NOTES: "This double note was new to me. Calling from a tall spar overlooking a swampy backwater of the river. Also wind, water lap on boat. Credit CAGSL where feasible."
[This represents either the two-syllable, "conk-ee" call of BNA or another vocalization not described in this account. Note also that the second part of this call is similar, both structurally and in frequency, to the "downslurred" whistle pictured in Figure 2C of the BNA account. Quality added (2, 2-3 - the BEST three calls being between 0:20 and 0:28) - CAM - 19 January 2005]
