Mr. Matthiessen was a man of many parts: littérateur, journalist, environmentalist, explorer, Zen Buddhist, professional fisherman and, in the early 1950s, undercover agent for the Central Intelligence Agency in Paris. Of his more than 30 books, nonfiction works far outnumbered the novels and short-story collections, but he considered fiction his first and highest calling. Peter Matthiessen was born on May 22, 1927, in Manhattan) - http://www.nytimes.com/2014/04/06/books/peter-matthiessen-author-and-naturalist-is-dead-at-86.html?_r=0 found: Birds, 2018:title page (foreword by Peter Matthiessen)
