"Kek" calls slightly different timbre than CLRA, which is typically higher, more nasal. Not certain these two species can be safely separated by "kek" notes, however, as there is considerable variation, and maybe overlap.
观察细节
In tall grass alongside flooded ditch along CR 6 about 75 yards from intersection with CR 43. Called and then responded to playback with series of "kek-kek-kek-kek" notes, slightly more metallic and lower than CLRA. Then two series of descending grunts, more hollow and deeper than CLRA. Also produced a soft throaty flutter sound, which I have never heard on any recording. Back and scapular feathers showed very BLACKISH centers with Tawny or gold edges. Wing coverts reddish, belly darker/blacker than CLRA. A second bird, assumed to be the female, called a soft "kack" note twice.
