Urohidrosis
Cooling mechanism in birds
Urohidrosis (sometimes misspelled "urohydrosis"[1]) is the habit in some birds of defecating onto the scaly portions of the legs as a cooling mechanism, using evaporative cooling of the fluids. Birds' droppings consist of both feces and urine, which are excreted together through the cloaca.
