What is it about birds going about their natural lives that provokes people to write slanderous songs about them and encourage their mistreatment?
Neil Gaiman's journal pointed me to "The March of the Sinister Ducks" (available for legitimate download). Its quirky humour disguises its true nature. It is a hate song. It is anti-avian propaganda. I group it together with Tom Lehrer's "Poisoning Pigeons in the Park" and Weird Al Yankovic's song advocating duck slavery: "I Want a New Duck".
Please don't think I'm trying to build a case on just three carefully selected songs. Vilification of birds has been nesting in the back of human consciousness for centuries. It surfaces every now and then with songs like "The Tennessee Bird Walk" by Jack Blanchard - a song that, while not exactly encouraging cruelty to birds, did suggest the possibility of bird abuse as both a source of humour and a mnemonic device for separated sweethearts. The practice of singing about avian abuse has a long tradition. Allow me to remind you of those French feather-fetishist phrases:
Alouette, gentile alouette,
Alouette, je te plumerai.
Anti-bird sentiment has reared its head in other ways too. I know of several songs accusing birds of sexual impropriety. e.g. "My Canary has Circles Under His Eyes" by Kohler/Pola/Golden and Jake Thackray's "The Bantam Cock". Sometimes the discrimination even descends to childish mud-slinging, as in "The Cuckoo is a Funny Bird".
I have a dre... er, no. That line's been overused. Let's just say it's time for the militant wing of the United Packbawkies to begin a retaliatory campaign. Don't say you weren't warned. All we need is someone to do for birds what Dana Lyons did for cows...
