Common name:
orange-throated tanager (en); saíra-de-papo-laranja (pt); tangara à gorge orangée (fr); tangara golinaranja (es); veilchenschultertangare (de)

Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
This species is only found in a small area of northern Peru, in the eastern slopes and foothills of the Andes above the rivers Marañón and Cenepa, in the forests at the headwaters of the río Nieva, and marginallt into Ecuador on the western slopes above the río Nangaritza.

Size:
These birds are 17 cm long and weigh 43,5-56 g.

Habitat:
The orange-throated tanager is mostly found in mature, humid terra firme forests and foothill forests, also using disturbed forests. They are present at altitudes of 450-1.000 m.

Diet:
They feed on fruits, seeds and insects such as beetles.

Breeding:
Orange-throated tanagers breed in January-March. They are cooperative breeders, with helpers participating in nest defence and provisioning. The nest is an open cup made of twigs, dead plant material, moss and lichens, and is placed in the uppermost fronds of a palm tree, about 10 m above the ground. There is no information on clutch size, but the incubation period is believed to take 18-20 days. There is no available data regarding the fledging period.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small breeding range and the global population is estimated at just 6.000-15.000 individuals. The orange-throated tanager is suspected to lose 6% of suitable habitat within its distribution over the next decade, based on a model of Amazonian deforestation, being therefore suspected to suffer decline a small decline in the near future.

Common name:
Parodi's hemispingus (en); hemispingo-de-Parodi (pt); tangara de Parodi (fr); hemispingo de Parodi (es); gelbbrauenhemispingus (de)

Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
This species is endemic to Peru, only being in the eastern slopes of the Andes in the south central part of the country, from the Cordillera Vilcabamba south to the upper Urubamba valley.

Size:
These birds are 14-16 cm long and weigh about 20 g.

Habitat:
The Parodi's hemispingus is found in mountain rainforests, including elfin forests, and in patches of Chusquea bamboo at or near the treeline. They occur at altitudes of 2.600-3.500 m.

Diet:
They forage in small groups, often together with other insectivores, taking various arthropods.

Breeding:
These birds possibly breed from July onwards. Otherwise, there is no further information the regarding the reproduction of this species.

Conservation:
IUCN status - NT (Near-Threatened)
This species has a relatively large breeding range and is described as fairly common. However, it is suspected to lose 25% of suitable habitat within its distribution over the next decade based on a model of Amazonian deforestation, suggesting it will undergo a moderate decline in the near future. The main threat to the Parodi's hemispingus is the accelerating deforestation in the Amazon Basin as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network.

Tamarugo conebill

Conirostrum tamarugense

Photo by Gonzalo Gonzalez (Internet Bird Collection)

Common name:
tamarugo conebill (en); figuinha-do-tamarugo (pt); conirostre des tamarugos (fr); comesebo de los tamarugales (es); rotstirn-spitzschnabel (de)

Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
This species is only found breeding in a few locations within Pampa del Tamarugal, in northern Chile. They migrate north to winter other parts of northern Chile and in south-western Peru.

Size:
These birds are 12-13 cm long and weigh about 10 g.

Habitat:
The tamarugo conebill is mostly found breeding in mature tamarugo Prosopis tamarugo plantations, but can also use riverine scrublands, agricultural land and citrus groves. outside the breeding season, it occurs primarily in arid Gynoxys and Polylepis stands. They can be found from sea level up to an altitude of 4.100 m.

Diet:
They feed mainly on caterpillars, particularly those of Leptotes trigemmatus.

Breeding:
Tamarugo conebills breed in September-December, coinciding with the seasonal blooming of tamarugo flowers which provide food for the caterpillars the birds rely on. They nest in a deep, round cup made of small twigs, feathers, wool and the rachis of tamarugo leaves. The nest is placed in a descending or horizontal branch near the centre of a tamarugo tree, about 3-6 m above the ground. The female lays 3 pale grey eggs with brown spots. There is no available information regarding the incubation and fledgling periods.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small and fragmented breeding range. The global population has been estimated at 19.000-51.000 individuals, but this estimate may by outdated. The population is possibly increasing, owing to the expansion and regeneration of tamarugo forests. Tamarugo was almost extirpated by the time the Chilean government began a replantation programme in the 1930s. The tamarugo is managed mainly for the production of sheep forage and by the 1970s, 146 square quilometres had been reforested, and protected within the Pampa del Tamarugal National Reserve. Potential threats include ongoing attempts to control L. trigemmatus with chemicals or parasitoids, the risk of exhaustion of the aquifers used to water taramugo plantation due to their use to supply the city of Iquique, and the widespread cutting of Polylepis woodland in the wintering areas.

Common name:
black-and-white tanager (en); tiê-preto-e-branco (pt); tangara à miroir blanc (fr); tangara albinegra (es); spiegeltangare (de)

Taxonomy:
Order Passeriformes
Family Thraupidae

Range:
This species breeds in the western slope of the Andes in south-western Ecuador and north-western Peru. They migrate east to winter on the eastern slopes of the Andes in Peruvian Amazonia and marginally into Brazil and Bolivia.

Size:
These birds are 16 cm long and weigh 23-28 g.

Habitat:
The black-and-white tanager breeds in deciduous woodland, gallery forests and riparian thickets up to an altitude of 1.950 m. outside the breeding season they move to lower altitudes and use the edges of tropical rainforests, second growths and riparian habitats.

Diet:
They feed on insects and seeds.

Breeding:
These birds breed in February-May. The nest is an untidy, loosely woven cup made of sticks and leaf petioles, lined with dark fungal rhizomorphs. It is placed in a small tree or scrub, 0,5-2,5 m above the ground. There the female lays 3-4 whitish to pale bluish eggs with reddish-brown and black speckles and blotches. There is no information regarding the incubation and fledgling periods.

Conservation:
IUCN status - NT (Near-Threatened)
This species has a relatively large breeding range, but is described as uncommon and patchily distributed. The black-and-white tanager is suspected to lose 10% of suitable habitat within its distribution over the next decade, based on a model of Amazonian deforestation and is therefore expected to suffer a small decline in the near future. It is threatened by deforestation and understorey degradation, which may be further isolating populations within its already disjunct range.

Breeding:
Scarlet tanagers breed in May-August. They are monogamous and the female builds the nest, a flimsy cup woven with twigs, grasses, plant stalks, bark strips, rootlets, and pine needles. The nest is lined with grass, fine rootlets, fine plant fibres, vine tendrils, and pine needles, and it is placed in a fork in a tree, up to 15 m above the ground. She lays 3-5 greenish-blue or light blue eggs with chestnut, purplish red, and lilac speckles, which are incubated for 12-14 days. The chicks are fed by both parents and fledge 9-15 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population estimated at 2,2 million individuals. The scarlet tanager has had stable population trends over the last 4 decades.
