Goatsuckers (Caprimulgiformes) have eyeshine owing to the presence of a tapetum lucidum. Eyes of nighthawks Chordeiles minor, poor-wills Phalaeoptilus nattallii, pauraques Nyctidromus albicollis, and a chuck-will's-widow Caprimulgus carolinensis were examined. Rods, single and double cones were present; the cones contained oil droplets. A white diffusely reflecting tapetum was observed in dark-adapted eyes of poor-wills; it was localized in the pigment epithelium of the dorsal and posterior fundus. Processes of the pigment epithelium contained numerous tapetal spheres, about 0.5 $\mu $m in diameter. The pigment epithelium also contained phagosomes and melanosomes. The tapetum is a lipid type, the reflecting material is removed by lipid solvent and coloured by lipid stains.
