Cathartes aura is the latinized nomenclature (according to the Linnaeus classification scheme) of the turkey vulture. According to a Wikipedia entry:
The Turkey Vulture is a scavenger and feeds almost exclusively on carrion. It finds its food using its keen eyes and sense of smell, flying low enough to detect the gasses produced by the beginnings of the process of decay in dead animals. In flight, it uses thermals to move through the air, flapping its wings infrequently. It roosts in large community groups. Lacking a syrinx—the vocal organ of birds—its only vocalizations are grunts or low hisses.
Now, it would be mean and insulting to call Rex Murphy a turkey vulture - mean and insulting to such a useful bird as the turkey vulture. But here I am defending the bird.
If you looked up "ingratiating" in the dictionary, you'd see a picture of Rex Murphy because like the meaning of the word: intended to gain approval or favour, much of what Rex Murphy says oozes shamelessly out of his mouth that while calculated to impress rather gives the impression that he's condescending without actually stooping down to our level of intelligence.
Lacking a syrinx, the Murph relies almost solely on his piercing glaze to intimidate - there is something resembling intelligence behind them eyes but it is more cunning and vigilance for opportunities to snatch up morsels of what does not belong to him. Nothing that he vocalizes is ever really original if mean and vindictive clumsily designed and calculated to cozy up to his political betters.
CBC's The National keeps him like a cruel curiosity because it is just so compelling to watch him work himself to an orgasmic state like a pig in poop. For shame, CBC. Shame on me as well for my morbid curiosity.
