There is a notch near the tip of the upper beak; the cleft in the mouth is extremely deep and the beak is underdeveloped.

There is a broad black band on the headrest, which extends to both sides and is connected to the black eye stripes, forming a black band around the top of the head, which is very eye-catching on the golden head. The occipital part of similar species of golden oriole is not black, and the black eye stripes do not extend to the occipital part. The distribution areas of the two are also different, so they will not be confused in the wild. The male and female feathers are similar in color but the female's feathers are darker. Young birds have vertical stripes. The body color is gorgeous.
Mainly eats insects, but also fruits and seeds. Arboreal birds rarely move on the ground. They like to flock together and often travel in pairs among trees. The cry is sweet.

Extended information:
Birds There are more than 9,020 known species of birds in the world, and there are more than 1,400 species in my country. According to the morphological and structural characteristics of birds, they can be divided into 2 subclasses: Archaeornithiae and Modernornithes. The species of the Archaeopteryx lithographica have long been extinct, and there are only fossil specimens called Archaeopteryx lithographica, which is an intermediate type that evolved from ancient reptiles to birds.
Neornithes, also known as Neornithes, can be divided into 3 general orders: Dentognatha, Ratite, Penguin and Cytothorax***. Except for the superorder Dentognathus (such as evening birds), reptiles are more complete in morphological structure and physiological characteristics than amphibians. Therefore, they flourished for a while in the Mesozoic Era. Not only were there many species, but they also had different body shapes and lifestyles, occupying the land area. Every corner, so this geological era is also called the Age of Reptiles. The existing species are only a few remnants of those days.
