birdwatching

Synonym discussion
Sense: noun/1
All four words involve looking at birds, but they differ in tone and seriousness. 'Birdwatching' is the everyday word: a relaxed outdoor hobby that includes anyone from a child with a feeder to an adult on a guided tour. 'Birding' is the same activity but signals a more dedicated, often North American, hobbyist who keeps lists and travels for sightings. 'Ornithology' is the formal academic field, practised by university-trained scientists who publish research on bird biology and behaviour — not a hobby. 'Twitching' is British slang for a particular sub-culture: rushing across the country whenever a rare bird is reported, just to add it to a personal list. So a retiree with binoculars in the garden is birdwatching; a researcher banding chicks for a study is doing ornithology; a fan driving overnight to glimpse a rare warbler is twitching.
Common collocations
Etymology
A straightforward English compound: 'bird' plus 'watching', the gerund of the verb 'watch'. The compound noun appears from the late 1800s as middle-class leisure expanded and gardens, parks, and binoculars made the hobby practical. 'Bird' traces back to Old English 'brid' (originally 'young bird, chick'); 'watch' comes from Old English 'wæccan', meaning 'keep awake, observe'.
