Numerous people worldwide were appalled by this experiment that didn't work, and now a team of highly respected scientists has formally responded to this gruesome killing spree. In a paper just published today called "Maintaining Ethical Standards during Conservation Crises," by Ryan K. Brook, Marc Cattet, Chris T. Darimont, Paul C. Paquet, and Gilbert Proulx in the journal Canadian Wildlife Biology & Management, these scientists write, "Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and the use of strychnine baits. Both of these methods raise critical questions with regard to animal welfare. When it is necessary to kill an animal, reliable humane procedures must be used to avoid pain or distress, and produce rapid loss of consciousness until death occurs. Also relevant are formal approvals by government and institutional animal ethics committees that adhere to Canadian Council on Animal Care (CCAC) guidelines. Shooting a moving animal from a helicopter is prone to error and not conducive to shots that quickly render animals insensitive to pain or produce a consistently quick kill. Strychnine does not meet the CCAC's criteria for an acceptable killing method, and is specifically prohibited as an injectable option for euthanizing animals. Its use under uncontrolled conditions at bait sites is likely even less suitable."
