They shed their skin for the first time at 7 to 10 days of age. Hatchlings are typically 10 to 17 inches long. Eggs grow in width and mass during the development period.Įggs take about 60 days to hatch. The whitish eggs have rough, leathery shells and average 1½ by 2 inches. Communal nests have been reported, but they are not common. The nest may be out in the open or under a large rock or log in loose, sandy soil. In June or early July, females lay a single clutch of three to 24 eggs (average of 12) in a self-dug nest. Mating and Hatchlingsīullsnakes mate in May. Killing even one snake will benefit the rodents. Landowners battling rodent populations in croplands or grasslands benefit from having snakes nearby. Other prey include frogs, ground-nesting birds, and bird eggs. Bullsnakes are at risk when trying to subdue a large rodent, and may be badly bitten or, in rare instances, killed in the process.īullsnakes are extremely beneficial predators, eliminating numerous pocket gophers and ground squirrels. What Do They Eat?īullsnakes are constrictors that eat gophers and a variety of other small mammals, including mice, voles, ground squirrels, and tree squirrels.
Their active season generally ends in late September or early October. They are fond of basking on warm sand, rock, or pavement. Bullsnakes can climb, but they spend most of their time foraging and resting in rodent burrows. They are mostly diurnal – meaning they are active during the day. Some snakes travel over 1.5 miles during the summer. They have an average home range of 18 acres but can use over 500 acres during their active season: late spring and summer. In the summer, bullsnakes use large areas of land.
In the Twin Cities area they hibernate in gopher tunnels and other burrows that go below the frost line. Bullsnakes thrive in sandy-soil habitats where burrowing rodents are common.īullsnakes emerge from hibernation in late April or May. They prefers native prairies, old fields, pastures, oak savannas, and bluff prairies that are located on steep hillsides. Habitat and Hibernationīullsnakes are snakes of open country. The pattern of juvenile bullsnakes is similar to adults, but their overall color is lighter. Many individuals show a pronounced color change from head to tail. The chin and belly are pale yellow, and the belly has several square or rectangular dark spots. The blotched pattern is less obvious near the head but becomes bolder near the tail, which has black or reddish-brown bands. Their bodies are straw-yellow or light brown, with dark-brown or reddish-brown blotches down their backs. "bull snake" by photogramma1 is licensed under CC BY-SA 2.0.

Identifying Bullsnakesīullsnakes are the longest snakes in Minnesota, reaching a length of more than 6 feet. Many records of bullsnakes in Minnesota come from counties bordering the Mississippi, Minnesota, and St. In Minnesota, bullsnakes are found in the southern half of the state. Rangeīullsnakes range from western Wisconsin and Illinois south to Texas and west to the Pacific coast.

In this post, learn all about bullsnakes, their habits and how to identify them, then find out more about how we reintroduced them into the prairie at Crow-Hassan and tracked their success. Bullsnakes, a state-listed species of special concern that has become scarce in Minnesota, fit the bill. If you read our post on species reintroduction, you know that we often choose to reintroduce a species that we can provide adequate habitat for, easily collect from another area, and that is likely to thrive in the long-term. It took time, patience and careful record-keeping, but since then we’ve seen steady growth in the population. In 1991, Three Rivers began an ongoing effort to reintroduce bullsnakes, also known as gopher snakes, into Crow-Hassan Park Reserve.
