Reproductive and Ecological Observations on Tantilla rubra cucullata from Big Bend National Park, Texas (Serpentes: Colubridae)
Easterla DA. 1975. Reproductive and Ecological Observations on Tantilla rubra cucullata from Big Bend National Park, Texas (Serpentes: Colubridae). Herpetologica. 31(2):234-236
On 16 July 1973, a recently killed gravid Big Bend black-headed snake, Tantilla rubra cucullata, was found at the Panther Pass parking lot. Dissection revealed 2 eggs. Limited information available suggests that the species is secretive and nocturnal with narrow ecological tolerance, e.g., weather, especially rainfall. In August 1974, an adult male was captured alive; it had an unrecorded collar pattern. This suggests that collar pattern may not be a valid criterion for subspecies designations of T. r. cucullata and T. r. diabola
