Culasso, who was born blind, has spent more than twenty years recording the sounds of the Americas — trained under the neotropical sound archivist Jacques Vielliard, then at Cornell’s ornithology lab, and now contributing to the Macaulay Library. In 2014 he won the first season of National Geographic’s Supercerebros on his ability to tell birds apart by song alone. His most useful work may be the accessible birding route he designed in Colombia, the first in South America built for people who will only ever hear the birds.
