%X Sodium and potassium concentrations were analysed in the plasma and tears of three species of Anatidae. While sodium was concentrated only slightly in tears, potassium tear: plasma ratios ranged from 4 : 1 to 15 : 1, indicating that tears serve as an excretory route for potassium in these species.
