Gouldian Finch

With one of the most striking plumages in the entire animal kingdom, the Gouldian finch almost looks like it was put together in patches.

The head, breast, abdomen, and back all exhibit an elegant rainbow of different colors. It’s no surprise that this species is highly sought after in the pet trade. After decades of decline, however, the Gouldian finch is now facing the prospects of an uncertain future.

3 Amazing Gouldian Finch Facts

• The standard Gouldian finch is a bird that comes in three different facial varieties. Approximately 70% to 80% have black-colored faces. Another 20% to 30% have red-colored faces. The yellow-colored Gouldian finches are the rarest of all. Only about one in 3,000 members of the species are born with this variation.
• This tropical bird prefers hot temperatures above 80 degrees Fahrenheit (or 27 degrees Celsius).
• The male’s brighter plumage and song-making ability have evolved to attract mates in the breeding season. The intensity of the colors and song might serve the purpose of signaling to the female the bird’s strength and health.

Habitat: Where to Find Them

The Gouldian finch is a bird that was once found across much of northern Australia. Now it only occurs in a few places around the Northern Territory, the Kimberley region of Western Australia, and sometimes as far east as Queensland. It prefers to live in open grasslands and plains with a nearby source of water and enough smooth-barked Eucalyptus trees in which to live. The species requires a precise mixture of grass species on which it feeds.

Gouldian Finch Nests

Several Gouldian finch pairs may share grass nests within tree hollows.

Scientific Name

The scientific name of the Gouldian finch is Erythrura gouldiae. Gouldiae is simply the Latinized name of the British ornithologist John Gould, who first categorized this finch and named it after his wife (hence the alternate name Lady Gouldian finch). The Lady Gouldian finch is sometimes placed in the genus of Erythrura with other parrotfinches or its own separate genus, Chloebia. It also belongs to the family of tropical Asian and Australian finches known as Estrildidae.

Evolution and History

The Gouldian finch is a fascinating species of bird that has captured the attention and curiosity of many scientists and enthusiasts alike. Its evolutionary history can be traced back to the Pleistocene epoch, which occurred approximately 2.6 million years ago. The fossil record reveals that these birds originated in what is now known as northern Australia, where they likely evolved from ancestral populations of grass finches.

Over time, the Gouldian finch developed distinctive physical characteristics that set it apart from other species. For example, its bright plumage, which comes in a range of colors such as red, green, yellow, and black, evolved primarily due to sexual selection pressures. Male birds with brighter feathers were more attractive to potential mates than those with duller ones; over generations, this led to an increase in the proportion of brightly colored individuals within the population.

Despite their striking appearance, Gouldian finches have faced significant challenges throughout their history. Habitat loss due to human activities like deforestation has been one major factor contributing to declines in population numbers across much of their range. Additionally, introduced predators like cats and foxes have had devastating impacts on local populations by preying on adult birds or destroying nests.

Fortunately, there are conservation efforts underway aimed at protecting these beautiful birds for future generations to enjoy!

Size, Appearance, and Behavior

The Gouldian finch exhibits a true rainbow of colors. Most birds have a red, yellow, or black “cowl” on the head, a turquoise or light green band around the shoulders, purple back and wings, and a yellow abdomen fading to white. That is in addition to several unique mutations, including a silver color. The main difference between the sexes is that the males exhibit brighter purple feathers, while the females have a paler purple breast. The male is also the only one that explicitly sings, but both sexes can produce chirps, hisses, clicking, and trills to communicate with each other. This bird measures around 5.5 inches in length and wingspan.

The Gouldian finch is a social species that gather in large flocks of hundreds outside of the breeding season. These mixed flocks also contain long-tailed finches and masked finches, both of which are members of the same taxonomical family. During the day, when the bird is most active, the dense foliage of the Eucalyptus tree provides protection from the hammering rays of the sun. They may also come down to the ground to forage.

Gouldian Finch Migration Pattern and Timing

The Gouldian finch is not migratory, per se, but these nomadic birds do wander from place to place in search of better food and water sources when one location becomes sparse and dry.

Gouldian Finch Diet

Like many other species of finch, the bird’s stout and strong beak is well-adapted for cracking open and eating seeds. They eat up to 35% of their body weight every single day.

What does the Gouldian finch eat?

The diet of the Gouldian finch consists of several different kinds of grass seeds throughout the year based on availability. Its favorite foods appear to be ripe or half-ripe sorghum seeds, which occur during the wet season, but during the dry season, it also forages on the ground for any grass seeds it can find.

Predators, Threats, and Conservation Status

Over the last few centuries, the Gouldian finch has faced numerous threats from habitat loss (especially from rampant fires), predators, herbivorous competitors, diseases, and parasites (such as mites). This species paid a heavy price for its striking colors, which make them a conspicuous and noticeable target for trappers and predators alike. Large numbers of them were trapped by humans for private use. Australia banned trapping and exportation in the 1980s, though the species continues to be bred in captivity. The IUCN Red List currently considers them to be near threatened. The Australian government lists them as endangered.

What eats the Gouldian finch?

The Gouldian finch is usually preyed upon by feral cats, hawks, and snakes. The bird is most likely to fall victim to predators within the first several weeks of life before it has become fully independent.

Reproduction, Young, and Molting

As the breeding season approaches, usually between December and April, the male finch puts on a brilliant courtship display by expanding his chest, fluffing out his feathers, and bobbing his head up and down. The female reciprocates his advances by wiping her beak.

After they pair up, the female produces one egg per day until she’s laid between four and eight of them. Both parents play a vital role in incubating the eggs and raising the young. After about two weeks of incubation, the chicks hatch from the eggs with no feathers and blue nodules at the corner of the beaks to help the parents find their mouths in the dark.

Although completely dependent on their parents for food and protection, these chicks will gain their full-flight feathers after about three to four weeks of life. At this stage, both males and females sport a duller green-gray plumage color. Only after they grow their full adult feathers between eight months and a year old will their sex become obvious, right around the time they reach sexual maturity and begin breeding. These birds live up to eight years in captivity, though many wild birds do not survive their adolescence and have a shorter lifespan.

Population

Millions of these finches once roamed across Australia. Now only 2,500 mature individuals remain in the wild, although population numbers appear to be stable. These finches rely on healthy and mature trees, so conservationists have focused their efforts on fire management and habitat maintenance.
