Poephila cincta

Photo by Vladimír Motyčka (BioLib)

Common name:
black-throated finch (en); diamante-de-garganta-preta (pt); diamant à bavette (fr); diamante gorjinegro (es); gürtelgrasfunk (de)

Taxonomy:
Order Passeriformes
Family Estrildidae

Range:

This species is endemic to Queensland, Australia, where it is currently found on the Cape York Peninsula. In the past its range extended southwards into northern New South Wales.

Size:
These birds are 10-12 cm long and weigh about 15 g.

Habitat:
The black-throated finch is found in dry, grassy savannas and open forests dominated by eucalypts, paperbarks or acacias, and also uses scrublands, pastures and arable land.

Diet:
They mainly feed on the seeds of various grasses and herbs, such as such as Urochloa mosambicensis, Digitaria, Melinis repens, Chloris inflata, Dactyloctenium, Eremochloa, Paspalidium and Setaria. They also take some spiders, ants and termite alates.

Breeding:
Black-throated finches can breed all year round. They breed in colonies and the nest is built by both sexes, consisting of a round structure woven from dried grasses with tube-like entrance. It is typically placed in a fork in a tree or scrub, about 5 m above the ground. There the female lays 3-9 matte white eggs, which are incubated for 12-15 days. The chicks are fed by both parents and fledge 21-22 days after hatching, but only become fully independent 3 weeks later. Each pair raises 1-2 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has a large breeding range and is described as fairly common or locally common, but less common in the south of its range. The population is suspected to be in decline at a slow rate, owing to the clearance and degradation of its habitats, mainly due to the spread and intensification of pastoralism, changes in fire regime and increases in the density of native woody weeds in grassy savannas. Despite this, the black-throated finch in nor considered threatened at present.

Java sparrow

Padda oryzivora

Common name:
Java sparrow (en); pardal-de-Java (pt); padda de Java (fr); gorrión de Java (es); reisfink (de)


Taxonomy:
Order Passeriformes
Family Estrildidae

Range:
This species was originaly endemic to the islands of Java, Bali, and probably Madura, in Indonesia. It is a common cage bird and feral populations have been established in many parts of the world.

Size:
These birds are 14-19 cm long and weigh 30-40 g.

Habitat:
In their native range, Java sparrows are found in dry savannas, scrublands and grasslands, as well as in rural gardens, arable land, rice paddies and within urban areas. They are mostly present from sea level up to an altitude of 500 m.

Diet:
They mostly eat the seeds of grasses and other flowering plant, namely rice seeds, but also some insects.

Breeding:
Java sparrows breed in February-August within their native range. The nest is a loosely built structure of dried grass, constructed under the roofs and eaves of buildings in towns and villages, or in scrubs and treetops. The female lays 4-8 white eggs, which are incubated for 12-15 days. The chicks are fed by both parents and fledge 2-3 weeks after hatching.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively large native range, but the native population is estimated at just 1.500-7.000 individuals. There are larger introduced populations elsewhere, for instance in China or Japan. The native population is declining at a rapid rate, mostly due to the high trapping pressure for the cage bird trade. Historically, it was regarded as a rice crop-pest, and consequently persecuted, while hunting for local consumption still takes place. Other potential threats include the increased use of pesticides and competition with the ecologically similar tree sparrow Passer montanus.

They are found in grassy areas interspersed with dense understorey vegetation, often along creek lines.
Diet:
Red-browed firetails mostly feed on seeds and insects on the ground, but sometimes perches on seeding grass heads.

Breeding:
These birds breed in October-April. The nest is large and domed, with a side tunnel for an entrance. It is a rough construction of twigs and grass stems built in a dense shrub 1-2 m above the ground. There the female lays 4-6 eggs which are incubated by both parents for 14 days. The chicks are fed by both parents and fledge 22 days after hatching. Each pair may produce 2-3 broods per season.
Conservation:
IUCN status - LC (Least Concern)
This species has a large breeding range and, although the global population size has not been quantified, the species is described as common or locally common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
