Hamilton Alden Tyler was born in Fresno, California, in 1917. His father was an ardent field ornithologist, a contributor to Bent's Life Histories, and the author of a study on nesting habits of birds. Young Tyler's interest in insects and earliest training began as an egg boy, climbing up trees and over cliffs for various naturalists.
