How do birds maintain water balance?
Subsequently, one may also ask, how do birds retain water?
Most birds drink water by filling their bill with the liquid—often from morning dew on leaves—then tilting their head back, using gravity to send the liquid into their digestive tract. But then birds must tilt their head to swallow. Swifts and swallows skim a billful of water as they fly over lakes, ponds and rivers.
Also to know, how do seabirds maintain water balance?
Seabirds have no problem drinking sea water. The salt they take in is absorbed and moves through their blood stream into a pair of salt glands above their eyes. The densely salty fluid is excreted from the nostrils and runs down grooves in the bill.
Loop of Henle, long, U-shaped portion of the tubule that conducts urine within each nephron (q.v.) of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine.
