Frigatebird
Frigatebird
Frigatebird are usually seen soaring high above the ocean or remote islands in a very distinctive silhouette, with their huge outstretched, angular wings and a forked double tail; the whole look is vaguely prehistoric. Adults of the two species that can be seen off Australia are basically black, with males having red gular patches and females usually slightly larger and with more white on the underparts. Frigatebirds apparently feed mainly on flying fish, however, they are better known for their ‘kleptoparasitic’ behavior, where they steal food from other birds. They may harass birds such as boobies, terns and gulls until they drop their catch; the frigatebird then swoops for the regurgitated mess before it hits the ocean. Frigatebirds are magnificent gliders. Their wingspan may be up to 2.3 meters, and a Frigatebird of this size may weigh less than a kilogram.

Study Tours

  • Biology of Tropical Australia

    This tour combines marine biology, botany, zoology and ecology into a full 10 day tour programme of tropical ecosystems. It is designed to take in as wide range of ecosystems as possible, going from the deeper water reefs, along the coastal beaches and mangroves, into the lowland rainforest, up into the mountain forests, and finally into the savanna woodlands and wetlands of the outback.

Plants

Fungi
Fungi actually belong to a completely different kingdom from the animals and the plants and are not particularly related to either. There are thought to be about 250,000 species of fungi in Australia, and thus they far outnumber the regular vascular plants but most of these species are too small to be noticed.

Birds

Pelicans
Pelican
Pelican
The seven species of Pelican can be found wherever there is water, all around the world. They are all huge, instantly recognizable birds, with large bills and big webbed feet. They are usually white, with additions of yellow, pink, grey and/or black. Pelicans feed mainly on fish. The bottom of the bill is extremely elastic and can carry large prey. When it is fully distended, pelicans have a larger bill than any other bird. Even though they look awkward on land, they are graceful swimmers. They are also magnificent fliers, and have been found at heights of 3000 metres. The Australian Pelican is Australia’s largest flying bird, with a wingspan of almost three and a half meters. It can be found wherever there is water all around Australia and New Guinea, being especially common around estuaries. Like many other pelicans around the world, they can become quite tame, and can be found hanging around fishing jetties and taking handouts. When not breeding, they are often nomadic, having been recorded in New Zealand when there are droughts in Australia.
 

Mammals

Dogs
The first animal to be deliberately introduced to Australia by humans was probably the dingo. This 'Australian Native Dog' is, despite common misconceptions, like all breeds of domestic dogs, merely a type of the Grey Wolf,Canis lupus.
