Health Canada is launching a review this spring on whether strychnine should be used to kill wolves. The Government of Alberta uses the poison to keep dwindling caribou herds alive. Alberta Trappers Association president Bill Abercrombie says strychnine is a horrendous way to kill an animal. “Strychnine initiates convulsions and the animal basically goes into […]
Do hibernating animals get cold? It might seem like a simple question, but scientists have long wondered exactly how bears, bats, snakes, and many other creatures can wait out the winter without freezing to death. According to a new study, that may be because hibernating animals don’t feel winter’s chill in the same way that […]
Normally when an animal is scared, it either remains very still and slows its heart rate and metabolism in hope that danger will pass—like a possum playing dead, in an extreme case—or the body revs up to power a “fight or flight” response.

He concluded the animals’ potential to change local […]
In the popular TV series “The Walking Dead” humans can hide from zombies by covering themselves in zombie guts, masking their scent. The California ground squirrel (Otospermophilus beecheyi) uses a similar tactic to hide from a major predator, the rattlesnake, which relies on smell to track down its prey.
The Swainson’s Hawk (Buteo swainsoni) is listed as threatened in California. Its numbers have declined significantly in parts of the western United States; and in the western Canadian prairie, reproduction of the Swainson’s Hawk has dropped since the mid-1980s, following a decline in its main prey species, Richardson’s ground squirrel. In 1995, satellite telemetry was […]
First, this particular area of south Texas is called the Rio Grande Valley, more specifically, the Lower Rio Grande Valley. It is where the Rio Grande River meets the Gulf of Mexico, and is considered one of the most biologically diverse regions in North America, where over 500 species of birds have been documented.
