NOTES: Cover density: OPEN; ANNOUNCED COMPARISON BETWEEN MALLARD AND REDHEAD QUACKS. FEMALE(S) [I cannot make sense of announced comparison of the "quacking" calls here, all of which sound much like a Mallard to me. There are a few whistles that are from Redhead, but I cannot be sure that any of the quacks are? These calls sound much like those in LNS #59598 but very different from those in LNS #3527. CAM - 2 November 2004].
