A 4-card field-ID dossier for the Mallard (Anas platyrhynchos), Episode 7 of 59. Covers the iconic iridescent-green-headed male with female inset, a dorsal/ventral flight-view card highlighting the diagnostic blue-purple speculum, a call card distinguishing the female's descending KWAK series from the male's soft rasp, and a four-panel look-alike comparison against American Black Duck, Mottled Duck, and Gadwall.
