As humans we really don’t think that psychologically, birds are capable of the same mental tasks that other mammals are, and much more specifically, some of them are in the rarest of company with us, they are near-sapient, just like our close relatives.
Birds have been shown in previous studies to possess a range of skills such as complex social reasoning, an ability to problem solve and some have even demonstrated the capability to craft and use tools. Both birds and mammals are warm-blooded, which means they can maintain a constant body temperature and do not need to rely on an external heat source to stay warm. This similarity lends itself to several other commonalities, such as similar caloric requirements by weight and the ability to remain active in colder temperatures. Cold-blooded animals do not have to eat as much, but they also cannot survive colder temperatures.
Birds require a lot of energy in order to fly. This also necessitates a circulatory system that is both efficient and effective, so they have evolved a four-chambered heart with two atria and two ventricles, just like mammals.
The blood of birds and mammals contains both red and white blood cells, called erythrocytes and leukocytes respectively. The red blood cells in both classes of animals contain haemoglobin. Another similarity between birds and mammals is that both classes care for their young after they’re hatched or born. Female mammals feed their young by lactating, while birds feed their young beak to beak.
