The written accounts provide an unprecedented view of birds, bringing together decades of field expertise with insights drawn from billions of bird observations, photos, sounds, and videos contributed by birders to the Cornell Lab's eBird project and Macaulay Library. Designed to work with the digital tools that have introduced millions of people to birding, this guide delivers an experience no screen can replicate: side-by-side comparisons of similar species, quick access to key field marks, and detailed facing-page accounts that train the eye and sharpen field identification skills.

• Complements the strengths of the Merlin Bird ID app, bridging page and smartphone in a field-ready system for sound ID
• eBird integration includes global nomenclature, including subspecies, across the guide and Merlin, ensuring ease of identification and data sharing
• Distribution maps powered by eBird data transform millions of observations into new insights about bird distribution and abundance
