What does birder mean?
A birder is someone whose pastime involves observing, identifying, and often recording wild birds. Unlike an ornithologist, who studies birds scientifically, a birder pursues the activity recreationally, whether casually from a kitchen window or with the dedication of travelling great distances to see rare species. The term is widely used within the birding community itself and carries a friendly, enthusiast tone; in British usage, 'twitcher' denotes the more obsessive subset who rush out to spot rarities. Birders commonly maintain life lists documenting every species they have seen, and the hobby spans all levels of commitment. The word is a straightforward compound of 'bird' with the agentive suffix '-er', denoting one who performs the action. Its popularity reflects the growth of recreational birdwatching as a mainstream outdoor pursuit worldwide.

Etymology of birder
Birder is formed by combining the noun 'bird' — of Old English origin ('bridd'), originally meaning a young bird or chick — with the agentive suffix '-er', which denotes a person engaged in an activity. The term emerged as a natural alternative to 'birdwatcher', gaining currency in the twentieth century as recreational birdwatching grew in popularity, particularly in North America. It belongs to the same productive pattern that yields words like 'runner' or 'swimmer'.
How birder is actually used
Informal to neutral in register. In British English, 'twitcher' refers specifically to a birder who chases rare birds, while 'birder' is broader. The word is common among enthusiasts themselves, whereas 'ornithologist' implies scientific study rather than recreation.
