How does the road runner survive in the desert

[From: ] [author: ] [Date: 12-09-11] [Hit: ]
The structure of a bird’s lungs allows the air to pass through in only one direction so it doesn’t mix with air that is already in the lungs. This means a greater cooling capacity as well as higher oxygen levels. Birds flutter the throat when they’re hot, flexing the hyoid bone.

how does the road runner stay cool?
were do they recieve there food and water supplies?
what specific behaviours allow them to survive in the desert.

1)Roadrunners pant to expel body heat – they breath very quickly, letting the cooler air passing through the lungs and air sacs carry heat away from the body. A bird standing with its mouth open on a hot day is probably panting. The structure of a bird’s lungs allows the air to pass through in only one direction so it doesn’t mix with air that is already in the lungs. This means a greater cooling capacity as well as higher oxygen levels. Birds flutter the throat when they’re hot, flexing the hyoid bone. This area has a generous blood supply and thus can give off a lot of heat. To avoid overheating when it is very hot, many birds will rest in the shade during the heat of the day and be more active in the early morning and evening.

2) This bird walks around rapidly, running down prey. It mainly feeds on insects, fruit and seeds with the addition of small reptiles, including snakes, small mammals, spiders, scorpions, centipedes, millipedes, small birds, their eggs, and carrion, including roadkills. It kills larger prey with a blow from the beak—hitting the base of the neck of small mammals—or by holding it in the beak and beating it against a rock. Two roadrunners sometimes attack a relatively big snake cooperatively.The desert-dwelling roadrunner uses salt glands in front of its eyes to excrete excess salt from its blood. Such glands are common in ocean-going birds that can drink seawater. The roadrunner is able to get along without drinking water if it eats food with high enough water content, but it will drink readily if water is available.

3) To warm up after a cold desert night, a roadrunner will turn its back to the sun, fluff its back feathers, and expose skin along its back. This skin is black in order to absorb more solar energy. Greater roadrunners build nests in cholla to protect themselves from predators.
