>>Circling vultures bring attention to poachers, so the scavengers were likely poisoned by illegal hunters hoping to evade detection
More than 500 endangered vultures died in northern Botswana after feasting on elephant carcasses laced with poison, the country’s government announced last week. Conservationists say that poachers targeted the birds—two tawny eagles and 537 vultures comprising five different species—because their scavenging activities, particularly circling carrion, can alert authorities to hunters’ presence.
“Vultures are sentinels to poached animals, so they’re directly being targeted,” Kerri Wolter, CEO and founder of conservation charity VulPro, tells The New York Times’ Kimon de Greef.<<
