Corado was born in a small village of El Chicał, Morazan, El Progreso, Guatemala among six siblings. In 1968, at age 8, Corado and his family moved to Guatemala City. He attended school in the morning and to help his family survive, he shined shoes in the afternoon and asked for leftovers to feed his siblings. Some days he did not collect enough food and visited the dump to look for food for himself. In 1981, Corado emigrated to the United States. He went to Hollywood, where he started as a gardener for the Donald L. Bleitz Wildlife Foundation in 1982. Bleitz passed away in 1986 and requested that all study skins go to the Western Foundation of Vertebrate Zoology, which became the largest egg and nest collection in the world, founded by Ed Harrison in 1956. Corado worked alongside Harrison, building his knowledge of oology and collaborating on ornithological research.
In 2001, Corado started a bird conservation project in Guatemala. By 2004, with the help of Linnea Hall and the support of Western Foundation of Vertebrate Zoology he created a campaign called the Guatemala River Project to work towards cleaning the heavily polluted Motagua River. He and Hall collaborated on publications such as Egg & Nest, which emphasizes the diversity that can be found in bird eggs and nests.
In 2016, he published his autobiographical book The Adventures of René Corado, The Shoeshine Boy, bilingual and illustrated. 
On Nov 11, 2019 he was honored with the Order of the Quetzal. Established in 1936, it is bestowed by the Government of Guatemala. The award acknowledges officials of nations, organizations and other entities whose artistic, civic, humanitarian, or scientific works merit special recognition .Order of the Quetzal#cite note-usaid.gov-1
