[This represents almost exclusively begging calls by the nestlings, but there are examples of the "few" call described in BNA, apparently given by the adults as they left the nest (at 0:20, 1:23, 2:03, 2:05, 4:52, 5:15, 5:47 (2 - the two BEST examples of this call in this recording), and 6:07). Quality unchanged (2, 1-2 - the BEST parts are between 3:29 and 5:30) - CAM - 10 February 2005]
