What a Beak ! (Lesser Flamengo, Phoenicopterus minor) EOS 40D, 400mm f5,6 Pairi Daiza, Belgium (2011)
Flamingos filter-feed on brine shrimp and blue-green algae. Their beaks are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae which line the mandibles, and the large rough-surfaced tongue.
