Western Toad

Anaxyrus boreas

Summary 3

The western toad (Anaxyrus boreas) more commonly known as Bufo boreas (both names accurate) is a large toad species, between 5.6 and 13 cm long, of western North America. It has a white or cream dorsal stripe, and is dusky gray or greenish dorsally with skin glands concentrated within the dark blotches. Its parotoid glands are oval, widely separated, and larger than the upper eyelids. It has a mottled venter and horizontal pupils but lacks cranial crests.

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.[2]

B. boreas is frequently encountered during the wet season on roads, or near water at other times. When handled adults often vocalize, making a sound like a peeping chick while struggling. It eats any type of insect it can catch. It can jump a considerable distance for a toad.
This toad frequents a wide variety of habitats such as, desert streams, grasslands, woodlands, and mountain meadows, and can be found in or near a variety of water bodies (Stebbins 1985).
