影音備註
Call notes throughout, which appear to be consistent with COGO courtship displays--light "peent" calls. The raft was made up entirely of COGO; they were quite active and appeared to be moving their heads often. Very little diving observed. At the beginning of the recording, there are some non-vocal wingbeats from several individuals taking flight.
觀察細節
Male and female courtship displays: head movement seen from both and light "peent" calls heard from males.
