What similar features come to your mind when asked about this? Is it pigmented skin? The pneumatic bones? Giving birth? Or homeothermy?
You probably read a questionnaire that gives you these options to choose from. Do you know the answer? If not, we will give it to you and explain the topic further.
Avians do not have pigmented skin and only lay eggs. Furthermore, pneumatic bones are unique to birds for their flight adaptation. The obvious answer is homeothermy or being warm-blooded.
Birds and mammals are both warm-blooded (homeothermic). Homeothermy is the ability to maintain an internal body temperature within a certain range, despite external conditions. Warm-blooded animals or homeotherms regulate their metabolic process to maintain their body temperature.
In a comparison of birds and mammals, there are other similarities shared between these two, with a slight difference at a closer look.
- Vertebrates– both have backbones. Birds have hollow bones that aid in their flight.
- Four-Chambered Heart– the heart structure of both species has four chambers. Birds evolved into having the four-chambered heart to assist in their energy-consuming flight.
- Breathing Through Lungs– while both breathe air with their lungs, birds have a more complex respiratory system, making it more efficient than mammals
