THE EFFECT OF VARIED ENRICHMENT TYPES ON SNAKE BEHAVIOR

Area of Science:

• Zoology
• Animal Behavior
• Herpetology

Background:

• Environmental enrichment is crucial for animal welfare, yet reptilian enrichment is understudied compared to mammals and birds.
• Zoological institutions are increasingly implementing reptile enrichment, but behavioral efficacy studies are often lacking.
• Assessing behavioral responses to enrichment is vital for understanding its utility and effectiveness.

Purpose of the Study:

• To investigate the behavioral responses of snakes to different types of environmental enrichment.
• To determine the efficacy of specific enrichment types in improving reptile welfare.
• To identify desirable and undesirable behaviors in captive snakes.

Main Methods:

• Eighteen snakes from two families (Colubridae, Pythonidae) were studied.
• Four enrichment types were introduced: Humid Hide, Olfactory, Climbing, and Suspended Hide.
• Behavioral responses were recorded for two hours post-introduction, with baseline recordings for comparison.

Main Results:

• Desirable behaviors included tongue flicking, climbing, hiding, and utilizing non-enrichment items. Undesirable behavior was interacting with transparent boundaries.
• Changes in climbing and tongue flicking were observed with enrichment, though not statistically significant.
• Some snakes exhibited reduced undesirable behaviors, indicating potential welfare improvements.

Conclusions:

• Captive snakes respond to environmental enrichment, with observed increases in certain behaviors.
• Enrichment may lead to reduced undesirable behaviors, suggesting improved welfare.
• Further research is needed to generalize these findings to other reptile species.
