Scientists have also discovered that some species of birds can tell each other apart by smell.
They have almost never been observed drinking water in the wild. However, recent research reveals that some species of birds have a high number of active genes that are associated with smell.

Back to Top Barn Owls get most of the water that they need from eating their prey. Back to Top Traditionally, scientists assumed that most birds have a poor sense of smell because the area of a bird’s brain involved in smell is relatively small compared with the area found in mammals. Mammals excrete waste as urea dissolved in urine; birds excrete it as uric acid, which has a low solubility in water, and so it comes out as a white paste. Owls swallow food whole or rip it apart in their beak and swallow pieces. The white pasty excrement is uric acid, the equivalent to a mammal’s urine.

Any indigestible parts of prey such as fur and undigested bones are regurgitated as a pellet.
