The Sibley Guide to Birds

This book by David Allen Sibley came up once on Tim Ferriss in the episodes we index. That mention was a genuine on-air recommendation, not just a passing reference. The people who brought it up: Steven Rinella. Every occurrence below links to the episode page and to the exact second it was said on YouTube.

Watching and identifying birds quickly leads to curiosity about how and why birds do the things they do. How does a tiny chickadee survive subzero temperatures? How does an albatross cross miles of ocean without flapping? Why do male wood-warblers have two distinct song types? The answers, or proposed answers, exist in technical papers and in textbooks, but such resources are often inaccessible to birders, and the information of most interest to amateurs is frequently embedded in a wealth of technical detail.
