Finches need room to fly in their cages. The finch owner should make sure that the finch cage is large enough to allow the finches plenty of room for flying. A finch cage should be wider than it is tall and provide ample room for flying from one perch to another.
Snakes belong to the animal class reptiles. This group also includes crocodiles, lizards, and turtles. Reptiles are cold-blooded animals that raise their body temperature by lying in the sun or lower it by crawling into the shade. Their body temperature changes to the temperature of its surroundings.
Temperature Regulation in Ectotherms. In addition to snakes and lizards, other reptiles are ectothermic, including turtles and crocodiles. Ectothermic classes include amphibians -- frogs, toads, salamanders -- and most fish and invertebrates. These animals regulate body temperature behaviorally. One strategy snakes and lizards use to acquire heat is sunning. They find a sunny spot to bask in and absorb heat from the sun. Warm rocks or other surfaces also provide heat. They cool down by burrowing, exposing themselves to the wind or finding shade.
