In behavioral ecology, hyperphagia is a short-term increase in food intake and metabolization in response to changing environmental conditions. It is most prominent in a number of migratory bird species. Hyperphagia occurs when fat deposits need to be built up over the course of a few days or weeks, for example in wintering birds that are preparing to start on their spring migration, or when feeding habitat conditions improve for only a short duration.[1][2]
