Heard a Great Basin spadefoot toad calling at approximately 1540 hrs. on a warm, sunny day.

Found one adult under wood debris, adjacent to a cattle pond at 13:05. Observed 50+ tadpoles in cattle pond. Heard multiple calls beginning at twilight, lasting throughout the PM.

Found in soft sand burrow on dike
