Red-breasted Mergansers show up in the Madison lakes each spring so we get to see them before they continue on their way to their breeding grounds in Canada. These funny little diving ducks have a punk rocker hair style.
According to the Cornell Lab of Ornithology, “Red-breasted Mergansers need to eat 15 to 20 fish per day, which researchers suggest means they need to dive underwater 250–300 times per day or forage for 4–5 hours to meet their energy needs.”
