Natural habitat of Gouldian Finch

Habitat

Initially Gouldian Finch was established in most of the northern part of Queensland to northern Western Australia.

Currently it distributed across Northern Australia, from King Sound east through Kimberley, southeast of the Gulf of Carpentaria region Leichhardt River, to the east (more spread) across Queensland to the northeast near Charlers Towers. While still a wide expanse, is a rare species. It has declined significantly in northern Queensland and southern Gulf of Carpentaria, the main reasons for the decrease mites air sacs, predators, intensive grazing and widespread fires and burning grass.
It is difficult to determine the absolute size of the adult population Gouldian Finch in the Northern Territory of Australia, but it is estimated that the population is less than 2,500 adult specimens at the beginning of the breeding season, however there are more optimistic estimates have indicated that the adult population can range over 10,000 copies.

In addition to the reasons indicated above and determine its stability, must be added:

1.- The sex ratio of adults is strongly deviated to males.
2.- The genetic incompatibility between different forms of color, which can lead to very high failure rates in the descendants (between 40% and 80% of the pups die in the first three months in experiments in captivity).

For all the above reasons, since 2013 the International Union for Conservation of Nature (IUCN) it was considered that the Gouldian finch is a near threatened species, so the ranks in the category NT (Near Threatened) Red List of Threatened Species IUCN.

threatened species


Black-headed specimens are more common (75% of the population) that specimens of red head and orange head specimens are very rare (one in several thousand).

Lifestyle

He lives in the woods covered with grass.The nature of their habitat can be described as a vast plain with a landscape slightly wooded acacias and eucalyptus. They are covered dry grass plains with scattered trees, often near water or in high shrubs or other vegetation along rivers, streams and water. Always living in an environment with a permanent presence of water.

The Diamond Gould is a sedentary species and partially migratory, with regular movement to the south during the rainy season (November to April) and migrate north in the southern winter (May to October) for food. In The wet season moves by forests and scrub with spinifex.
They are highly sociable among them and usually go in small groups or herds, occasionally in large flocks when not breeding. He is very active during the day and often basks. It usually is shy and reserved. Often avoids human presence.

It feeds on tall grasses and bushes (rarely eats soil grains) and seeds, especially sorghum. With the heat and humidity, these herbs grow quickly and fill with mature seeds. In the rainy season chasing and eat flying insects, termites, beetles and arachnids, constituting an important part of the diet of the Gouldian finch during the breeding season.

In nature, lifestyle Gouldian finch is determined by the supply of seeds available to you. Not only are different grass species and amounts thereof which fluctuate throughout the year, but also to changes in the quality of seeds.

In the humid rainy season (November to April) there is an abundance of mature grasses. In the dry season (May-October) seeds have matured, they fall into the ground and are hard to find. In this season of food shortages leave the breeding areas looking for food elsewhere.
Molting takes place over a short period immediately after the breeding season is over, but there is still plenty of food and good quality.

 

Weather conditions

Northern Australia and in particular the area where he lives Gouldian finchhas a tropical climate. This means that there are no four seasons as we know them here in Europe. Stations in the tropical, subtropical part of Australia consists of a dry season and a wet season.
The temperature and humidity in these areas and throughout the year are high. Tropical rain falls from November to April.
The daytime temperatures range between 35 ° C and 40 ° C and at night between 20 ° C and 25 ° C. Humidity fluctuates throughout the day and can vary between 40% and 70%.
