Broad-billed Hummingbirds (and most hummingbirds) are quite solitary and territorial, so you may not often see them congregating in large groups, However, the names for groups of hummingbirds are very poetic and apt. I don't know who came up with these terms, but they seemed to have a lot of fun doing it! So, without further ado, the terms used to describe a group of hummingbirds include (but are not limited to) the following: • A charm of hummingbirds • A glittering of hummingbirds • A shimmer of hummingbirds • A bouquet of hummingbirds • A hover of hummingbirds
