PREDATION ON ADULT LONG-TOED SALAMANDERS AND A NORTHERN RED-LEGGED FROG BY A BELTED KINGFISHER ON VANCOUVER ISLAND, BRITISH COLUMBIA: A REVIEW OF DEFENSIVE STRATEGY ADAPTATIONS
2022
Overview
A case of predation by a Belted Kingfisher (Megaceryle alcyon) on adult Long-toed Salamanders (Ambystoma macrodactylum) and a Northern Red-legged Frog (Rana aurora) is reported. This general note provides a description of the predation events with photographs of the amphibians being devoured. Additional photographs showing scars in long-toed salamanders are presented and considered in review of types of predatory attacks and defensive strategies. A literature review was completed to identify reported cases of predation on these two amphibian species. We discuss what is known about their anti-predator defensive strategies and what species are involved in the ecological and evolutionary dynamics at play. Traits exhibited by these amphibians are discussed as anti-predator adaptations that include warning colorations, defensive postures, tail dropping, crypsis, and glandular skin secretions that can be adhesive, unpalatable, or toxic. A potentially significant role of avian predators is considered in light of the evidence presented.
