Eurystomus orientalis Linnaeus, Broad-billed Roller, Oriental Dollarbird, specific habits are unknown.

Sanbao birds like to eat green scarab beetles and other beetles, but also eat locusts, longans, golden flower insects, pear tigers, lifting tail insects, stone silkworm, kowtowing insects and so on. Foraging often rotates back and forth in the air, hunting by non-stop flying, faster, after capturing insects and returning to the original branches. Tri-treasure birds rarely forage on the ground. Make a gruff "kreck..." when flying or resting on branches. "kreck."

The three-treasure bird usually lives on the dead trees in the open areas near the forest, and flies away immediately when approached, occasionally taking off to chase insects passing by, or diving down to catch insects on the ground. Flying posture like a nighthawk, strange, heavy, sometimes slow flight, long wings evenly and rhythmically swing up and down, and sometimes rush straight up, or turn straight down, circling or flapping at random, and constantly issuing a monotonous and coarse "rattle" sound. Three or two birds sometimes fly or dive together at dusk, especially during courtship. It is sometimes besieged by flocks of small birds, whose head and beak make it look like a bird of prey.

The global population size of Sanbao has not been quantified, but the species is reported to occur frequently in its range, with population estimates by country and region as follows: 100-10,000 pairs of adult birds and 50-1000 travellers in China, with less than 1000 travellers in Taiwan; There are 100-10,000 pairs of adult birds and 50-10,000 travellers in Korea; Less than 100,000 pairs of adult birds and less than 1,000 travellers in Japan; There are 100-10,000 pairs of adult birds and 50-1000 travellers in Russia.

In 806 AD (Yuan and the first year of the Tang Dynasty), the Japanese monk Master of Buddhism, the title of Konghai, returned to Japan from China, in Koye Mountain's Kumgang Feng Temple, wrote down the three treasure birds "idle forest" seven unique, for the famous poem about the Buddhist monk's three treasure birds, poetry cloud: "Idle forest sitting alone in the grass hall, the sound of the three treasure a bird. When a bird speaks, a person has a heart, and the sound of the heart is gone."
