Murmuration
noun /ˌmɜːmjʊˈreɪʃ(ə)n/ — The hypnotic collective movement of a flock of starlings.
Definition
The collective movement of starlings in their huge winter flocks — the fluid, shapeshifting formations made by thousands of birds moving as one, produced by each bird responding to the movements of its nearest neighbors.
Beyond the definition
Murmuration is one of those natural phenomena that defeats description until you see it — a flock of thousands of starlings moving as one body, rippling and contracting and extending. No conductor, no plan — just the mathematics of neighbor-following producing patterns of extraordinary beauty.
Origin & history
From Latin murmurare (to murmur) + -ation. The collective noun for starlings was used historically; the specific word murmuration gained cultural currency in the 2010s when drone footage revealed the full scale of the phenomenon.
