The state or condition of being in estivation; also, the feeding or pasturing of animals during summer.
From estivate + -age (suffix forming nouns, often related to a state or action). Estivate comes from Latin 'aestivus' (of summer). The -age suffix creates a noun expressing a process or state.
While hibernation is famous for being winter sleep, estivation is summer sleep used by animals like lungfish and snails to survive droughts—it's equally amazing but way less popular in pop culture.
