Great-billed hermit

Phaetornis malaris

Common name:
great-billed hermit (en); besourão-de-bico-grande (pt); ermite à long bec (fr); ermitaño piquigrande (es); langschnabeleremit (de)

Taxonomy:
Order Apodiformes
Family Trochilidae

Range:
This species occurs in three disjunct populations. One is found in Suriname, French Guyana and marginally into Amapá in northern Brazil. A second one is found from from southern Colombia and Venezuela down to central Bolivia and north-western Brazil. The third population is found along the coast of south-eastern Brazil, from Bahia to Espírito Santo.

Size:
These birds are 13-17 cm long and weigh around 6 g.

Habitat:
The great-billed hermit is mostly found in tropical rainforests, but also use swamp forests, moist scrublands and high-altitude scrublands. they are present from sea level up to an altitude of 2.400 m.

Diet:
They feed mainly on the nectar of various small, brightly coloured and scented flowers, but also take small insects and spiders.

Breeding:
Great-billed hermits are polygynous, with the males forming a lek where they display to attract females, having no futher part in the breeding process after mating. The female builds the nest alone, a cone woven from plant fibres with moss for camouflage. Spider webs are used to suspend it from a branch or the underside of a broad leaf, or less frequently under a bridge or from the rood of a building. The female lays 1-3 white eggs, which she incubates alone for 14-16 days. The chicks are raised by the mother and fledge 21-24 days after hatching. Each female raises a singe brood per season.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and is described as fairly common. It is suspected to lose 7,5-8% of suitable habitat within its distribution over the next decade based on a model of Amazonian deforestation, therefore being suspected to suffer a small decline in the near future.

Common name:
ruddy-tailed flycatcher (en); papa-moscas-uirapuru (pt); moucherolle rougequeue (fr); mosquerito colirrufo (es); rotschwanztyrann (de)

Taxonomy:
Order Passeriformes
Family Tyrannidae

Range:
This species is found from southernmost Mexico, Guatemala and Belize south to central Bolivia and brazil down to Mato Grosso, Tocantins and Maranhão.

Size:
These tiny flycatchers are 9-10 cm long and weigh 7 g.

Habitat:
The ruddy-tailed flycatcher is mostly found in moist tropical forests and swamp forests, often favouring forest clearings. They also use dry tropical forests and tall second growths. They are present from sea level up to an altitude of 1.200 m.

Diet:
They eat insects, particularly leafhoppers, either picking them from the foliage or hunting on the wing.

Breeding:
Ruddy-tailed flycatchers nests on a pear-shaped pouch of plant fibres and leaves with a side entrance, built by the female 2–6 m above the ground in the undergrowth of the forest and suspended from a twig or vine. The female lays 2 white eggs with chocolate-brown blotches, which she incubates alone for 15-22 days. The chicks are raised by the female alone and fledge about 19 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population estimated at 500.000-5.000.000 indivduals. The ruddy-tailed flycatcher is suspected to lose 15-17% of suitable habitat within its distribution over the next decade based on a model of Amazonian deforestation. It is therefore suspected to suffer a small decline in the near future.

Southern emuwren

Stipiturus malachurus

Common name:
southern emuwren (en);  carriça-australiana-meridional (pt); queue-de-gaze du sud (fr); maluro meridional (es); rotstirn-borstenschwanz (de)

Taxonomy:
Order Passeriformes
Family Maluridae

Range:
This species is endemic to Australia, being found along the southern coasts of the country from southern Queensland to south-eastern South Australia and in south-western Western Australia. It is also present in Tasmania.

Size:
These birds are 16-20 cm long, including the 10-11 cm long tail. They weigh 7-8 g.

Habitat:
The southern emuwren is mostly found in freshwater swamps with heaths, reeds and sedges, and in dry scrublands such as coastal heathland, but they also use deserts and rocky areas.

Diet:
They glean insects and spiders from the foliage, namely bugs, katydids, beetles, wasps, flies, ants, mantids and caterpillars. They are also known to take some vegetable matter including seeds


Breeding:
Southern emuwrens are socially monogamous and breed in August-March. The female builds the nest alone, consisting of an oval-shaped dome made of grasses and spider webs and lined with feathers. It is placed near the ground in a grass tussock or among dense scrubs. The female lays 2-4 eggs which she mainly incubates alone for about 12 days. The chicks are fed by both parents and fledge 8-11 days after hatching, but continue to rely on the parents for food for another 2-5 months. Each pair raises 1-2 broods per season and the young reach sexual maturity within their first year.

Conservation:
IUCN status - LC (Least Concern)
This species has a large breeding range and is reported to be uncommon. The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation, mainly through clearance for agriculture and construction of dams for water storage. Wildfires and the introduction of exotic predator and parasites may pose further threats to this species.

Common name:
square-tailed kite (en); milhafre-de-rabo-quadrado (pt); milan à queue carrée (fr); milano colicuadrado (es); schopfmilan (de)

Taxonomy:
Order Falconiformes
Family Accipitridae

Range:
This species is endemic to Australia, breeding from northern Queensland south to Victoria but being found throughout most of the country outside the breeding season, with the exceptions of northern South Australia and eastern Western Australia.

Size:
These birds are 50-55 cm long and have a wingspan of 130-145 cm. They weigh 450-650 g.

Habitat:The square-tailed kite is mostly found in coastal and sub-coastal, Eucalyptus dominated open forests and woodlands, and inland riparian woodlands. they also use coastal heathland, forest edges and wooded suburban areas. They are present from sea level up to an altitude of 1.000 m.

Diet:
They mostly hunt small birds, particularly honeyeaters, including their eggs and nestling, but also large insects, reptiles, frogs and small mammals.


Breeding:
Square-tailed kites are monogamous and mate for life. They breed in July-December and the nest is a large platform made of sticks and lined with green Eucalyptus leaves. It is placed in a fork in a tall tree, 8-34 m above the ground. The female lays 2-3 eggs, which are incubated by both sexes for 37-42 days. The chicks are fed by both parents and fledge 8-9 weeks after hatching, but only become fully independent 1-2 months later. Each pair raises a single clutch per year.


Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and the global population is estimated at 1.000-10.000 individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats. However, it may be vulnerable to certain activities which include habitat loss by logging, clearing and burning for cultivation and grazing, as well as illegal egg collection or hunting, nest disturbance and unsuitable fire regime management.
