Most birds will preen several times a day to keep themselves healthy. The uropygial gland, or preen gland, is an essential part of preening. This gland is found near the base of the tail and produces an oily substance that contains diester waxes that help waterproof feathers and keep them flexible.While preening, birds will spread this oil to each feather.Some types of birds, including owls, pigeons, parrots and hawks, lack a uropygial gland and instead have specialized feathers that disintegrate into powder down, which serves the same purpose as preen oil.hy Preening Is Essential. Preening serves several essential purposes for birds, including: 1  Aligning feathers for optimum waterproofing and insulation. 2  Aligning feathers into the most aerodynamic shape for easier, more efficient flight. 3  Removing feather parasites and body lice that can destroy feathers or carry disease.
