Taxonomy:
Order Passeriformes
Family Passeridae

Range:
This species is found from Tibet, northern Nepal and extreme northern India into central and northern China as far as Inner Mongolia and Ningxia.

Size:
These birds are 17-17,5 cm long and weigh 30-55 g.

Habitat:
The white-rumped snowfinch is mostly found in barren rocky areas with cliffs, also using high-altitude meadows up to the snow line and bogs and swamps. They occur at altitudes of 3.800-5.500 m.

Diet:
During the breeding season they feed mainly on insects, including larval and adult beetles, wasps, flies and caterpillars. Outside the breeding season they eat mostly seeds, also taking scraps at ski resorts.

Breeding:
White-rumped snowfinches breed in April-August. They are socially monogamous and can breed either in solitary pairs or in small, loose colonies of 2-6 pairs, each nesting in a cup built by the female using of grass stems, and placed inside a pika Ochotona curzionae burrow. The female lays 2-6 white eggs, which she incubates alone for 9-15 days. The chicks are fed by both parents and fledge 18-24 days after hatching, but continue to receive food from the parents for another 2-3 weeks. Each pair can raise 2 broods per season.

House sparrow

Passer domesticus

(Photo from Wikipedia)

Common name:
house sparrow (en); pardal-doméstico (pt); moineau domestique (fr); gorrión común (es); haussperling (de)

Taxonomy:
Order Passeriformes
Family Passeridae

Range:
The house sparrow originates from Eurasia and northern Africa, but has been introduced to most of the world. It is only absent from northern Canada, Alaska and Greenland, central Africa between the Sahara desert and D.R. Congo, western Australia, southern China and south-east Asia and north-eastern Russia. It is also absent from Antarctica.

Size:
These birds are 14-17 cm long and have a wingspan of 19-25 cm. They weigh 25-32 g.

Habitat:
The house sparrow is closely associated with human settlements and buildings, from the largest urban areas to human structures in remote rural areas. It can also be found in a wide range of habitats, including arable and irrigated land, pastures, rural gardens, temperate and tropical forests, grasslands, scrublands and wetlands, but always near human dwellings. They occur from sea level up to an altitude of 4.500 m.

Diet:
They mainly eat grains and seeds, including corn, oats, wheat, rice and sorghum, as well as the seeds of wild grasses, but also rely heavily on food discarded by humans and livestock feed. They also hunt some insects, especially when feeding their young.

Breeding:
House sparrow can breed all year round, varying between different parts of their worldwide range. They usually breed in small colonies, each pair nesting in a hole in a building or other human structure, filled with coarse dry vegetation and lined with feather and artificial materials such as paper and string. The female lays 1-10 white, bluish-white, or greenish-white eggs with brown or grey spots, which she mostly incubates alone for 10-14 days. The chicks are fed by both parents and fledge 12-16 days after hatching, only becoming fully independent 2 weeks later. Each pair can raise up to 4 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range and a global population estimated at over 540 million individuals. In Europe the population has declined at a moderate rate in recent decades.

Chestnut sparrow

Passer eminibey


Common name:
chestnut sparrow (en); pardal-castanho (pt); moineau d'Emin (fr); gorrión castaño (es); maronensperling (de)

Taxonomy:
Order Passeriformes
Family Passeridae

Range:
These birds are found in eastern Africa, from Darfur in southern Sudan, through Somalia, Uganda and Kenya, an into Tanzania.

Size:
This small sparrow is 10,5-11,5 cm long and has a wingspan of 17-20 cm. They weigh 12-17 g.

Habitat:
They are mostly found in dry savanna, but also in agricultural fields, inside vilages and occasionally in swamps of papyrus.

Diet:
Chestnut sparrows often forage in large, multi-specific flocks, together with queleas and other weavers. They mostly eat grass seeds and those near human habitations will also eat crumbs and other household scraps. Nestlings may sometimes be fed insects, namely small beetles.

Breeding:
The chestnut sparrow may breed all year round, following rains, and the breeding seasons of its hosts in areas where it parasitises nests. In some areas they use the nest other birds, namely weavers, while in other areas they build their nest on a tree, an untidy domed structure, made of grass and lined with feathers. Females lay 3-4 white or bluish-white eggs, which are incubated for 18-19 days. Some observations indicate that nestlings are fed by the female alone.

Conservation:
IUCN status - LC (Least concern)
Although the global population size has not been quantified, the species is described as common or locally common in most of its very large breeding range. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
