The Galapagos duck or white-cheeked pintail, also known as the Galapagos teal, is a unique and notable species native to the Galapagos Islands. This small, dark-colored duck is recognized for its distinctive features, including its predominantly dark plumage with a slightly iridescent greenish sheen on the head and neck. Galapagos ducks are primarily found in freshwater habitats such as lagoons, lakes, and ponds across the islands. They are adapted to a range of environments and are known for their ability to thrive in both saltwater and freshwater conditions. The species exhibits some interesting behaviors, such as dabbling and diving for aquatic plants and invertebrates, which form the mainstay of their diet. These ducks are notable for their relatively isolated population, which has led to a limited distribution confined to the Galapagos. Their presence on the islands highlights the ecological uniqueness of the Galapagos archipelago and underscores the importance of preserving their habitat to maintain the delicate balance of the island's ecosystems.
