Примечания
High-pitched sharp "keek". Occasionally the wings were jerked while vocalizing. The bird kept pacing back and forth at the edge of the cattails. BNA: The vocalization heard is the common vocalization known as a 2-note, plaintive "ker-wee", however, it is given as an abbreviated 1-note "kee" or "weep" call, similar to a spring peeper, and therefore sometimes known as the "spring peeper call" . (CZ 16/02/2004) One-hundred and twenty-nine vocalizations, all of which represent the"keep" call of Kaufmann (1983). Displays and vocalizations of the Sora and the Virginia Rail. Wilson Bull. 95: 42-59), which is presumably the abbreviated "kee" or "weep" of BNA. Note, however, that, contrary to the discussion in BNA, the sharp "keep" appears NOT to be the "Spring Peeper" Call (see Kaufmann); I suspect the calls represented here were given more in an alarm context than in a mating context. (CAM - 12 April 2005). Other Behaviors: Emit Alarm, Perform Visual Display. Habitat: Freshwater, Swamp, Pond, Edge.
