A female wood duck and ducklings in Arapahoe County, Colorado (© Robert Harding/Alamy)

【May 9 2017】We celebrate Teacher Appreciation Day (part of Teacher Appreciation Week in the US) by featuring this photo of a female wood duck out teaching her ducklings to swim. We’re guessing the swim is a treat for the downy students because wood ducks nest up in hollowed-out trees, often 10 feet or more above the water. To get down to the water and their calling mother, wood ducklings just a day old will take a leap from the nest and hope for a safe landing. And you thought algebra was a challenge.Explore breathtaking Gallery from the HuluTrip homepage over the past 5 years..
