Scientific Name: Bufo alvarius
Range: From Central Arizona to southwestern New Mexico and Sinaloa, Mexico.
Diet: Eats lizards, invertebrates, small mammals, and amphibians.
Temporal Activity: They are nocturnal during the hot summer months. Their activity is stimulated by rainfall, therefore they are active from late May to September during this rainy season.
Breeding: The male makes a call to his mate which is weak, sounding somewhat like a ferry-boat whistle. Eggs are laid in strands in temporary rain pools and permanent ponds. Larvae metamorphosis takes six to ten weeks. Members of this species live about ten years.
Predators: This toad is a predator to dogs. It has extremely potent, defensive toxins that are released from several glands in the skin. These toxins are strong enough to kill full-grown dogs.
