big brown bat

The big brown bat (Eptesicus fuscus) is an insectivorous mammal found from southern Canada to northern South America. It belongs to the genus Eptesicus, which includes over 30 species commonly known as big brown bats or serotines. These bats are relatively slow fliers and often roost in buildings, tree hollows, or caves.123

Big brown bats are part of the vesper bat family and are widely distributed globally. While most bats are beneficial to humans by consuming insects, aiding in pollination, and dispersing seeds, vampire bats can be pests to livestock. The droppings of insectivorous bats, known as guano, are also used as fertilizer.24
