Waiting for Salmon

Infinite Patience – Bald Eagle scanning for salmon, Chignik Lake, May 20, 2019

Each year from June 1 when Alaska Department of Fish and Game biologists begin counting at the weir on Chignik River till late summer when they remove it, an average of over 700,000 Reds (Sockeye Salmon) are tallied making their annual spawning run up this watershed on the remote Alaska Peninsula. In 2015, the number was a staggering 1,123,898 and that’s after a million Reds were taken by commercial fisherman in Chignik Lagoon, the saltwater estuary the river debouches into. Because Alaska persists in the foolishness of allowing “intercept” fisheries further out at sea, it can be difficult to determine precisely how many salmon are headed for the Chignik watershed – perhaps two million on average. Nonetheless, over that past nine years an average of 780,000 Sockeye Salmon have been counted at the weir.

Last year that number plummeted to just 540,000, and that was despite a nearly complete closure of the commercial fishery. It was, quite literally, a disaster. The cases of beef stew, generic peanut butter, lentils, canned fruit cocktail and boxed mac and cheese freighted in by government agencies didn’t begin to offset the economic and psychological hole the Sockeye collapse created.

As I write this, eager neighbors are already setting nets. Here and there an early-returning fish is showing up. But “early” is the operative term. Even in good years, the run doesn’t get going until the first week of June. Sometime during the second week of that month, the first counts of 1,000 fish a day might begin. Later in summer, daily counts will top ten thousand. The Chignik’s feeder streams will be carpeted with spawning fish. Brown Bears and Bald Eagles will be everywhere.

In a good year.

For now it’s still early.

Everyone is waiting…

…and hoping.

They enter the river with muscles of steel, bright as new dimes. By the time they’re ready to spawn, they will fill clear tributaries in a carpet of crimson. They are the lifeblood of the Chigniks. Reds…

 

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.

Establishing nesting boxes is way more interesting (and way, way more ethical) than plugging in those nasty electric bug zappers. Click the links below!

New Homes Available! Swallow Nesting Boxes at Chignik Lake

Our Violet-greens are Back at The Lake!

A single Violet-green Swallow can consume hundreds of mosquitoes and midges a day. With 40 or so nesting box cavities scattered throughout the village of Chignik Lake (population 50), these iridescently-plumaged little fellows and their Tree Swallow cousins are local favorites.

Chignik Lake’s first swallows, multi-hued Violet-greens, made their seasonal debut yesterday, May 15. This morning we went out to get photos of these much anticipated first arrivals. Tree Swallows, which will also use the dozens of nesting boxes residents have put up, should be arriving any time now along with the Bank Swallows that have established a colony on a bluff a mile or so down the Chignik River.

The Native American tradition of hanging nesting cavities for swallows goes as far back as anyone knows. Writing in the 1800’s, John J. Audubon noted that:

The… Indian is also fond of the Martin’s company. He frequently hangs up a calabash on some twig near his camp, and in this cradle the bird keeps watch, and sallies forth to drive off the Vulture that might otherwise commit depredations on the deer-skins or pieces of venison exposed to the air to be dried. The slaves in the Southern States take more pains to accommodate this favourite bird. The calabash is neatly scooped out, and attached to the flexible top of a cane, brought from the swamp, where that plant usually grows, and placed close to their huts. Almost every country tavern has a Martin box on the upper part of its sign-board; and I have observed that the handsomer the box, the better does the inn generally prove to be. 

It’s sad to see those annoying, energy-wasting, indiscriminate electric bug zappers, which kill beautiful moths along with everything else, hung more often than nesting boxes in these modern times. A nesting pair of birds will do a better job keeping pests under control, add cheer to any property, and when the wooden box has seen its best days it can be be left to return to soil rather than discarded to fill our world with yet more plastic, toxic parts and slowly-decomposing metal.

If nesting boxes around our village are any indication, they need not be elaborate. All that’s needed is untreated wood, a saw, a means to cut a hole, nails or screws and the appropriate tool for securing that hardware. Although it is often recommended that boxes be cleaned out annually, we know of no one here who does so. The swallows themselves seem perfectly capable of spring cleaning when they arrive, as they have done with natural cavities for as long as swallows have been around. However, if you’d feel better about cleaning out the boxes once the nesting season is finished, by all means go for it; you’ll be creating a clean space for birds that use the boxes as overnight and foul weather shelters during wintertime.

Engaged in housekeeping (removing his offsprings’ excrement) this Violet-green and his mate made a nest behind a knothole in the side of a store in McCarthy, Alaska.  

Two additional tips for your own backyard nesting boxes:

  1. Do Not put any sort of ledge or peg in front of the hole. As you can see in the photo below, swallows and other cavity nesters don’t need a perch. Their claws are adapted to cling to the sides of trees. The only purpose a ledge or peg serves is to give nest-raiders such as magpies, crows and other predators a perch from which to get at eggs and nestlings.
  2. Give some thought to the species of bird you hope to attract, then research the size of entry hole and the size of the interior cavity that bird prefers.

To those tips, we’ll add a third. Invasive European Starlings and House Sparrows haven’t yet found us out here on the Alaska Peninsula. If they are a problem where you live, we urge that they be discouraged from nesting by any means necessary. Both of these birds represent a significant, growing threat to species diversity.

Don’t have the time or the right tools to build your own boxes? Consider purchasing. A cedar box will last a long time, making it an economical gift to birds for years or even decades to come. And don’t be discouraged if your boxes don’t attract guests right away. Sometimes it takes more than one season for birds to move in.

Flowers are blooming, insects are out, swallows are returning and salmon are beginning to stage in the bay for their annual spawning run up the Chignik River. It still feels like spring, but summer is just around the corner.
