Hooded Merganser Ducklings On The Water

It’s hard to picture a duck flying straight into a cavity in a tree, but there are several species of waterfowl that do just that in order to incubate their eggs in a relatively safe location.  The female Hooded Merganser selects a nesting site in a living or dead tree cavity or in a handmade nest box. Once mating and egg-laying has occurred, the male disappears, leaving his mate to raise and care for their offspring.

Within 24 hours of her eggs hatching, the female calls to her young from the cavity opening or from the water below, encouraging them to leap up to the opening and hurl themselves out into the world. The entire brood departs the nest within a couple of minutes. As soon as they hit the water, the precocial young ducks are swimming, diving and feeding on water boatmen, backswimmers, diving beetles and other aquatic invertebrates.
