The western toad (Anaxyrus boreas) is a large toad species, between 5.6 and 13 cm (2.2 and 5.1 in) long, native to western North America.[1][3][4] A. boreas is frequently encountered during the wet season on roads, or near water at other times. It can jump a considerable distance for a toad. Breeding occurs between March and July in mountainous areas, and as early as January in lower-elevation regions. The female lays up to 17,000 eggs stuck together in strings that adhere to vegetation and other objects along water edges.[5]
