Swallows have similar male and female feathers. The top of the head is dark brown, and the sides of the head, the back neck and the side of the neck, and the upper body, including the upper tail feather, winglet feather and inner wing feather, are dark brown. The wings and tail are dark brown-gray, and the tail feathers are short and slightly concave, almost square. Except for the middle pair and the outermost pair of tail feathers, there is a large white spot at the proximal end of other tail feathers at 1/3.

The chin, throat and upper chest are white, some chin and throat have dark brown or gray spots, the lower chest and abdomen are dark brown sand, and the wings, lower abdomen and lower tail are covered with dark smoke brown. The iris is dark brown, the mouth is black, and the color is flesh and blood. Young birds are similar to adult birds, but the upper part of young birds is dark, with broad dark brown feathers, and the waist and tail are covered with yellowish feathers. The lower body is reddish brown, and there are no brown markings on the chin and throat. ?

There are more than 20 species of domestic swallow, rock swallow, grey sand swallow, golden waist swallow and hairy foot swallow in the world, and there are 4 species in China, among which domestic swallow and golden waist swallow are more common.

I like flying on lakes, fish ponds, swamps, reservoirs, rivers and other water surfaces. Active in valleys, open areas in front of mountains or flying in the air along rivers. Perched on cliffs and dry valleys. Named subspecies are very rare in the western, northern, central and southwestern regions of China at an altitude of 1800-4600 meters.

Some northern birds overwinter in southwest China in winter, mainly flying in the air to prey on insects. Common species are scarabs, mosquitoes, wasps, flies, beetles and so on. They are used to preying on flying insects in the air.
