Inhaled air passes through the primary bronchus, and most enters the posterior air sacs as well as the lungs. During this passage, air that was in the posterior air sacs moves through the lungs air capillaries so that exchange takes place. During exhalation, the air in the posterior air sacs passes through the lung en route to the external environment. Again exchange goes on during exhalation.
A blackberry's main dispersal - is by animals and birds. The plant surrounds its seeds in a tasty 'flesh'. This encourages animals and birds to eat the berries. The seeds simply pass though the digestive system and are expelled along with a 'dollop' of fertiliser.
perching birds usually eat then, after 21 minutes... they poop. when they are mating, the male perching bird sticks his penis into the female bird's vigna. they may hide it with their feathers, but bird sex is really the same as human's.
Birds sometimes defecate on their legs as a cooling mechanism. The evaporation of the excrement on their legs works like sweat does in humans. This is called "Urohidrosis" or "Urohydrosis."
Yes, just like every other breathing being, birds also have preferences when it comes to food. According to science, they have particular preference towards the color of the food.
These are called aviaries.An aviary is a large field for confining birds. Contrasting cages, aviaries allow birds a superior source of revenue breathing space where they can take wing for this reason aviaries are in addition sometimes known as journey cages. Aviaries habitually enclose plants and undergrowth to reproduce an ordinary environment.

The mechanism of CARP is the regulation of the blood glucose, breathing rate, and heart.
Like all birds, the defence mechanism is to fly away.
Circulation.
Birds + incomplete mechanism
Lungs you idiots lungs
Its the breathing mechanism, consisting of the lungs and the diaphragm and intercostal muscles.
Penguins are birds and like all birds they get oxygen by breathing air.
The Southern Cassowary (like all birds) has a pulmonary system where the lungs and the mouth are all connected.
They have a tendon-locking mechanism.
Ventilators consist of a flexible breathing circuit, gas supply, heating/humidification mechanism, monitors, and alarms
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
