Common name:
white-bellied antpitta (en); tuvacuçu-de-barriga-branca (pt); grallaire à ventre blanc (fr); tororoí ventriblanco (es); blassbauch-ameisenpitta (de)

Taxonomy:
Order Passeriformes
Family Formicariidae

Range:
The white-bellied antpitta is found along the western slopes of the Andes, from northern Colombia to extreme northern Peru.

Size:
These birds are 16-18 cm long and weigh 62-69 g.

Habitat:
This species is mostly found on the floor and in the lower understorey of mountain rainforests, also using second growths to a lesser extent. they occur at altitudes of 1.400-2.300 m.

Diet:
They are known to eat insects, but there is little available information about their diet.

Breeding:
White-bellied antpittas breed in March-September and are presumed to be socially monogamous. The nest is a cup made of twigs and rootlets and placed in a fork in a tree about 1 m above the ground. The female lays 2 light greenish eggs with light brownish blotches. The eggs are incubated by both parents, but there is no information regarding the length of the incubation and fledging period.

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

Common name:
moustached antpitta (en); tuvacuçu-de-bigodes (pt); grallaire à moustaches (fr); tororoí bigotudo (es); grauscheitel-ameisenpitta (de)

Taxonomy:
Order Passeriformes
Family Formicariidae

Range:
This species is only found in the western slope of the Central Andes in Colombia, and both Andean slopes in northern Ecuador.

Size:
These birds are 16-17 cm long and weigh 60-80 g.

Habitat:
The moustached antpitta is found in dense understorey of moist, mossy cloud forests, particularly in ravines and steep slopes. They are present at altitudes of 1.800-2.500 m.

Diet:
They forage on the ground, taking earthworms and insects, namely katydids.

Breeding:
Moustached antpittas nest in a cup made of dead leaves, sticks and moss, placed on a small branch or trunk of a tree, about 1,5 m above the ground. The female lays 2 unmarked eggs. There is no available information about the incubation period, but the chicks fledge 15-17 days after hatching.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small and fragmented breeding range, and the global population is estimated at 1.500-7.000 individuals. The population is suspected to be declining a a slow rate due to habitat loss. Since the 17th century, most of the cloud forest in the central Andes of Colombia has been logged, settled and converted to agriculture, while the west Andean slopes in Ecuador have also been strongly altered and fragmented. The few remaining areas suffer from human encroachment and clearance for agriculture and opium production. In the east Andes some well protected forests remain with roughly 60% of the range of the moustached antpitta in that region being included in five protected areas.

Black-faced antthrush

Formicarius analis


Common name:
black-faced antthrush (en); tauoca (pt); tétéma coq-de-bois (fr); formicario enmascarado (es); graubrust-ameisendrossel (de)

Taxonomy:
Order Passeriformes
Family Formicariidae

Range:
This species is found in the neotropics from southern Mexico, through Central America to the northern regions of South America in Colombia, Venezuela, Trinidad and Brazil, and nearly in all of the Amazon Basin with the exception of the north-westernmost regions.

Size:
The black-faced antthrush is 17-19 cm long and weighs 59 g.

Habitat:
They are found in moist tropical and subtropical forests, at low and middle altitudes. More often in the forest interior than in the edges, always near the ground.

Diet:
The black-faced antthrush is mostly an insectivore, taking insects, spiders and other invertebrates from the foliage on the forest floor. They will often follow columns of army ants in order to take their prey and may occasionally capture small snakes, toads, and lizards.

Breeding:
These birds breed in February-May. They build a leaf-lined nest on a cavity in a hollow branch or stump. The nest is a mat of flowery material placed on a bottom of dead leaves with the entrance less than 4 m above the ground. The female lays 2 white eggs which are incubated by both parents for 19-20 days. The chicks fledge 18-19 days after hatching. Each pair may raise up to 3 broods in a season.

Conservation:
IUCN status - LC (Least concern)
The black-faced antthrush has a very large breeding range a global population estimated at 5-50 million individuals. This population is suspected to be stable in the absence of evidence for any declines or substantial threats, so the species is not threatened at present.
