“A flock of starlings.”
–from C.E. Hare’s The Language of Field Sports, 1939
Therefore, a murmuration of starlings.
There are so many strange words to denote groups of animals, and apparently there is one for each kind of animal.
My favorite may be “a murder of crows.”
But I also like
“A conspiracy of lemurs”
“A cauldron of bats”
“A clowder of cats” or “A kindle of kittens”
“A romp of otters” (how apropo!)
“An ostentation of peacocks” (again appropriate)
“A quiver of cobras”
“A maelstrom of salamanders”
