Oviparous animals are female animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive.
Crimson Finches have always been one of the rarer kept Australian finches, even more so, since the end of wild-trapped birds. They have a bad reputation for being aggressive, and the fact that they are reasonably expensive, could be a couple of reasons why they are not commonly kept.
Description
There are two types of Crimson Finches, the more common black-bellied and much less kept and expensive white-bellied race. The crown is dark brown, back and wings paler brown washed red, tail long scarlet above, black below, cheeks and whole of under parts deep crimson, spotted white on flanks, centre of belly black, beak red. Hens are duller, with black beaks. They are an elegant upright bird that range from 120-140mm long.
Distribution
The black bellied or more common blood finch is found along the coastal areas from tropical north stretching inland in some areas. The white-bellied species is found in Cape York Peninsular up into New Guinea. In their natural ranges, Crimsons can be found living amongst cane and long grasses growing along watercourses. They also frequent Pandanus country, where they often build their nests amongst these palms.
Crimson Finches, like Gouldians can suffer badly in miserable weather, keeping this in mind an aviary suitable for Crimsons should afford them a reasonable amount of protection from inclement weather. They will live and breed in a box type aviary, but look and do much better in a well planted flight aviary with facilities to bathe, as they love nothing better. Crimsons have a bad reputation for being aggressive, but this is not true of every pair, and many will mix quite well.
Appearance
The crimson finch is a relatively small-sized bird. It is about 13 cm in length and weighs just 13g (0.46 oz). Standout features include a bright crimson color, long tail, and white specks that run across the sides of its body. There are also shades of grey around the neck area. This species is sexually dimorphic as the females are slightly paler in color. However, the same plumage is observed for both sexes.
A difference between males and females is that males have longer tails and bills. In addition, they are larger and heavier. Three weeks after fledging, crimson finches moult into adult plumage. The moult is only partial as juvenile greater primary coverts are preserved.

Geography
Countries
Biogeographical realms
Crimson finches are mainly distributed across Northern Australia with some residing in New Guinea. They are common in the Kimberley (Northwest) region but less widespread in the Queensland (Northeast) area.
Crimson finches’ preferred habitats are areas with tall, dense grasses. They typically reside near wetlands (riparian vegetation) that have an abundance of Pandanus trees. For nesting, they utilize shrubs and dry brush to establish nests at the base of Pandanus trees. Nests are also commonly established within hollow tree limbs.

Habits and Lifestyle
Crimson finches are renowned for their aggressive behavior; hence the nicknames “blood finch” and “killer finch”. Males are aggressive towards birds of the same species as well as different species. In any case, there is no consideration of age, coloration, or body size. Aggressive encounters are largely held on an individual basis and thus vary. Female crimson finches also exhibit similar aggressive behavior towards intruders if they are the primary defenders of a nest. However, little is known about female aggression.
For breeding, crimson finches’ primary mating system is monogamy. There are about 4 to 5 breeding pairs per 100 meters. They are known to be non-territorial and establish nests in close proximity to other birds’ nests. They primarily nest in areas that are centrally located to riparian vegetation and rivers. Unlike other southern passerines that lay small clutches, crimson finches have extremely large clutch sizes. This deviance could be explained by high rates of nest predation by reptiles, which use their olfactory sense to find nests.
For feeding, crimson finches primarily feed on seeds of grasses. One example is Xerochloa imberbis, a type of rice grass. They also feed on insects.
Crimson finches have high survival rates (70-96%). They can live up to 5 years and beyond.
