

The other day while birding, we lucked out. Using a truck as a blind, we were able to observe a pair of foraging cranes for about 15 minutes – plenty of time to add quality photographs to our library and to make a short video which, happily, caught them vocalizing. The male in this video stands over four feet tall. From now till September, their brassy, ratchety calls will echo through the Chigniks, carrying as much as two-and-a-half miles. In addition to the full-throated vocalizations, listen for the little croak the male gives early in the video. And incidentally, the songbird in the background is one of our recently-returned Sooty Fox Sparrows. (The chirping is the modified sound of Jack’s camera shutter.)
