Common name:
hadada ibis (en); singanga (pt); ibis hagedash (fr); ibis hadada (es); hagedasch (de)

Taxonomy:
Order Ciconiiformes
Family Threskiornithidae

Range:This species is found across most of sub-Saharan Africa, from southern Mauritania to southern Sudan and south to South Africa. It is mostly absent from Angola, Namibia and Botswana.

Size:
These birds are 65-75 cm long and have a wingspan of 90-100 cm. They weigh 1,2-1,3 kg.

Habitat:
The hadada ibis is mostly found in wooded streams and rivers, also using wet grasslands, savannas, irrigated areas, marshes, lakes and reservoirs, mangroves, coastal beaches and forest edges.

Diet:
They feed on various invertebrates, such as earthworms, crustaceans, large insects, spiders and molluscs, but also take lizards and human scraps.

Breeding:
Hadada ibises can breed all year round, varying among different parts of their range. They are monogamous, solitary nesters. The female builds the nest alone, consisting of a platform of sticks with a central bowl lined with grass, lichen, weeds, leaves and other debris. It is typically placed in the fork of an horizontal branch, or occasionally on another structure such a cliff, dam wall, telephone pole or pergola. The female lays 1-5 eggs, which are incubated by parents for 25-28 days. The chicks are fed by both parents and fledge 33-40 days after hatching, but only become fully independent about 3 weeks later.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range and is described as widespread and common. The population has probably increased in the last century due to an increase in the availability of nest sites and food from habitat modification by humans.

Taxonomy:
Order Psittaciformes
Family Psittacidae

Range:
This species is only found in West Africa, from Guinea-Bissau and southern Mali to Liberia and the Ivory Coast.

Size:
These medium-sized parrots are 28-33 cm long and weigh 275-275 g.

Habitat:
Timneh parrots is found in moist tropical forests and neighbouring savannas, also using forets clearings, gallery forests, mangroves, cultivated areas and even gardens. They are present from sea level up to an altitude of 2.200 m.

Diet:
They feed on seeds, nuts, berries and fruits, including oil-palm fruits.

Breeding:
The timneh parrot breeds in January-July. They nest in a tree hollow, typically high up on a tall tree, where the female lays 2-3 eggs. The eggs are incubated for 28-30 days and the chicks fledge 11-12 weeks after hatching.

Conservation:
IUCN status - VU (Vulnerable)
This species has a large breeding range but the global population is estimated at just 100.000-500.000 individuals. The population is estimated to decline by 30-50% over the next 5 decades, mostly due to the massive level of capture for the illegal bird trade and high levels of forest loss in parts of the range. Despite international efforts to prohibit trade, thousands of birds are likely being illegally exported every year. Deforestation is still a very serious problem within the timneh parrot range, with 77% of the original forest cover already being lost.

Range:
This species is found from Panama south to Bolivia and central and western Brazil.

Size:
These bird are 10-11 cm long and weigh 20 g.

Habitat:
The short-tailed swift is found in moist tropical forests, dry tropical forests and savannas, scrublands, second growths and plantations, often favouring areas near water. They are present from sea level up to an altitude of 1.300 m.

Diet:
They feed on flying insects, including winged ants and termite alates.

Breeding:
Short-tailed swifts nest in a shallow half-saucer made of twigs and saliva, attached to a vertical surface such as a chimney, manhole, well or a natural cave or tree cavity. The female lays 3-7 white eggs, which are incubated by both parents for 17-18 days. The chicks leave the nests 2 weeks after hatching, but remain near it, clinging to the cavity wall without flying, for another 2 weeks.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is described as common. The short-tailed swift is suspected to lose 15-17,5% of suitable habitat within its range in the near future, based on a model of Amazonian deforestation, being therefore suspected to suffer a moderate decline in the next 2 decades.

Conservation:
IUCN status - CR (Critically Endangered)
This species has a small and fragmented breeding range and a global population estimated at just 50-250 individuals. The population trend is unknown, but believed to be declining due to low productivity. The blue-crowned laughingthrush is threatened by trapping for the cage bird trade, road building and urban development, and the very small population may now be prone to the loss of genetic diversity. A number of small Special Protected Areas were established in Jiangxi Province to protect this species.

Family Icteridae

Range:
This species breeds in Mexico an the south-western United States, as far north as Nevada, Utah and Colorado. The more northern population migrate south to winter in western and southern Mexico.

Size:
These birds are 22-24 cm long and have a wingspan of 29-32 cm. They weigh 32-41 g.

Habitat:
The Scott's oriole is found in hot deserts and dry scrublands, especially in areas populated by yuccas. they are present from sea level up to an altitude of 3.000 m.

Diet:
They feed mainly on insects, such as grasshoppers, beetles, ants, bees, butterflies, caterpillars and other insect larvae. They also eat berries, cactus fruits and nectar.

Breeding:
Scott's orioles breed in April-July. They are monogamous and the nest is a slightly hanging basket of woven plant fibres stripped from dead leaves, lined with soft grasses and other plant fibres. It is placed in a small trees or scrub, mainly yuccas, usually hanging from the leaves at the crown of the tree. There the female lays 3-5 pale blue eggs with dark spots and streaks, which she incubates for 12-14 days. The chicks are fed by both parents and fledge 14 days after hatching. Each pair raises 1-2 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has a large breeding range and the global population is estimated at 1,6 million individuals. In the United States the population has undergone a small decline over the last 4 decades.

Common name:
pale-headed brush-finch (en); tico-tico-cinzento (pt); tohi grisonnant (fr); saltón cabecipálido (es); blasskopf-buschammer (de)

Taxonomy:
Order Passeriformes
Family Emberizidae

Range:
This species is endemic to southern Ecuador, only being found in the río Jubones drainage, in Azuay and Loja.

Size:
These birds are16-16,5 cm long and weigh 28,5-35 g.

Habitat:
The pale-headed brush-finch is mostly found in regenerating landslides and other steep slopes with dense scrubland interspersed with small clearings, usually in the transition between arid and humid areas. They are only present at altitudes of 1.650-1.950 m.

Diet:
They feed on a variety of invertebrates, especially caterpillars and winged insects, also taking seeds and fruits of plants such as Acnistus, Rubus, Acalypha, Solanum, Morus, Heliotropium, Polygonum, grass, and also flower buds.

Breeding:
Pale-headed brush-finches breed in January-June. They form stable pairs that remain together all year. The nest is built by the female, consisting of an open cup made of grasses and bamboo, placed near the ground, occasionally up to 3 m above the ground, in a scrub, small tree or bamboo thicket. The female lays 1-3 eggs, which she incubates alone for 11-17 days. The chicks are fed by both parents and fledge 10-14 days after hatching, but continue to be fed for another 2 months and often remain with the parents for nearly a year.

Conservation:
IUCN status - EN (Endangered)
This species has an extremely small breeding range and the global population appears to number just 226 individuals. The pale-headed brush-finch was believed to be extinct since the 1960s, but was rediscovered in 1998. Since then the population seems to be increasing rapidly, from as little as 20 individuals to over 200, but it may reach carrying capacity soon. The main threats affecting this species are habitat loss and brood parasitism by shiny cowbirds Molothrus bonariensis. Conservation actions underway included the purchase and fencing of the few remaining patches of suitable habitat and cowbird control. A habitat management scheme was implemented in order to halt vegetation succession and create suitable habitat by selective thinning of dense thickets, which seems to have been quite successful.
