Looking at zebra finches in the pet store gives no indication that there are more than thirty mutations of this common bird.
Quick Tips and Information for Zebra Finches
Bird Name:
Zebra Finch
Latin Name:
Taeniopygia guttata
Status:
Least Concern
Scientific Classification:
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Passeriformes
Family: Estrildidae
Genus: Taeniopygia
Species: T. guttata
General Information:
The Zebra Finch is also known as the Chestnut-eared Finch, the Shelley, and the Spotted-sided Finch. It is common across Australia, and has become widely kept for both research and aviculture.
Physical Description:
On average, it is about 3.9 inches long and weighs close to 17 g. The Zebra Finch has black and white tear-like stripes coming down below its eyes and reddish-brown ear patches on the sides of its head. Its upperparts are grayish-brown and its flanks are chestnut colored with white spots. There are thin black and white bars on its throat and the rump is white with a barred tail. The female doesn't have the reddish-brown ear patches, the stripes on the throat, or the spotted chestnut colored flanks of the male. Juveniles are similar in appearance to the female, but have black bills instead of the orange bills found on adult males and females. The differences between the aforementioned race, T.g. castanotis, and the other, T.g. guttata, are that the latter subspecies doesn't have the fine barring of the throat and are smaller in size.
Diet:
The Zebra Finch is primarily a seedeater, but is also known to feed on fruits and insects.
Habitat:
Due to its extensive distribution, the Zebra Finch can be found in a variety of habitats. It prefers open country, including grasslands and lightly timbered areas, but also occurs on the fringes of towns and cities. It is also common near farms. T.g. castanotis ranges across Australia, with the exception of western coastal regions and the island of Tasmania. T.g. guttata exists from Lombok in the Lesser Sunda Islands of Indonesia to Sermata and the coastal areas of Australia. The Zebra Finch has also been introduced to Puerto Rico, Portugal, and the United States. Its nests are found in a variety of places, including cavities, scrubs, low trees, bushes, in termite hills, rabbit burrows, ledges of man-made structures, and even on the ground.
Reproduction:
The female lays an average clutch of 4 - 7 small white eggs. Both parents take responsibility for incubation, which lasts about 12 - 13 days. The young fledge approximately 18 - 21 days after hatching.

Bird Name:
Owl Finch
Latin Name:
Taeniopygia bichenovii
Status:
Least Concern
Scientific Classification:
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Passeriformes
Family: Estrildidae
Genus: Taeniopygia
Species: T. bichenovii
General Information:
The Owl Finch is also known as the Bicheno Finch, Double-bar finch, and Clown finch. It is one of the smallest grass finches and is considered highly social, appearing in flocks of 20 - 40 birds.
Physical Description:
On average, it is around 3.5 - 4 inches in length. It has a white face encircled by a think black line. A second black line crosses its lower breast. The top of its head and its back are brownish, and its wings and tail are brown-black with white spots. The Owl Finch's breast and belly are creamy/white in color. The sexes are virtually similar in appearance, although the male may stand slightly taller. Juveniles have a more brownish hue above and less distinguished markings. There is also a subspecies of this bird, almost identical except for its black rump (as opposed to the white rump of the nominate species).
Diet:
Like other finches, the Owl Finch is a seedeater. It is also known to hunt for insects.
Habitat:
The Owl Finch occurs across northern and eastern Australia. It can be found on savannahs, tropical (lowland) grasslands, shrublands, open woodlands, and along the forest edge. The Owl Finch is also known to venture into gardens, sugarcane fields, and other cultivated areas. It builds its nest in grass, bushes, or low trees.
Reproduction:
In eastern Australia, breeding season is mainly during spring and autumn. In northern Australia, breeding occurs during the second half of the rainy season, but may happen later. Males typically sing during the breeding season. An average clutch size is generally 3 - 6 eggs, with 4 -5 being most common. Incubation lasts about 12 days, and hatchlings fledge at about 22 - 26 days of age. The Owl Finch is known to hybridize with a number of other finches, including the Zebra Finch, Long-tailed Grass Finch, Yellow-rumped Finch, and Masked Finch.
