NOTES: (Species Sound: Constant; Breeding Status: Not territorial, Not breeding; Sound Deliv: normal; Cover Den: med) Cut starts after white leader-spoken notes on tape. Both species were seen as they peered over top of the plant cover, or hopped onto bank of the creek; but it was difficult to know which was singing or if, we think, both were singing at once. Best recording of single bird is near end. LNS note: HPF@240Hz when it was digitized. mf 23Sept02. BNA: Apparently, song and call are heard, but I cannot figure out what is being heard. CZ 01/06/2004. [I am not sure what is represented here. Based on the voice annotation, the date, and the sounds of the birds, this appears to be subsong by various Ammodramus, but I cannot differentiate the species (A. maritimus, A. caudacutus, and A. nelsoni could all be included here, but I suspect that many, if not most, of these vocalizations are those of A. maritimus). It is also posisble that this includes elements of the Complex Whisper Song of A. caudacutus (in the strict sense), but there appear to be no "typical" songs of A. nelsoni (but subsong may be anohter matter). It is quite an interesting series. Quality changed from 3 to 2-3, 2 (but with many birds singing at once - BEST after 8:51) - CAM - 11 March 2005]. Other Behaviors: Establish Flock Contact, Social Context: Mixed. Habitat: Wetland, Marine, Salt Marsh, Creek, Riparian.
