All of the names in this list may be used by birders who wish to display their knowledge, although it is probably linguistically inaccurate (and it is bad manners) to interrupt someone who refers to “a flock of swans” by saying, “Surely you mean a whiteness of swans.”
The names are still fun to know and perhaps useful in some situations, so here is a list of names for groups of birds.
(Format: a [group name] of [bird name] i.e., a band of jays)
