The first is the mouth shape, the normal mouth shape of macaws. But this is not the only criterion to distinguish the two parrots. Many junk parrots like Azar have the same mouths. ?

Second, look at the shape of the back of the head. Parrots are smooth arcs, while macaws are protruding. Adult macaws generally begin to show up. ?

Third, look at the body shape. The standard blood parrot is short and round, while the macaw is slightly long and flat. ?

Fourth, look at the size of the body. Generally, the blood parrot is 15-20 cm, the macaw can reach more than 25 cm, and its weight can reach 1 kg. It also grows faster than the blood parrot. ?

Macaw is a variety of blood parrot. It has a sarcoma bulge on its head, and its body color is big red. Its body length is longer than that of the blood parrot, which can reach more than 30 centimeters and its life span is about 8 years. In addition, macaws are more fierce and aggressive than ordinary parrots, which is alleviated in the case of large tanks and more animals.

It can be said that the truncated nautilus is the third generation of improved species, the blood nautilus is the ancestor of the improvement of cichlids, and the Australian nautilus is also the representative species of the improvement of early cichlids, so it is often used as a comparison with the current improved cichlids. Blood parrot fish has a small body, a big head, convex eyes and an inverted A-shaped mouth, similar to a heart-shaped pattern.
