Male Mallards Disappear
Revised from script written by Frances Wooden
That is BirdNote.
[Mallards chattering at edge of water]
Ah, Mallards at your native pond… They’re our largest dabbling duck and amongst geese, probably the most considerable species. They’re the supply of all home geese besides the Muscovy. (muss-KO-vee) There’s a feminine making herself heard… [Female Mallard quacking]
However does it appear that every one the brightly coloured male Mallards have disappeared? By now, the male duck’s want for fancy feathers to draw the females has handed. The male Mallards have molted, dropping their vivid inexperienced, reddish, black, and white feathers, and changing them with mottled brown ones. Turning into extra subdued colours for the months of summer time, helps camouflage the male geese, defending them from predators. Come fall, the Mallards will molt once more and return to the colourful dandies we bear in mind.
Within the meantime, whereas all of the Mallards appear to be brownish females, there’s one technique to distinguish males from females. Look intently on the invoice: the male’s invoice is boring yellow, whereas the feminine’s is orange marked with black.
And watch to see which duck is quacking. [More female quacking]
That’s the feminine Mallard.
Male Mallards make a extra subdued and raspy name, largely when courting or greeting, or once they really feel threatened.
