Thousands of eagles flock to Harrison Mills for the world's largest congregation


HARRISON MILLS, B.C. – Thousands of eagles along the Harrison River in British Columbia are gathering for salmon reaching the spawning area.

David Hancock, a biologist who has studied eagles for about 65 years, says the world's largest bald eagle community takes place in a small community in Harrison Mills, located about 100 kilometers east of Vancouver.

"I did a survey on the river last Saturday morning and there were more than 7000 eagles in the area," he said in a recent interview.

”This is the biggest thing we've had in November.“

Hancock said about 35,000 eagles had been gathered in the Fraser Valley between November and February, and some 2,000 to 3,000 raptors were moving on some days.

Verimli This is the largest single spool area because the Harrison River is the most efficient river alone, H said Hancock.

39 The only river in Canada called the salmon river. “

The Harrison River is a branch of the Fraser River, approximately 18 kilometers long.

The rivers in Yukon, the ice-cold food supplies of Alaska and North British Columbia freeze, pushing the eagles southward.

In the depths of the Harrison River in British Columbia and where the mountains are standing, thousands of eagles begin to look like salmon. Bald eagle, Harrison Mills, B.C., eats a chinook salmon along the Harrison River on Thursday, November 24, 2016.

Land Our salmon just started to die, so the table was set here, H Hancock said.

However, there are other factors contributing to the number of eagles descending into the region.

Edi Sometimes the north doesn't freeze and the eagles don't have to come, “he added.

”In some years we don't get too much salmon, so the table wasn't generously adjusted.“

Crows are staying in the area until February, but several thousand people can fly further towards Washington, Oregon and California in the winter.

Hancock said this year that the Harrison River isn't enough salmon.

”This was not a good year for spawning,“ he said.

When the salmon carcasses gone, the eagles were fed with the smell of herring and oolachin.

In about four years, this area may not see too many eagles, because over-harvesting means there will not be too many salmon carcasses to feed.

For the past two decades, Hancock said researchers have learned about the connection between the huge trees and the salmon in the forests of the area.

The carcasses of the laying salmon give nutrients to the soil and help grow the trees.

Lar It doesn't have big forests without salmon, ock Hancock said.

”This is the lesson we learned in the last 20 years of ecology.“
