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.

Similarly, why do birds drink very little water? Drinking water Birds have no sweat glands, so they need less water than mammals. However, they do lose water through respiration and in their droppings. Most small birds need to drink at least twice a day to replace the lost water. Birds get the liquid they need from their food and by drinking.

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.

Do birds have a loop of Henle?

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.

Do reptiles need salt?

The need for salt excretion in reptiles (such as marine iguanas and sea turtles) and birds (such as petrels and albatrosses) reflects their having much less efficient kidneys than mammals. Unlike the skin of amphibians, that of reptiles and birds is impermeable to salt, preventing its release.
