Range:
This species is found in the south-western United States and Mexico, from Nebraska to northern California and south to Oaxaca in southern Mexico.

Size:
These birds are 13-15 cm long and weigh 15-23 g.

Habitat:
The rufous-crowned sparrow is found in arid and rocky open areas, including dry grasslands and dry scrublands with scattered trees. They are also found to a lesser extent in pine and oak forests. They are present from sea level up to an altitude of 3.000 m.

Breeding:
These birds are monogamous and pair bonds can remain over several years. They breed in March-August. The nest is a simple cup made of dry grass barks, twigs and hair, placed in a shallow concavity on the ground made by the birds. The female lays 2-5 bluish-white eggs, which she incubates alone for 11-13 days. The chicks are fed by both parents and fledge 8-9 days after hatching, but continue to receive food from the parents for some time after fledging.

(Photo from Serinus Africanos)

Common name:
rufous-backed bunting (en); escrevedeira-de-dorso-ruivo (pt); bruant de Jankowski (fr); escribano de Jankowski (es); Jankowskiammer (de)

Taxonomy:
Order Passeriformes
Family Emberizidae

Range:
This species is found in north-eastern China, in the provinces of Heilongjiand and Julin, in extreme north-eastern North Korea and marginally across the border into Russia.

Size:
These birds are 16 cm long.

Habitat:
The rufous-backed bunting is mostly found in temperate grasslands with scattered scrubs and small trees, and to a lesser extent in scrublands.

Diet:
They feed on the ground, eating the seeds of native grasses and scrubs.

Breeding:
Rufous-backed buntings breed in April-July. The nest is placed on the ground, near the base of a small tree or scrub. It is made of leaves and grasses and lined with hair. The female lays 4-7 greyish white eggs with purplish markings, which she incubates alone for 11-14 days. The chicks fledge 10-13 days after hatching.

Conservation:
IUCN status - EN (Endangered)
This species has a relatively large breeding range, but the global population is estimated at just 250-1.000 individuals. Although accurate population surveys are lacking, there are reports of extremely rapid declines in many locations where the species was formerly abundant, suggesting a very rapid population decline of 50-80% in recent years. The main cause for this decline is habitats loss through the conversion of natural habitats for agriculture and pasture and possibly also forestry. Disturbance by humans and grazing cattle also cause low reproductive success. Fires and predation by snakes, rats and Amur falcons Falco amurensis may also have a negative impact on this endangered species.

Corn bunting

Miliaria calandra

Common name:
corn bunting (en); trigueirão (pt); bruant proyer (fr); triguero (es); grauammer (de)

Taxonomy:
Order Passeriformes
Family Emberizidae

Range:
These birds are mostly found in Europe, from Scotland and Denmark south to Portugal, Spain and Italy, and east to Poland, the Ukraine and Turkey. They are also found in the Canary islands, in north-western Africa from Morocco to Tunisia and in central Asia from southern Kazakhstan to Afghanistan. The corn bunting is mostly resident but some population migrate south to winter in Lybia, Egypt and the Arabian Peninsula.

Size:
These birds are 16-19 cm long and have a wingspan of 27-30 cm. They weigh 35-60 g.

Habitat:
Corn buntings are found in temperate grasslands and pastures, steppes and also arable land and mixed farmland. They avoid forested areas. This species is found from sea level up to an altitude of 500 m.

Diet:
They are primarily granivorous, taking grass seeds and agricultural grain, but they also eat other plant materials and will hunt insects to feed their young during the breeding season.

Breeding:
Corn buntings breed in February-July. They are polygynous, with each male mating with up to 18 females during the course of a breeding season. Each female builds its nest, a shallow depression on the ground, lined with dried grasses. There she lays 2-6 reddish eggs with large brown stains, which she incubates alone for 10-14 days. The male may sometimes help feed the chicks who fledge 9-12 days after hatching. 

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population estimated at 30-130 million individuals. In Europe, where 50-75% of the population is found, the corn bunting has been declining at a moderate rate since the 1980s. This decline is particularly serious in north-western Europe, but it is also taking place in central Europe and is believed to be caused by changing agricultural practices and climate change. Extensive use of pesticides has reduced the numbers of arable weed species, an important food source for the adults, and insects, vital for rearing chicks.

Family Emberizidae

Range:
This species is found across much of sub-Saharan Africa, from Senegal to Ethiopia, through the D.R. Congo, Tanzania, Zambia, Angola and Malawi and down to South Africa.

Size:
These birds are 16,5-18 cm long and weigh 12-15 g.

Habitat:
Cinnamon-breasted buntings are mostly associated with rocky areas, preferring mountainsides, rocky ridges, dolerite and granite outcrops with scattered bushes and trees, bare rocky clearings in woodland, eroded stony slopes and gullies, dry watercourses and deserted borrow pits and quarries. They may also be found in areas of dry savanna, dry scrubland, dry grasslands and occasionally within urban areas.

Diet:
They forage on bare ground among rocks, eating the seeds of grasses and forbs, as well as insects such as beetles and termite alates.

Breeding:
Cinnamon-breasted buntings breed in October-June, with a peak in January-April. These monogamous, solitary nesters, build a shallow cup of grass, rootlets and fine twigs on a foundation of large twigs, neatly lined with fine grass and rootlets. The nest is typically placed in a shallow depression in the ground at the base of a grass tuft or rock, on an earthen bank, in a crevice in a small rock face or among scattered rocks in a hollow. There the female lays 2-4 eggs which are incubated by both parents for 12-14 days. The chicks are fed by both parents, fledging 14-16 days after hatching.

Conservation:
IUCN status - LC (Least concern)
This species has a very large breeding range and is described as generally fairly common and numerous. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
