I like observing them, reading about them, grappling with species and subspecies identification, and even—on a good day—talking about sparrow taxonomy. Peterson Reference Guide to Sparrows of North America covers 61 species of the New World sparrow family Passerellidae that breed in Canada, the United States, and northern Mexico.

Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. With the breeding colony concentrated on one small island this species is vulnerable to a catastrophic weather event.

Does the word define a species within country terms, regional terms etc? Is the term defined at the sub-species or full species level in terms of classification?
