Eggs in eagle-cam nests mean newborn chicks will be in view soon

It's not a fast-moving show and has only intermittent episodes of sex and violence, but it's one of the few produced-in-B.C shows that brings in viewers from all over the world.

The eagle cams are up and running in five eagle nests, including Sidney, and, to the excitement of Dave Hancock of the not-for-profit Hancock Wildlife Foundation, four out the five eagle pairs have already produced eggs.

"A lot of us get a tremendous amount of egg joy through this and, as scientists, we acquire so much understanding of how the eagles behave," Hancock said.

"We see all the intimate behaviour."

Boat Exhaust Fumes Harming West Coast Killer Whales

Wildlife News

 

Just 87 orcas remain in the southern gulf between Seattle and Vancouver

THREATENED BY POLLUTION: Engine exhaust from boats may be having significant adverse health effects on endangered killer whales off the West Coast of Canada and the U.S., according to a new study.

Engine exhaust from boats may be having significant adverse health effects on endangered killer whales off the West Coast, a Canadian zoologist has found.

A two-and-a-half year study by Cara Lachmuth suggests that the orcas may be struggling with carbon monoxide emissions five times higher than those found 100 meters (328 feet) from Los Angeles freeways.

Lachmuth used computer modeling and mathematical equations to recreate various scenarios of exposure to pollutants. She then proportionately compared acceptable levels of toxins on humans to whale populations.

“There are different concentrations of pollutants under a wide variety of scenarios that I was able to recreate, and then I used those concentrations to figure out health-wise what that means to a killer whale,” said Lachmuth, of the University of British Columbia’s Department of Zoology.

She found that when cold ocean surface temperatures meet warm air, an inversion layer is created that prevents vertical airflow. This means the air can only move horizontally and keeps the pollutants close to the surface, accumulating right where the whales are breathing.

B.C. killer whales choking on boat exhaust: Study

VICTORIA — B.C.'s endangered population of southern resident killer whales face serious health issues from the exhaust emissions of pleasure and whale-watching boats, a study by a Victoria zoologist has found.

Over 2 1/2 years, Cara Lachmuth studied vehicle traffic and atmospheric conditions near the endangered southern resident killer whale population, which currently has 87 members.

What she observed is "worrying," Lachmuth said in an interview Thursday.

"We're right at the threshold of where you would expect to see health effects," said Lachmuth.

"Right now, there are no limits on the number of boats that can whale-watch. If you want to go fishing, you need a permit, but with whale-watching that doesn't exist."

Bald Eagles Starving After Poor Salmon Run

Bears also impacted

As a result of a weak, late-season chum salmon run, thousands of bald eagles that normally feed on salmon in rivers from Alaska to British Columbia are starving and forced to scavenge landfills to survive.



The birds depend on late fall runs of chum, the last salmon species to spawn each year, to carry them through the winter. But the 2010 chum run was much lower than usual, and not enough to sustain

the eagles

through periods of scarcity.



David

Hancock

, biologist, author, and founder of the Hancock Wildlife Foundation, says the eagles have few alternative food sources this time of year and are in the most desperate situation he’s seen in over 40 years of studying west coast wildlife.



“The alternatives, if the salmon aren’t there, are not very good for the eagles. There’s just nothing else, so they move into the local refuse and landfills. On one day, we had 1,387 eagles at the landfill—they were in desperation,” he says.



About 7,200 bald eagles that descended near Chehalis River in the southwest corner of British Columbia quickly exhausted the salmon supply, Hancock says. Just 10 days later

the eagle

population was reduced to 348 as they dispersed to find other food sources.



He says many eagles have resorted to “stealing” food from gulls and other birds at landfills in greater Vancouver, affecting these species as well. Compounding the problem is an especially cold winter that puts additional stress on their fight to survive.

The Bald Eagle Struggles in British Columbia: Nature's Dump Versus Ours

Wildlife News

By Nick Neely

One afternoon last week, David Hancock, a biologist, author, and publisher, pulled off the highway to talk to me on his cell phone while making his bald eagle rounds in the Fraser Valley, outside of Vancouver, B.C. He’s been studying birds of prey there, near his home, for 50 years, and this day was no exception, except it’s not so easy to get from A to B, to check your nests, when you’re being bombarded with eagle questions from across the country (and I wasn’t the only one). But Hancock jumped into this year’s story with such enthusiasm you’d never know he’d told it before. This is precisely what I’ve come to expect of those who have made a life of birds of prey.

Starving bald eagles so weak they fall from sky

Wildlife News

 

 

Poor chum salmon runs leave birds without any food

 
 
Starving bald eagles are falling out of the sky in the Comox Valley, a wildlife expert says.

Maj Birch, manager of the Mountainaire Avian Rescue Society, is caring for seven eagles.

Several others had died before they could be helped, she said.

"This is the most we have ever had," Birch said. "Many of them are downed before they are brought in. They are on the ground and they're too weak to fly away.

"Some of them are actually falling out of the sky.

One of them slid off a roof yesterday."

Fly Like An Eagle?

Wildlife News

As you might imagine, we get sent all manner of "Eagle" things, from great pictures to news stories. But the video shown below is kind of unique, even for us! Somewhere down on Whidbey Island, which is roughly 1/2 hour from these offices, this Bald Eagle is filmed having a fine time chasing a model airplane. Enjoy!

Mud Bay/Boundary Bay Dyke Trail 1-26-11

Wildlife News

 

Narration and Photos by PacNorWest (Doug)Click on image to download 

This is a flat trail that starts in Surrey, just a few minutes north of White Rock, BC. It is a dyke that runs along the shoreline of Mud Bay and Boundary Bay. It is mostly a compacted gravel surface, though sections where they were working were quite muddy. A short section is paved. There are many roads that access the trail along the route.


The Mud Bay end of the trail was mostly empty but there were a few walkers, bikers, and folks walking their dogs. The far end terminates in Boundary Bay park {near Tsawwassen} and there were many more folks enjoying the day along the trail as you get close to the park. Round trip is 40 kilometers {25 miles}. I rode my bike, and spent 6 hours doing it. It could be ridden in about 2 hours, but I stopped very often to watch birds and take hundreds of photos.


The day was mild {40's}, dry, hazy, a high white sky with occasional clearing and sunshine. The views towards the saltwater bay are right into the brightness, so poor for photography. I saw at least 60 eagles, probably many more. There were also Herons, Short-eared Owls, shorebirds {Dunlin, I think}, Northern Harriers, American Wigeons and others.
