The Forages are also divided in legume forages and grass forages. Maize silage is one of the most valuable forages for ruminants. The yellow anaconda forages predominately in shallow water in wetland habitats. Omnivorous, it forages for invertebrates, fungi and plants at night. The northern parula forages mostly or entirely on terrestrial invertebrates. It forages at night and sleeps during the day in tree roosts. The little brown bat forages along the edges of vegetated habitat. This bird commonly forages in flocks, although it sometimes forages in pairs or by itself. The imperial eagle often forages mainly in open areas, including wetlands and agricultural areas. This species of tropicbird usually forages alone. In solitary nesting, the founding bee forages, builds cells, lays the eggs, and guards. During drier times, it forages for insects longer as they become more scarce. The off duty parent forages in flocks with others of the same species. The female forages significantly more than the male during most stages of breeding. This cormorant forages by diving and capturing its prey in its beak.
