Birds 
INDO-PACIFIC Tropical Seashore

The different species of birds found on the tropical seashores of the Indian and Pacific oceans...

Family Burhinidae: Thick-knees
Recurvirostridae: Stilts & Avocets

Family Haematopodidae: Oystercatchers

Haematopus longirostris, 'Pied Oystercatcher', (Lacepede Islands, Australia).

Haematopus fuliginosus, 'Sooty Oystercatcher', (Lacepede Islands, Australia).

Family Charadriidae: Plovers, Dotterels

Charadrius ruficapillus, 'Red-capped Plover', (Lacepede Islands, Australia).

Family Scolopacidae: Sandpipers, Snipes

Calidris ruficollis, 'Red-necked Stint', (Lacepede Islands, Australia).

Arenaria interpres, 'Ruddy Turnstone', (Lacepede Islands, Australia). Widespread throughout most of the coasts of the world.

Family Dromadidae: Crab Plover

Family Laridae: Terns and Gulls

Terns usually breed in pairs that are monogamous for the season.

Sterna sumatrana, 'Black-naped Tern'.

Thalasseus bengalensis, 'Lesser Crested Tern'.

Thalasseus bergii, 'Crested Tern'.

Crested Tern with egg.

Hydroprogne caspia, 'Caspian Tern'.

Onychoprion fuscatus, 'Sooty Tern', 'Wide-a-awake Tern'. 

Onychoprion anaethetus, 'Bridled Tern'. Differs from Sooty Tern by having duller darker back (but not as light as the 'Grey-backed Tern').

Gygis alba, 'White Tern'. Sometimes called 'Fairy Tern. Stunning all white tern with sharp bill and large black eyes. Mostly found on very remote oceanic islands.

White Terns nest on branches. Their single egg balances precariously on a beach tree branch with no nesting material. The small but pugnacious chick follows.

Annous, 'Noddies'

Noddys are terns with the colours reversed; instead of being white with a dark cap, they are dark with a light cap. They have stronger feet and legs, and broader wings than many other terns. These broader, gull-like wings are used to glide more than other terns. Unlike most other terns, rather than diving into the water to catch prey, they skim through the surface of the water and, like gulls, they are often seen sitting on the surface of the water. When resting from feeding and flying, they have been recorded to perch on sea turtles and even pelicans.

Although these birds often 'nod' to let the salt seep from glands near their eyes, this is not the source of the name; the name 'noddy' alludes to the naivety of the bird, making it easy to catch them.

Tribe Larini: ‘Gulls’

Gulls are similar in many ways to their close relatives the terns, but differ in the fact that they have heavier bodies and are less aerial. Generally, adult gulls are coloured in whites and greys, with patches of blacks for contrast. As in some other types of seabird, blood brightens the bill and the legs in many species of breeding adults. They are much more common in the temperate seas of the world than in the tropics. Gulls are of course mainly associated with the oceans, but they are not found too far out to sea, and they are usually a good indicator of nearby land.

Larus novaehollandiae,  ‘Silver Gull’. Slim handsome gull with light grey upperparts, snow white head underparts. Breeding adults have bright red bill and legs. This is the common gull in Australasia, and often just referred to as ‘seagull’. It is taken for granted as has increased in urban areas, and even considered a nuisance. It is less common on tropical seashores, where it scavenges around sea bird breeding colonies, and is one of the biggest predators the nesting birds have to deal with, as it strides around cracking and eating unhatched eggs or preying on chicks by standing behind them and pecking through their heads.

Family Phaethonitidae, Tropicbirds

White-tailed Tropicbird chick.

Family Procellariidae: Petrels & Shearwaters

Pterodroma ultima, 'Murphy's Petrel'. Mostly all dark grey, often has a 'dirty' white face. Mostly breeds on remote Ducie Atoll in the Pitcairn group, eastern Pacific. These birds are thought to be one of the most far-ranging foraging seabirds in the world.

Family Fregatidae: Frigatebirds

Lesser Frigatebird growing chick with adult (chick on left).

Family Sulidae, Boobies

Sula sula, 'Red-footed Booby'.

Sula leucogaster, 'Brown Booby', in flight.

With it's fluff, the growing chick of the Brown Booby quickly appears larger than the parent.

Brown Booby large growing chick. As the chicks grow, they are left by the parents for longer and longer time periods.

Family Phalacrocoracidae: Cormorants

Phalacrocorax varius, 'Pied Cormorant'.

Family Pelecanidae: Pelicans

Pelecanus conspicillatus, 'Australian Pelican'.

Family Ardeidae: Herons, Egrets, Bitterns

Egretta sacra, 'Eastern Reef Egret'.

 Eastern Reef Egret, in flight.

Butorides striata,, 'Mangrove/Striated Heron'.

Family Accipitridae: Hawks, Kites, Eagles

Haliaeetus leucogaster, 'White-bellied Sea-eagle'. Large bird of prey found along tropical shores of Australasia and Asia.
