In Kentucky, at the periphery of the species' range, Siren intermedia (Lesser Siren) is a species of greatest conservation need. We monitored Lesser Sirens in a western Kentucky wetland complex from July 2018 to May 2019. Using funnel traps, we captured 60 Lesser Sirens and recaptured 2 individuals. Activity was greatest in July, and lowest October-January. Three Passive Integrated Transponder (PIT) telemetry surveys detected 7 PIT-tagged individuals; 1 Lesser Siren moved 36.9 m over 8 months. Capture success increased with warmer minimum water temperature. Body size upon first capture was unrelated to the microenvironment of the trap location. We recommend monitoring programs in western Kentucky concentrate funnel trapping in warm weather and use PIT telemetry to study movements.
