Texas Toad vs Western Toad
A Texas toad and a western toad are both North American toads occupying very different climates, and each has adapted its breeding strategy to match, one built around sudden desert rainstorms, the other around the quiet demands of a cold mountain existence.

Texas Toad vs Western Toad: common questions
Why does the Texas toad breed so suddenly while the western toad does not?
The Texas toad occupies an arid desert range where breeding pools only form after heavy summer rainfall, so the species breeds explosively within a short window to take advantage of temporary water, while the western toad's mountain habitat offers more predictable seasonal conditions, removing the need for the same rain-triggered urgency.
Do both toads have a mating call?
No, the Texas toad produces a distinctive high-pitched trilling call typical of many toad species, but the western toad is unusual in that males generally lack a functional vocal sac and produce no real mating call at all, relying instead on direct physical contact to locate mates.
Which toad lives at higher elevation?
The western toad tolerates a much broader and higher elevation range, having been recorded at sites well above 3,000 metres in the Rocky Mountains, while the Texas toad is restricted to lowland arid desert and grassland habitat considerably closer to sea level.
