Hooded Merganser Ducklings

After selecting a nest site in a dead or living tree cavity (or man-made nest box), the female merganser builds her nest, lays eggs and incubates them for roughly a month. When incubation starts, the male abandons the female, so that all the care the young receive for their first two months is also up to her. The down-covered ducklings remain in the nest for 24 hours, after which they jump out of their nest cavity down into the water in response to their mother calling to them from below.
