Science Saturday: Shrews, Coyotes, and Wolves

(I didn't have any pictures of the topics, so I grabbed a moon to howl at. ;~)

I saw a coyote a couple years ago on my way to dance. It was pretty cool!

A few mildly intriguing things:
  • The name "Shrew", means ill-tempered and scolding women, started off as "screawa", Anglo-Saxon, for venomous animal. The word changed to shrew in Middle English. (This is where the word "shrewd" came). So why is a Shrew called a Shrew?
  • A Shrew has poisonous saliva produced by glands in their lower jaw. It's not strong enough to kill a human but it can stupefy a mouse and give it convulsions.
  • They are voracious insect eaters. They eat more than their weight a day. Some species, if they go with out food for a couple house, die from starvation. 
  • Wolves are a part of the canine clan, so they have characteristics that are found in domestic dogs.
  • Wolves are carnivores, which means they are meat eaters. They are also social and prefer to travel in packs. They were/are diminishing, so many efforts are being made to keep them from extinction.
  • Unlike most canines they are also coursers which means they have the body and stamina to chase prey or run for long distances!
  • With wolves diminishing, coyotes have been increasing. Some people thought they were wolves, or an interbreed of wolves and dogs, but neither is true. Coyotes are coyotes.
  • They used to live out west and slowly around the 1940's they started becoming established here in the East. Eastern Coyotes are merely adventurous westerners. ;~D
  • They can interbreed with dogs, but as numbers have increased they aren't as likely to.
