About Synthliboramphus craveri (Salvadori, 1866)
Craveri's murrelet (Synthliboramphus craveri) is a small black and white auk, with a small head and a thin, sharp bill. It is closely related to Scripps's murrelet, and the two species share the distinction of being the most southerly living of all auk species. Several visible traits distinguish Craveri's murrelet from Scripps's murrelet: Craveri's has a partial neck collar, while Scripps's has none; Craveri's has dusky underwings, while Scripps's has white underwings; and the black face mask of Craveri's dips slightly further down the face than that of Scripps's. The two species can also be told apart by their calls. When sitting on water, Craveri's murrelet tends to hold its tail pointed upward, a behavior that Scripps's murrelet does not exhibit.
