Swamp rabbits stay close to water. They’re strong swimmers that will dive and submerge to dodge a predator, and Texas records cluster around the wet, brushy edges of Aransas, Padre Island, and Brazoria rather than the dry brush country most people associate with Texas rabbits. Standing water and dense cover next to it are the pattern worth noting, not open pasture.

Reports jump hard in April, more than three times the count of any other month, while winter barely registers. That’s most likely spring breeding activity putting more rabbits in view of observers, not evidence that the population itself swells and collapses on that schedule.

NatureServe ranks the swamp rabbit S5, secure, in Texas, and it sits near the 90th percentile among Texas mammal records, one of the more frequently reported rabbits in the state’s occurrence data. That says more about how often people notice and report it than about how many actually live along these coastal drainages.
