Merops albicollis
This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green, but its face and throat are white with a black crown, eye stripe, and neckband. The underparts are pale green shading to blue on the breast. The eye is red and the beak is black. The white-throated bee-eater can reach a length of 19–21 cm, excluding the two very elongated central tail feathers, which can exceed an additional length of 12 cm. They weigh between 20 and 28 grams. Sexes are alike, except that the male has longer tail feathers. The call is similar to European bee-eater.
