NOTES: (Cover Density: None. Water Assoc: Fjord.) Filtered - LF cutoff (CB) [At least 31 examples of the "Groan Call" of BNA (some quite distant, especially later in recording), apparently given by both members of a pair. I am not certain what the two high-pitched "peeps" are at 0:35-0:38 (possibly the "Chew" Call?) Cut duration added (as the length of the entire file). Quality unchanged (2-3) - CAM - 23 March 2005]. Other Behaviors: Establish Flock Contact. Habitat: Marine, Bay/Harbor.
