Common name:
cream-coloured courser (en); corredor (pt); courvite isabelle (fr); corredor (es); rennvogel (de)

Taxonomy:
Order Charadriiformes
Family Glareolidae

Range:
This species is found around the Sahara desert, along the Mediterranean coast Africa, in Morocco and Mauritania and in some areas of the Sahel such as Mali and Sudan. Also in parts of the Canary islands and Cape Verde, and, through the Middle East, into Iran, Turkmenistan, Afghanistan, Pakistan and marginally into north-western India.

Size:
These birds are 19-24 cm long and have a wingspan of 51-57 cm. They weigh 93-156 g.

Habitat:The cream-coloured courser is found in arid, open, stony or sandy desert and semi-desert, including dry grassland and scrubland, gravel plains, gravel roads, salt flats and dune troughs. They occur from sea level up to an altitude of 800 m.

Diet:They feed mainly on adult and larval insects, including beetles, grasshopper, ants and flies, but also other invertebrates such as molluscs, spiders and isopods, and seeds.


Breeding:
Cream-coloured coursers breed in February-July. The nest is a shallow, unlined scrape on bare ground, where the female lays 2 whitish eggs with dark brown spots and mottles. The eggs are incubated by both parents for 18-19 days. The chicks leave the nest soon after hatching, but remain with their parents until fledging, about 30 days after hatching. They reach sexual maturity at 1 year of age.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range. The global population size is unknown due to recent taxonomic splits, but the overall population trend is stable, despite some populations having unknown trends.

Common name:
Cape siskin (en); canário-do-Cabo (pt); serin totta (fr); canario de El Cabo (es); Hottentottengirlitz (de)

Taxonomy:
Order Passeriformes
Family Fringillidae

Range:
This species is endemic to South Africa, only being found in the Eastern and Western Cape provinces.

Size:
These birds are 12-13 cm long and weigh 10-20 g.

Habitat:
The Cape siskin is mostly found in dry fynbos scrublands and coastal scrublands, also using clearing in dry tropical forests, fringes of succulent karoo vegetation, edges of pine plantations and village gardens.

Diet:
They feed on the seeds and buds of various grasses and scrubs, also taking flowers, nectar and some insects.

Breeding:
Cape siskins are monogamous and breed in August-December. They nest in a shallow cup of fine dry grasses and rootlets, lined with fine grass sometimes mixed with down, wool or hair. The nest is typically placed in a horizontal crevice, small depression or cavity in a rock face or tree. The female lays 3-5 eggs, which she incubates alone for about 13 days while being fed by the male. The chicks are fed by both parents and fledge about 19 days after hatching.

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

Salvin's curassow

Common name:
Salvin's curassow (en); mutum-de-ventre-branco (pt); hocco de Salvin (fr); paujil culiblanco (es); Salvinhokko (de)

Taxonomy:
Order Galliformes
Family Cracidae

Range:
This species is found in the lowlands of southern Colombia and northern Ecuador, east of the Andes.

Size:
These birds are 75-89 cm long and weigh about 3 kg.

Habitat:
The Salvin's curassow is found in terra firme primary rainforests, avoiding flooded areas. They are present from seal level up to an altitude of 600 m.

Diet:
They feed mainly on fallen fruits, also taking seeds and, to a lesser extent, leaves and insects.

Breeding:
Salvin's curassows are monogamous and the nest is made of leaves and placed at moderate height on a tree branch or vine. The female lays 2 eggs, which are incubated for 4-5 weeks.
The chicks leave the nest soon after hatching, but are fed by both parents until they learn to pick food from the ground. Each pair can raise 4 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has a large breeding range and the global population is estimated at 50.000 individuals. The Salvin's curassow suffers from heavy hunting pressure, mainly for local food consumption, and a model of Amazonian deforestation predicts the species will lose about 11% of suitable habitats in the next 3 decades. Both suggest the species may suffer a small decline in the near future.

Eyebrowed jungle-flycatchers breed in January-April. The nest is an untidy cup or ball made of small sticks, moss and leaves, usually placed on an epiphyte or spiny palm. There is no further information on the reproduction of this species.

Conservation:
IUCN status - LC (Least Concern)
This species has a relatively large breeding range and is described as fairly common or locally common. The population is suspected to be in decline owing to ongoing habitat destruction.

Diet:
They feed mainly on insects and other small arthropods, but also take snails, seeds and fruits.

Breeding:
These birds can breed all year round, but mainly in August-January. They can be either monogamous or polyandrous.

Conservation:

IUCN status -LC (Least Concern)
This species has a very large breeding range and is reported to be locally common. The population is suspected to be in decline owing to ongoing habitat loss and degradation and predation by introduced mammals.
