Mud Islands
The Mud Islands reserve is located within Port Phillip, about south-west of Melbourne, Australia, lying inside Port Phillip Heads, north of Portsea and east of Queenscliff. The land area of about is made up of three low-lying islands surrounding a shallow tidal lagoon connected to the sea by three narrow channels. The shapes and configuration of the islands change over the years due to movement of sand by tidal currents. History First sighted by Europeans in 1802, the islands were originally named ''Swan Isles'' because of the large number of swans on the surrounding waters. It was not until 1836 that Lieutenants T M Symonds and H R Henry of surveyed the islands and renamed them ''Mud Islands''. Protection In 1961, the Victorian Fisheries and Wildlife Department declared the islands a sanctuary for the White-Faced Storm Petrel. In 1979, the area of the islands above high water was proclaimed a permanent reserve for the management of wildlife. It forms part of the P ...

Port Phillip
Port Phillip (Kulin languages, Kulin: ''Narm-Narm'') or Port Phillip Bay is a horsehead-shaped bay#Types, enclosed bay on the central coast of southern Victoria (Australia), Victoria, Australia. The bay opens into the Bass Strait via a short, narrow channel (geography), channel known as The Rip, and is completely surrounded by suburbs and localities (Australia), localities of Victoria's two largest cities — metropolitan Greater Melbourne in the bay's main eastern portion north of the Mornington Peninsula, and the city of Greater Geelong in the much smaller western portion (known as the Corio Bay) north of the Bellarine Peninsula. Geographically, the bay covers and the shore stretches roughly , with the volume of water around . Most of the bay is navigable, although it is extremely shallow for its size — the deepest portion is only and half the bay is shallower than . Its waters and coast are home to Pinniped, seals, whales, dolphins, corals and many kinds of seabirds and ...

Crested Tern
The greater crested tern Retrieved 28 February 2012 (''Thalasseus bergii''), also called crested tern or swift tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to the royal and lesser crested terns, but can be distinguished by its size and bill colour. The greater crested tern has grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter. Its young have a distinctive appearance, with strongly patterned grey, brown and white plumage, and rely on their parents for food for several months after they have fledged. Like all members of the genus ''Thalasseus'', the greater crested tern feeds by plunge diving for fish, usually in marine en ...

Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is the most common gull of Australia. It has been found throughout the continent, but particularly at or near coastal areas. It is smaller than the Pacific gull (''Larus pacificus''), which also lives in Australia. The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages (scientific name ''Larus argentatus'', German ''Silbermöwe'', French ''Goéland argenté'', Dutch ''zilvermeeuw''), but is a much larger, robust gull with no overlap in range. Taxonomy It has traditionally been placed in the genus ''Larus'', as is the case with many gulls, but is now placed in the genus ''Chroicocephalus''. Hartlaub's gull (''C. hartlaubii'') of South Africa was formerly sometimes considered to be subspecies of the silver gull. There are three subspecies: * ''C. n. forsteri'' ( Mathews, 1912) – north and northeast Australia, New Caledonia, Loyalty Islands * ''C. n. novaehollan ...

South Channel Fort
South Channel Fort, also known as South Channel Island, is a 0.7 ha artificial island in southern Port Phillip, Victoria, Australia, 6 km north-east of the town of Sorrento. It was part of a network of fortifications protecting the narrow entrance to Port Phillip. It is 122 m long, 76 m wide, and is 6.4 m above sea-level, and was built on a shoal, close to the main shipping channel of the bay, with 14,000 tonnes of bluestone boulders, concrete and sand. It was constructed during the 1880s as part of a defensive strategy to protect and control access by sea to Port Phillip and the cities of Melbourne and Geelong. Its principal purpose was to illuminate the main shipping channel at night, and to explode mines under attacking ships which had breached the defences at Port Phillip Heads. The fort still contains remnants of its original military equipment, including disappearing guns. Construction South Channel Fort was built with a protective ring of bluestone rocks which ...

White-faced Storm-petrel
The white-faced storm petrel (''Pelagodroma marina''), also known as white-faced petrel is a small seabird of the austral storm petrel family Oceanitidae. It is the only member of the monotypic genus ''Pelagodroma''. Description The white-faced storm petrel is in length with a wingspan. It has a pale brown to grey back, rump and wings with black flight feathers. It is white below, unlike other north Atlantic petrels, and has a white face with a black eye mask like a phalarope. Its plumage makes it one of the easier petrels to identify at sea. Behaviour The white-faced storm petrel is strictly pelagic outside the breeding season, and this, together with its often-remote breeding sites, makes this petrel a difficult bird to see from land. Only in severe storms might this species be pushed into headlands. There have been a handful of western Europe records from France, the United Kingdom and the Netherlands. It has a direct gliding flight and will patter on the water surface as i ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ...
