Common name:
yellow-billed stork (en); cegonha-de-bico-amarelo (pt); tantale ibis (fr); tántalo africano (es); nimmersatt (de)

Taxonomy:
Order Ciconiiformes
Family Ciconiidae

Range:
This species is found throughout sub-Saharan Africa, from southern Mauritania and Mali to Sudan and Ethiopia and south to Namibia, Botswana and eastern South Africa. It is also found in north-western Madagascar.

Size:
These birds are 90-105 cm long and have a wingspan of 150-165 cm. They weigh 1,9-2,3 g.

Habitat:
The yellow-billed stork is shallow wetlands with sandbanks or trees for roosting, including swamps, the margins or river, lakes and lagoons, marshes, flooded grasslands, alkaline lakes, reservoirs, rice fields, and occasionally in estuaries, mudflats and beaches.

Diet:
They hunt small aquatic animals, including fishes, frogs, aquatic insects, worms, crustaceans and more rarely small mammals and birds.

Breeding:
Yellow-billed storks are monogamous and nest in colonies of 10-50 pairs, often alongside ibises, herons, spoonbills, other storks and cormorants. The nest is built by both sexes and consists of a large platform made of sticks and lined with fine leaves, grasses and reeds. It is placed on top of a tree, often an Acacia, water fig Ficus verruculosa or baobab Adansonia digitata, 3-7 m above the ground or water. The female lays 2-4 eggs which are incubated by both parents for about 30 days. The chicks are fed by both parents and fledge 55-60 days after hatching, becoming fully independent 1 month later.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range. Although there is no reliable information on population sizes and trends, overall the yellow-billed stork is believed to be declining due to wetland disturbance and destruction.

Common name:
grey-headed quail-dove (en); juriti-de-cabeça-cinzenta (pt); colombe de Gundlach (fr); camao (es); Gundlachtaube (de)

Taxonomy:
Order Columbiformes
Family Columbidae

Range:
This species is found in Cuba and the Dominican Republic. In Cuba it may still occur in patches throughout the country, but mainly on the Zapata Peninsula and Sierra del Rosario. In the Dominican Republic they occur on the Cordillera Central, Sierra de Baoruco and Sierra de Neiba. It possibly also occurred in Haiti until the early 20th century, but was extirpated by extensive habitat destruction.

Size:
These birds are 26-30 cm long and weigh 210 g.

Habitat:
The grey-headed quail-dove is mostly found in dry, limestone-based forests, but also uses rainforests, swamp forests and coffee plantations. They are present from sea level up to an altitude of 1.800 m.


Diet:
They forage on the ground, taking seeds and some small invertebrates.

Breeding:
These birds are monogamous and may pair for life. They breed in January-August, nesting in a loose bowl made of leaves, placed on the ground among the forest undergrowth. There the female lays 1-2 beige-coloured eggs which are incubated for about 13 days. The chicks fledge about 2 weeks after hatching.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively large but patchy breeding range. The global population is estimated at 1.500-7.000 individuals and is suspected to be declining rapidly, owing to habitat loss and hunting pressure. Habitat destruction as nearly wiped out this species on the Cordillera Central and Sierra de Neiba, mainly through the expansion of cacao, coffee and tobacco production. Further threats include dry-season burning, drainage, agricultural expansion and introduced predators, as well as heavy hunting in Cuba for human consumption. Conservation action include a hunting ban in the Dominican republic since the 1970s and a number of nature reserves in both Cuba and the Dominican Republic, although few are afforded strict protection.

It is placed in the horizontal surface of a dead or leafless branch. There the female lays 2-3 pale greenish-white eggs with black and grey blotches. The eggs are incubated by both sexes but there is no information on the length of the incubation and fledgling periods.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is described as locally common in the Indian subcontinent, common in Nepal, Bhutan and Sri Lanka; locally common in South-East Asia and common in China. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

This species is found in south-eastern Australia, in southern Queensland, New South Wales, Victoria and eastern South Australia.

Size:
These birds are 26-28 cm long and weigh 55-85 g.

Habitat:
The red-rumped parrot is mostly found in dry grasslands and open, sry savannas and forests, especially along rivers and streams, also using mangroves, dry scrublands, farmland and urban parks. They are present from sea level up to an altitude of 1.100 m.

Diet:
They forage mostly on the ground, usually in pairs or small flocks, taking seeds, grass leaves, shoots,fruits and flowers.

Breeding:
Red-rumped parrots breed in August-January. They are monogamous and mate for life. The nest is a hollow in an Eucalyptus tree, or sometimes on a fence post or nest box. The female lays 3-8 eggs, which she incubates alone for 19-21 days while being fed by the male. The chicks fledge 4-5 weeks after hatching, but continue to receive food from the parents for some time afterwards.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is reported to be common to abundant throughout this range. The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat. These birds are often hit by cars when feeding by roads, and hunted by domestic pets, especially cats.
