The suborder Lari is the part of the order Charadriiformes which includes the gulls, terns, skuas and skimmers, with the waders and snipes making up the rest of the order. Following recent research, the auks are now placed into the Lari too; the Glareolidae might constitute a distinct suborder. Sometimes, the buttonquails are also placed here, but the molecular data and fossil record rather suggests them be a quite basal offshoot along with the snipe-like and aberrant waders.(Paton et al., 2003; Thomas et al., 2004; Paton & Baker, 2006).
