These glands are found in desert and aquatic birds as salt consumption exceeds renal clearance. These supraorbital glands drain into the nostrils and account for 20% of total NaCl excretion. They are not under the control of kidneys and they hypertrophy if the birds salt intake increases.

====Avian Renal Portal System====
In birds the blood from the hindlimbs is carried directly to the kidneys. It bypasses the glomeruli and waste products in the blood are secreted directly into the tubules. This is thought to be a more efficent way to excrete uric acid and urate.
