Read about Chipilo Crisopario and Golden-cheeked Warblers in this article from Audubon:
Chipilo has become a cornerstone of Pronatura’s environmental education, a fun tool for helping to instill a conservation ethic in children, with the hopes that they will care about and protect the natural world throughout their lives. The book has reached more than 3,000 children, mostly in Chiapas, many of whom are Tsotsil. In 2018 Pronatura had the book and accompanying lessons translated into Tsotsil. The Golden-cheeked Warbler doesn’t have ancient cultural significance for the community, but there are parallels: Just as the endangered songbird’s plight has long been neglected, so has their language. Translating Chipilo into Tsotsil is just one small part of a growing effort to dignify the country’s more than 68 Indigenous language groups, which are in turn divided into 364 language variations.
