Many citizens have found that in the city where we live, there are more and more birds, and even some birds nest on the windowsills of citizens' homes, which constitutes a wonderful picture of birds and human beings living in harmony.

The male adult bird of the two-horned hornbill has a large beak of 30 cm long and a large and wide helmet protrusion, the upper part of the helmet is slightly concave, and the leading edge forms two horn-like protrusions, like the big horn on the rhinoceros's nose, and like the helmet of the ancient samurai, very powerful, so it is named the double-horned hornbill.

The two-horned hornbill has a large amount of food and a very mixed diet, mainly feeding on the fruits and seeds of various tropical plants, but also eating large insects, reptiles, rodents and other animal foods. It is common to forage in trees and sometimes on the ground. The hornbill's large beak looks bulky, but it is actually both a tool and a weapon, but it is very dexterous to use, picking berries with ease, peeling nuts easily, and catching rats and insects with ease.
It mainly eats a variety of wild fruits, but also snakes, lizards, large insects, rodents and grains. Breeding habits resemble those of the crowned hornbills. Feeds and inhabits the apical canopy of primary forests.
Although this species has a wide range, it occurs at a low density and is a blocky distribution. Moderately small numbers and the potential for rapid and continuous decline within their range of distribution, are therefore classified as near-threatened. It is rare in Numbers in China and has been included in the List of Wild Animals under National Key Protection.
Clear water and blue sky, birds and flowers, and living and working in peace and contentment intuitively reflect the effectiveness of ecological construction in these years, among which the birds that continue to increase in number have become the most agile existence. The number of wild birds is increasing year by year, and the variety is significantly increasing.
