Where there are salmon... EAGLES WILL FOLLOW
“I don’t remember there being a lot of
fuss over eagles back then,” said Valle, a 1962 Burlington-Edison High
School graduate.
In the 1960s, bald eagle numbers in the continental United States had dropped
Nowadays, people fuss over the eagles. Each Wednesday during the winters, three spotters count the snowy-headed raptors along the 150 river miles between Sedro-Woolley and Newhalem.
Eagles also draw tourists to Eastern Skagit County. Last weekend, 700 people stopped at the Skagit River Bald Eagle Interpretive Center in Rockport, said Ember LaBounty, a volunteer at the center.
Almost always, the number of eagles
peaks in mid-December, LaBounty said. The peak coincides with the chum
salmon run.
There’s a direct correlation between the numbers of returning chum and eagles that flock to the Skagit River, said Brett Barkdull, a district biologist for the Washington Department of Fish and Wildlife.
“The eagles go where the food is,” Barkdull said. “When there is lots of food on the upper Skagit, they go there.”
This year, the number of returning chum has been down and as a result, the number of eagles counted on the Skagit is lower than it has been in recent years.
So far this season, the eagle count
peaked Dec. 23, when 300 of the raptors were counted. Since then, the counts
have hovered around 100.
LaBounty said there’s no way to predict what the eagles will do, but generally they number around 100 until the end of January or the first week of February.
Final data is still being compiled on
the number of chum that returned to the Skagit. But fish biologists already
know the picture is dismal.
Initially, state scientists forecasted
25,000 chum would return. Later, they revised that prediction to 17,000.
Even the higher number is well below the state’s goal of
“The numbers are way down,” B a r k d u l l s a i d Thursday. “If I had to guess it’s probably closer to 20,000.”
For comparison, 19,400 chum returned to
the Skagit in 2007. In 2005, there were 34,000 chum.
For reasons that fish biologists haven’t determined, chum numbers are lower in odd years, higher in even years. In even years, the state’s goal is 116,500.
Reduced chum runs were noted in rivers throughout the Puget Sound region, Barkdull said.
State biologists think the ocean
“For whatever reason, in Puget Sound,
ocean survival for chums is down,” Barkdull said. “It’s way
Other salmon species didn’t suffer the same fate as the chum this year. Puget Sound pink and coho salmon, as well as Columbia River sockeye, had “fantastic” runs, Barkdull said.
Roughly 2 million
“We had so many fish — it was
ridiculous,” he said.
The coho survival rates were about 20 percent, Barkdull said.
“We haven’t seen this high a survival rate since the late 1980s,” Barkdull said.
Even when chum have a good year, other factors — such as river level, winter flooding and the concentration or distribution of dead chum — affect where people can find eagles.
“You just can’t predict it,” LaBounty said.
Recent rains have raised the Skagit River enough to cover the gravel bars and banks where the dead chum generally wash up and eagles dine.
“The river is very swollen this year,” LaBounty said.
Still, there are eagles to be seen on the upper Skagit, as well as on Camano Island and Padilla Bay, she said. At his home near Port Susan, Barkdull said he’s seen eagles going after ducks.
One year, the chum run came early on the
Sauk River, a tributary of the Skagit, and 400 to 500 eagles
“In 2002, when we had big chum (runs) all over Puget Sound, the eagles were scattered all over the countryside,” he said.
