NOTES: (Cross reference to Catalog #: 49069; Number of Animals and Sex: ?nestlings unknown sex, 2 adults unknown sex; Species Sound: infrequent; Breeding Status: breeding; Behavioral Context: several feeding passes made by 2 adults. calls by adults were made sometimes when both parents arrived at nest hole simultaneously, sometimes in alarm at my presence. nestlings are heard; General Climate: cyclic wet-dry; General Habitat: quaking aspen grove; Temperature: 4-21¡C; Filtering: yes) LNS #49069 for reference.
BNA" Begging calls of nestlings are heard as well as several possible "Kweek Calls" from adults. Some tapping is also heard. CZ 24/02/2004.
[This represents primarily Begging Calls by the nestlings (the "peeps" of BNA, said to be given by roughly two-week old nestlings; see also LNS #106545 and Figure 6E of BNA), both during and following a feeding pass by one or both of the parents (occurring at 0:59). As far as I can determine, the only calls given by the adult(s) are what appear to be two Wad Calls (0:07, 0:085) and a single, three-noted Double Call (0:14), the latter given by a bird in the distance. Quality unchanged (2-3 - maybe reaching 2 during the food pass) - CAM - 20 April 2005]
