Taxonomy:
Order Passeriformes
Family Fringillidae

Range:
This species is native of the north-eastern Atlantic archipelagos of Madeira, Azores and the Canary islands. It has also been introduced to Bermuda, Puerto Rico and the Hawaiian Islands, and the domestic form is a popular cage bird worldwide.

Size:
These birds are 12,5-13,5 cm long and have a wingspan of 23 cm. They weigh 15-25 g.

Habitat:
The island canary is found in a variety of habitats, including dry scrublands, laurel forests, pine forests, open woodlands, pastures, arable land, orchards and rural gardens. They are present from sea level up to an altitude of 1.700 m.

Diet:
They forage mainly on the ground, taking the seeds of various grasses and weeds, but also eat fig seeds and the buds of leaves and flowers. During the breeding season the diet may be complemented with insects.

Breeding:
Island canaries breed in January-June. The nest is built by the female while the male defends the territory. The nest is an open cup made of grasses, roots and moss and lined with hair and feathers. It is placed high up in a thick scrub or tree. The female lays 3-5 pale blue-green eggs with reddish-brown spots, which she incubates alone for 13-14 days. The chicks are fed by both parents and fledge 14-17 days after hatching, but only become fully independent some 3 weeks later. They become sexually mature at 3-4 months of age. Each pair raises 1-2 broods per year.

Conservation:
IUCN status - LC (Least Concern)
This species has a relatively large breeding range and the global population is estimated at 60.000-300.000 individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Taxonomy:
Order Passeriformes
Family Estrildidae

Range:
This species is found in East Africa, from southern Tanzania, through Malawi and into central Mozambique and marginally across the border into Zimbabwe.

Size:
These birds are 13-14 cm long and weigh 14 g.

Habitat:
The lesser seedcracker is found in wet tropical grasslands and scrublands, and along the edges of tropical forests, typically favouring areas along rivers and streams or surrounding wetlands. They are present at altitudes of 700-1.800 m.

Diet:
They feed mainly on grass seeds, also taking small arthropods such as aphids, termites and spiders.

Breeding:
Lesser seedcrackers breed in December-May. The nest is mainly built by the male, consisting of an untidy oval structure with a short entrance tunnel on one side, made of broad strips of grass, reeds and leaves. It is typically placed in a fork of a tree or scrub, 1,5-3 m above ground. There the female lays 3-5 eggs which are incubated by both parents for about 15 days. The chicks fledge 20-23 days after hatching.

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

Swynnerton's robin

Swynnertonia swynnertoni

Common name:
Swynnerton's robin (en); pisco-de-peitilho (pt); rougegorge de Swynnerton (fr); ruiseñor de Swynnerton (es); swynnertonrötel (de)

Taxonomy:
Order Passeriformes
Family Muscicapidae

Range:
This African species is is restricted to a few mountains in eastern Zimbabwe, Mozambique and Tanzania, namely at Chirinda and a few other tiny forest patches along the border between Zimbabwe and Mozambique, in Mount Gorongosa and Mount Mabu in northern Mozambique, and in the Udzungwa Mountains and the East Usambara Mountains in Tanzania.

Size:
These birds are 13-14 cm long and weigh 14-20 g.

Habitat:
The Swynnerton's robn is mostly found in the understorey of mountain rainforests, also using lowland rainforests in Tanzania. They prefer dense undergrowth with a high density of saplings, or rank growth near streams. This species is present at altitudes of 150-1.850 m.

Diet:
They feed mainly on beetles, namely Buprestidae, Carabidae, Curculionidae, Elateridae and Scarabidae, but also take flies, wasps, bees, ants, spiders, millipedes and small frogs. fruits are also taken sometimes. They often catch prey fleeing from swarms of African driver ants Anomma wilverthi.

Breeding:
These birds breed in October-December. The nest is an open cup made of dead leaves, tendrils, rootlets, moss and leaf midribs, lined with dark plant fibres, and typically placed at the base of a dragon-tree Dracaena leaf, in a hollow of a tree stump, a forked stem of a scrub or on a platform formed by interlaced liana stems, up to 2 m above the ground. There the female lays 2-3 blue-green eggs with brown spots and blotches, which she incubates alone for 14-16 days. The chicks are fed by both parents and fledge 14 days after hatching.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small and very patchy breeding range. The global population is estimated at 2.500-10.000 individuals and is suspected to be declining, owing primarily to habitat clearance, degradation and disturbance across its range. The main causes for habitat loss and degradations are pole-cutting, firewood-collection, cultivation, clearance for new settlements, illegal pit-saw logging, gold mining, spread of non-native plants and uncontrolled fires. Conservation actions include protection areas, forest restoration and creation of corridors to link existing forest patches.
