twitching

Synonym discussion
Sense: verb/1
'Twitch' describes a small, quick, involuntary movement of a body part — an eyelid or finger twitches — and is the most everyday word for this. 'Jerk' suggests a larger, more forceful movement; the whole body or limb may move abruptly, as in a startle reaction. 'Spasm' is a medical term for a sudden, strong, and often painful muscle contraction that lasts longer than a brief twitch. 'Quiver' implies a fine, trembling vibration rather than a single pull — lips quiver before someone cries. 'Flutter' refers to rapid, light repeated movements, such as an eyelid fluttering under bright light. As a rough guide: if the movement is tiny and singular, use 'twitch'; if it involves trembling repetition, 'quiver' or 'flutter'; if violent and sudden, 'jerk'; if sustained and painful, 'spasm'.

Etymology
The verb 'twitch' comes from Middle English 'twicchen', meaning to pull sharply or snatch. It is related to the Old English word 'twiccian' (to pluck). The sense of an involuntary muscle movement appeared in the 1400s. The noun describing the birdwatching hobby is much newer — it emerged in British slang during the late 1900s among birders who 'twitched' (rushed) to see rare species that had been spotted.
