Hudson spent his youth studying the local flora and fauna and observing both natural and human dramas on what was then a lawless frontier, publishing his ornithological work in Proceedings of the Royal Zoological Society, initially in an English mingled with Spanish idioms. In Argentina, Hudson is considered to belong to the national literature as Guillermo Enrique Hudson, the Spanish version of his name. A town in Berazategui Partido and several other public places and institutions are named after him.
