Evidence Of Non-Strike Induced Chemosensory Searching By Eastern Copperheads (Agkistrodon Contortrix) During Cicada Predation, Henderson Cyrenius Gull Jan 2021

Evidence Of Non-Strike Induced Chemosensory Searching By Eastern Copperheads (Agkistrodon Contortrix) During Cicada Predation, Henderson Cyrenius Gull

Online Theses and Dissertations

New evidence of active foraging by eastern copperheads, Agkistrodon contortrix, contradicts its description as an envenomation-reliant ambush predator. Evidence of active foraging through non-strike induced chemosensory searching (NSICS) was previously found in cottonmouths (A. piscivorus) but could not be replicated with A. contortrix in later experiments. I observed foraging methods similar to non-strike induced chemoreception when specifically predating upon cicada nymphs during seasonal emergences. I hypothesized that A. contortrix actively forage using chemoreception without envenomation, and that tongue flick rates would be higher during foraging behaviors than during non-predatory or resting behaviors. Behavior of twelve A. contortrix were filmed at …


Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky, Adam Carter Jan 2015

Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky, Adam Carter

Online Theses and Dissertations

The fate of pen-raised bobwhite quail (Colinus virginianus) released onto two farms (Site 1 and 2) and a reclaimed coal surface mine (Site 3) in south-central Kentucky during the summers of 2008 and 2009 was assessed. Of the 57 bobwhite quail radio-tagged and released in this study, the fate of 26 (45%) was unknown because the telemetry signal was lost and the birds could not be located. Within 34 days after release, mortality of the remaining 31 radio-tagged birds was 100%. Raptors, coyotes, and mesomammal predators were responsible for most (84%) of the identified quail mortality; accounting for the deaths …
