Indeed, many of them do not go near land except to breed. Then they usually repair to small lonely islands often with bold precipitous shores. Ocean birds are readily divisible into four families. The first is made up of the 25 Storm-Petrels; the second of the 75 Petrels, Shearwaters, Fulmars, and Dove-Petrels; the third family comprises only the three small southern Diving-Petrels; while the fourth contains the nineteen noble Albatrosses. Though Storm-Petrels and Petrels of various kinds may be seen in the Northern Hemisphere, yet the Southern Hemisphere, with its enormous expanse of water, is the headquarters of these birds. The dainty, tiny Storm-Petrels, fearlessly tripping over the mountain billows in times of great danger to the sailor, were considered birds of ill-omen. Their peculiar flight possibly helped this idea. Gould closely studied them and other ocean birds during his voyages on sailing ships. He describes them as "fluttering over the glassy surface of the ocean during calms with an easy butterfly-like motion of the wings, and buffeting and breasting with equal vigor the crests of the loftiest waves of the storm; at one moment descending into their deep troughs, and, at the next, rising with the utmost alertness to their highest point, apparently from an impulse communicated as much by striking the surface of the water with its webbed feet as by the action of the wings." This habit of "walking" on the sea is said to be responsible for the name "Petrel," which is associated with Saint Peter, who, of old, walked on the waters. Sailors call them Mother Carey's Chickens. The largest Australian Storm-Petrel is the Whitefaced Storm-Petrel, whose scientific name, _Pelagodroma_, means "open sea wanderer." It has been recorded even from the North Atlantic and Britain. Many thousands of these birds still nest on Mud Island, a sandbank just inside Port Phillip Heads. The presence there of a true ocean wanderer is a valuable piece of evidence to support the geographer in his claim that Port Phillip Bay once had a wide opening, which has been almost closed by the drift of sand across its mouth. The Storm-Petrels have probably nested there for many, many centuries. Long may they continue to do so! They hurt no one, and they are a feature of interest to all interested in the flora and fauna of Australia, and to natural history students and Nature-lovers in general.
