Because hummingbirds typically live solitary lives, there is no one name to describe a group of hummingbirds. However, a common term to refer to a group of migrating hummingbirds is a hover.
In Hummingbird Agile, a hover is a group of leaders, producers and specialists who are dedicated to the perpetual-discovery, continuous-delivery process for a product line or solution. Hovers are long-standing, meaning they stay together over a long period of time, and they consist of a pool of skill sets that align to the type of value they deliver within a three-week delivery circuit. For large enterprise applications and product lines, there can be multiple hovers who work in a synchronous, cross-pollinating manner without extra overhead added to the budget.
