The Status of the Wolf Part 7: The Red Wolf

© Brad McPhee

The red wolf of the Southeastern United States is currently considered by most taxonomists as well as the U.S. Fish and Wildlife Service (under the auspices of the Endangered Species Act) to be a species of wolf, Canis rufus, distinct from the gray wolf, Canis lupus [1]. As a unique type of wolf, it is one of the most endangered mammals on the planet.

Similar in size to the Mexican wolf (see Part 6: The Mexican Gray Wolf), the red wolf is somewhat smaller than most gray wolves, adults averaging between 50 and 80 lbs (about the size of German shepherd dogs).

Mystery of British Columbian Sockeye Salmon Run

Sockeye: sometimes Called the Money Fish. - cacophony


After years of catastrophic decline the sockeye salmon run up the Fraser River in August 2010 has hit record numbers and surprised everyone. 

The headline in the Vancouver Sun (August 25, 2010) says it all: “Fishermen ‘excited’ for Largest Sockeye Salmon Run in nearly a Century.”

The Pacific Salmon Commission estimates the 2010 season will see 30 million sockeye salmon returning to spawning grounds; that’s 20 times more than arrived in 2009.

When Do the Salmon Run?

Bald Eagle Biology

When they're chased!  When not swimming!

The Pacific Salmon spawn is highly variable, depending upon individual historic timing for a stream, the species and the geographic location.  Still not much help!

In general terms the earliest salmon runs are in the north and as the season progresses the runs are maturing and spawning farther south.  So the earliest runs occur in NW Alaska  -- some of the fish coming into the rivers as early as April and May, immediately after the rivers thaw. Then the peak spawn happens during the summer months and into the early fall.  However, by late fall in the north you are starting to get early freeze-ups, both preventing the salmon accessing the shallows and, more importantly, preventing the hatching fingerlings finding any insects upon which to feed.

So once the freeze ups start putting the dead and dying carcasses out of reach under the ice, the eagles are generally forced south.  This means that in the years of early and strong early freeze ups we get thousands more eagles forced early to our southern waters that are still open.  In most years the rivers around southern BC, and particularly our Harrison River complex, the heavy die-off is not available until late October or early November.  .. read more ..

What Drives the Number of Nests in a Territory?

Alternative Bald Eagle Nests - a Plethora in Some Areas - Not in Others- Why?

Here is a good Thesis topic -- but it needs a Sponsor!

In most of nature there are usually multiply reasons why some behavior or action takes place. 

Why do some eaqles  make several nests? In other active territories only one nest is ever found. Obviously some make a new nest to replace one that has been destroyed by the weather. The nest used for several years very successfully, simply rotted out and fell, partially or wholly to the ground.  In other cases the tree blew over.  In many of the urban areas the availability of strong cedar, Sitka spruce or

Bird man of Surrey tries to nurture nature

As David Hancock swings open the gate to his yard, he is greeted by his regular houseguests, including Bahama pintail and blue-billed ruddy ducks.

“Hello guys, how are you?” Hancock says in a melodic voice, as the waterfowl wade through a pond stretched across the lawn.

The South Surrey acreage is home to about 20 bird species, some permanent residents, others just visiting.

A pair of Canada geese come to Hancock’s property annually to raise their young, and this year they have four babies just learning to fly. Hancock, a biologist, says the youngsters will have seven to 10 days to master the skill before the family leaves and returns next February.

Other feathered members of the backyard community are heard long before they are seen. As Hancock navigates his way along the pond’s rock wall, he stops to listen to the cry of a nearby baby pileated woodpecker. It’s the first time he has heard its call.
