I'AN:ilIEROPIIIS BAIRDI (Baixl's Ratsnake). DIET AND FOR-AGING BEHAVIOR. A Pantherophis bairdi was found inside a
cave (La Sepultura) in the municipality of Cd. Victoria, Tamau-lipas, M6xico (23.7756667"N, 99.22S8056"W datumWGSB4; elev.597 m). The snake was found coiled 2 m above the ground alongone of the rvalls of the cave attempting to catch bats of the spe-cies Leptonycteris curasoae (Fig. l). Other species of bats foundand identified in this cave included Desmodus rotundus, Di-phylla ecaudata, and Pteronotus parnelli. Previous reports men-tion that P. bairdi preys on rats, mice, bats, birds, bird eggs, andlizards, without reference to specific species or families of eachgroup (Schulz 1996. A Monograph of the Colubrid Snakes of theGenus Elaphe Fitzinger. Koeltz Scientific Books, Czech Republic.439 pp.). Schulz (1996, op. cit.) mentions that caves are inhabitedby several species of rat snakes at least temporarily. For example,Pantherophis guttata, P obsoleta, and Senticolis triaspis wererecorded from caves occupied by bats, which served as prey.Moreover, the only known P bairdi record in this municipalitywas published in 2009, but referred to a specimen found byT. W.Walker in 1969 (Farr et al. 2009. Herpetol. Rev. 40:459-467). Thus,this record represents the second municipality record in a spanof over 40 years. The snake and bats were not caught or collectedand were identified photographically and with the help of LuisCanseco-Mdrquez and Arnulfo Moreno-Valdez, respectively. Wealso thank David Lazcano-Villarreal for revising the manuscript.

PANIIIEROPHIS SP/IOIDES (Gray llatsnake). REPRODUC-TIVE BEHAVIOR / ARBOREAL MALE COMBAT. The goal of ma_.combat in snakes is to establish dominance over an oppone::through physical superiority (Gillingham 1987. In Seigel ei 'leds.l, Snakes: Ecology and Evolutionary Biology, pp. 184-2t:McGraw-Hill Publishing Co., NewYork). Male ratsnakes compe:.for mates by participating in dominance "combat dances" (Rr:-ley 1971. I. Herpetol. 5:65-66; Stickel et al. 1980. Amer. Midl. \a:103:l-14); although the role of this behavior is not fully unde:-stood (Rigley, op. cit.). The arboreal habits of species in the Par-therophis obsoleta complex are also well documented (Ernst an :Ernst 2003. Snakes of the United States and Canada. Smithso:_-ian Institution Press., Washington, D.C., 68l pp.), and arbore:mating has been noted in P o. obsoleta (Padgett 1987. Catesbe--ana 7:27-28), but to our knowledge, arboreal male combat ha:not been reported.
On 24 May 2006 at 1200 h, we observed a pair of free-rangir:.male Pantherophis spiloides engaged in arboreal combat on ri:.Camp Shelby Joint Forces Training Center, Forrest Co., Missi.-sippi, USA. The snakes were found entwined approximately 5 r:-
above ground, hanging from a broken limb in a Quercus mar:-landica (Fig. l). The smaller male (SVL = l4l cm, 612 g) conrir-ued to break contact and move up the tree, and was followed b'.
