Bullsnake (Pituophis catenifer sayi)
This impressive-sized constrictor is generally yellowish in coloration with a series of squarish, chocolate-brown dorsal blotches. Smaller, irregular blotches occur on the sides. The blotching becomes more regular and with higher contrast toward the tail. Although head patterning can vary, a dark line between the eye and jawline is typically present. This species has an enlarged rostral scale for digging.
Other conspecifics are called Gopher Snakes.
This is a species of the Great Plains. It occurs in prairie habitat. In its range, it prospers in an agricultural setting.
This species is a known burrower, either digging itself under loose, sandy soil or taking over an existing rodent burrow. It may also hide in large grass clumps. Especially during the spring, it may be observed basking. Primarily diurnal, it switches to a more nocturnal pattern of activity during the hottest part of summer.
Breeding occurs in spring. Females lay their eggs in early summer. Hatching occurs in late summer.
This species is known to prey upon a variety of mammals. Birds and their eggs may also be consumed.
Prey is searched for actively and, when found, is grasped quickly and constricted with strong, powerful coils.
Although some individuals seem to calm with handling, a newly captured or cornered specimen is likely to put on an impressive display! This display may include coiling, raising of the head into striking posture, loud hissing, and vibrating of the tail. For some individuals, this is used more as a bluff, but other individuals will back it up with biting and pooping/musking.
As this species is not confirmed to occur in the state, no special status is attributed. In other parts of its range, it is generally well-recognized by farmers as a beneficial rodent-reducing machine. However, warrantless killings and road mortalities are still a concern.
