George Oliver Shields (26 August 1846 – 11 November 1925) who also wrote under the pseudonym Coquina was the editor of a pioneering American magazine for outdoors sports Recreation where he also took on a role as an activist for the conservation of wildlife.

In a column in the magazine, he began to shame fish and game sportsmen who he deemed as not following sporting ethics.

He then worked as an immigration agent, trying to get stock investors to support the Pecos Irrigation and Improvement Company at Carlsbad, New Mexico (then called Eddy).

He founded the outdoors sporting magazine Recreation in 1894 and took on the cause of wildlife conservation along with William T. Hornaday by heading the Camp Fire Club of America from 1897 to 1903.

Shields ran images of hunters that he called as "game-hogs" with libelous captions such as "I pity the dogs that were forced to associate with such miserable swine as these.
