Busy Days For The River Patrol

The bald eagles and smaller eagles also along with other scavengers like the buzzards and coyotes are busy with river patrol while salmon spawning season is in full swing. Slower running water in shallow pools become nests and breeding grounds for groups of the fish. Watching the water a person may only see the backs tipping out of the water as it looks like it is boiling with the 50 or more salmon in a nesting area laying eggs and dropping sperm.

A spawned salmon that had been pulled from river lays on the bank.At about 24 inches long, this salmon had been plucked from a group of fish in the shallows by one of the bald eagles and was laying along the water line near the bridge.

Judging from the color, this was a new arrival  showing some of the bright red tinge that they get when moving from the salt water ocean to the fresh water rivers. This salmon was still pretty beat up by the trek to the spawning ground and losing half of his face while being plucked out of the river by the eagle sealed the deal.

As the multitudes of fish spawn out, the colors will darken as will their ability to stay alive. Within a couple of days the fish will be black except for the areas where their flesh sloughs off in chunks. The mighty salmon fight to the end.

The river keepers pick up patrols and scour the rivers edge as the fish perish, the bounty will only last a few days.

State Of The River

It was only a few weeks ago when I was posting pictures of the beautiful fall leaves and the quiet Nehalem River. After the week of rain we just experienced, most of the color has washed out of any of the remaining leaves and the river is running the full span of the bridge.

The river is running high after a full week of rain.I know the ocean-going salmon are there spawning because the bald eagles are keeping a close eye on the river. While the river is high like this, they can only sit in the tall fir trees and wait when they are not flying the route of the river.

As the water begins to recede and the muddiness of the water clears, the eagles will once again have a chance to snag the carcasses of the spawned-out salmon. The eggs will have already been fertilized and the eagles are happy to scoop up the dead salmon keeping the water clean and healthy.

 

Two Birds With One Tree

Two bald eagles in the top of a dead fir tree.The two bald eagles have been guarding the river closely these days.

They can be seen swooping low to watch the water then soar high above the hillside in an air-dance frolic with each other. Occasionally they will sit for hours while they wait for a rain shower to clear, or for their wings to dry before taking off on another hunting jaunt.

These two adults have been a part of the area for several years now and prefer to hunt and rest together. We do not know if they are a couple or what sex they are. Sam showed up first, it just seemed patriotic to name him after ‘Uncle Sam.’ A couple of years later, ‘Yul’ showed up to complete the name, Sam and Yul…Samuel.

The sounds they make remind me of squeaky cupboard doors as they call from one tree to the next. Even when they sit close to each other, the squeaks continue.

Once aloft the familiar cry, the high-pitched iconic squeal, pierces the air as they protect their hunting route.

These birds monitor the river in anticipation of salmon as they complete their life-cycle of returning to fresh water after spending a year or two out in the open sea. The salmon make a harrowing journey back up into fresh water to their own spawning area in order to procreate only to perish in the water from which they originally were hatched. The change from fresh water to salt water was an easy transition for the fish, the change back from salt water to fresh water is impossible for the salmon and they die within a couple of weeks of entering the river. Carcasses of the fish float to the sides of the river after spawning, where the eagles pick the bones clean in short order.

 

Ups and Downs

The Nehalem river in the autumn.After the wild weather we had last week the river has once again settled and is much more clear and smooth running.

Just a week ago, the river was so muddy that we could not see if the salmon were coming upstream yet this year.

The bald eagles have been letting us know the answer, they have been guarding the river diligently, so we know that the fish are there. Even during the rainy days, the eagles were seen hanging out in the trees above the river trying to dry their wings.

 

 

Reverse Fishing

The warmer spring weather has been drying up the small streams and ditches that only run during the wet winters.

The ditch along the blackberry patch that Mike cleaned out with the bulldozer last year is still running, but the water level in the river has dropped enough to cut off direct access for the salmon parrs (baby salmon that have just grown out of their ‘fry’ size and  before ‘smolt’ size when they head to the ocean). About 20 of these one to two inch cuties were land-locked and needed a little help to get to the river.

Land-locked salmon parrs in a small ditch needing to be moved to the river.I had the pleasure of spending a beautiful afternoon dipping and scooping the little fish first into a cup then into a bucket before finding a shallow eddy where they were released back into the Nehalem. They are amazingly agile and can zip back and forth through the puddles quicker than I can focus, which is why it took me several hours.

I was able to get all the little creatures I could find moved to the river, but I will keep an eye on the ditch for the next couple of days to see if I missed any. Hopefully,  the little swimmers will grow and  continue into adulthood in the open ocean, it will be a long wait because they won’t be making that journey until they are about 4 years old.

 

View From the Bridge

As I was walking the bridge over the river to feed the cows one morning, I heard some rustling in the water below. I was hoping to catch a glimpse of an ocean-going salmon returning to spawn.

I focused the camera toward the noise and saw several shapes. The movement was about mid-picture toward the left bank. The salmon usually stay in the deeper channel as they work their way upstream.

Zooming in with the camera let me see just what the noise was all about.

Several pair of mallards had decided to take a winter river cruise. With all the flapping and splashing about, it sounded like they were having a pretty good time.
