When David Hancock saw the bald-eagle count on the Chehalis River drop from more than 7,000 to fewer than 400 over a few days in December, he knew a crisis was coming.
Earlier this week, news reports that starving eagles were "falling out of the sky" in the Comox Valley, on Vancouver Island, confirmed his fears.
Wildlife rescue centres on the Island have reported birds growing so weak from hunger that they fall out of trees, or fly so clumsily they hit things. One crashed into a roof.
Mr. Hancock said a collapse of chum salmon runs has left British Columbia's bald-eagle population without enough food to make it through the winter, leaving them weak from hunger and forcing thousands of birds to scavenge at garbage dumps.
Reports of starving eagles have been coming in from all over the Lower Mainland but seem concentrated in the Comox Valley, he said.
"This is what I said would be happening," said Mr. Hancock, a biologist, publisher and author of
The Bald Eagle of Alaska, BC and Washington.
