Well, he’s preening – and seemingly really enjoying it! If you follow our This Week in the Woods series, you may recall a description of this preening process from December. Ducks (and other birds) have a special gland above their tails, which produces an oil that helps waterproof plumage. This duck is reaching back to collect oil with his beak and spread it along his feathers. See the December: Week Two entry for more details – and a link to a cool video.
