Stork and crane are both living around the water, and they are both large and medium-sized wading birds, which have the morphological characteristics of beak length, neck length and hind limb length, which are suitable for wading and predator hunting. The flying posture is both straight head and leg, slow fan and huge wings, so it is easy to confuse these two kinds of wading birds in the field.
Stork refers to the birds of storiformes, while crane refers to the birds of crane, which belong to different orders and families. In the process of long-term natural selection, stork and crane have gradually formed similar morphological characteristics because of their similar living environment and habits. However, if you carefully distinguish and compare them, you will find that there are some subtle differences in appearance and morphological characteristics between them.
