Beck has been blamed for having collected a sample of Guadalupe caracaras in 1900 which were being exterminated by goat herders who viewed the bird as a predator. At the time he assumed the birds were common on Guadalupe Island, but in retrospect he wrote that those he collected might have been the last. Beck also collected, as museum specimens, three of the last four individuals of the subspecies of Galápagos tortoise Geochelone nigra abingdonii, the Pinta Island tortoise. The last individual of that island's tortoise population became known as Lonesome George when it was found on Pinta Island in November 1971.
