means The practice of observing and identifying wild birds in their natural habitat, usually with binoculars, a notebook, and a suspiciously large amount of waiting.

from A straightforward 20th-century formation — 'bird' plus the activity-suffix '-ing' — that emerged as enthusiasts wanted a word distinct from 'bird-watching,' which sounded too passive for people trekking through swamps at dawn.
