NOTES: A.M. NIGRESCENS. 1 ADULT(S); Sex: UNKNOWN BNA: Primary Song is heard. CZ 01/06/2004. [Fifteen examples of Primary Song, as described in BNA account. There are two different song-types here. Between 0:57 and 0:59 the bird switched from the more complex song given in the beginning of the recording to a simpler song given at the end. Both songs are similar to ones in LNS #15059, but neither are quite the same. Songs similar to the second song-type given here are also found in LNS #15062, 15063, 15065, and 15069. I believe there is a "cryptic" stop-start at 1:12. Quality changed from 2-1 to 2 (though approaching 2-1, and much better than previous recording) - CAM - 17 March 2005]. Habitat: Wetland, Marine, Salt Marsh.
