Some Birdwatching Resources


Birdsong, Don Stap Birdsong, Don Stap. From the promotional material: "Following one of the world's experts on birdsong from the woods of Martha's Vineyard to the tropical forests of Central America, Don Stap brings to life the quest to unravel an ancient mystery: Why do birds sing and what do their songs mean? We quickly discover that one question leads to another. Why does the chestnut-sided warbler sing one song before dawn and another after sunrise? Why does the brown thrasher have a repertoire of two thousand songs when the chipping sparrow has only one? And how is the hermit thrush able to sing a duet with itself, producing two sounds simultaneously to create its beautiful, flutelike melody?"
