Woodhouse's Toad (Anaxyrus woodhousii)
19 May 2015: Walked about Avondale Park and Cooper Creek and came upon a Woodhouse's Toad (Anaxyrus woodhousii). This occurred during the daytime. Woodhouse's Toad is the predominant toad in this stretch of Cooper Creek. Its counterpart frog in the creek is Blanchard's Cricket Frog. NatureServe prepared a range map for Woodhouse's Toad in June 2005 and found that its range extended from the border with Canada to the north up the midwestern section of the United States and that its southern range extended through most of Texas south into parts of northeastern Mexico including the states of Chihuahua, Coahuila and most likely Tamaulipas. And to the west and southwest in New Mexico, Arizona, and southeastern California its range also extends into Baja California Norte, Sonora, and parts of Durango. These places constitute its southern range (the link to the range map in question is provided below). Because it occurs throughout a large central portion of the United States and small parts of southcentral Canada and northwestern and northeastern Mexico, Woodhouse's Toad is and has been an authentic resident of the Western Hemisphere.
