Typical Environment

Occurs from southern Peru through Bolivia to northern Chile and northwestern Argentina. It inhabits high-altitude shrubland, puna grassland, rocky slopes, and edges of Polylepis woodlands. Birds are often seen at weedy patches, bofedal margins, and open scrub near human settlements. Outside breeding, it may descend slightly to areas with abundant seed resources.

Useful to know

The black siskin is a high-Andean finch with striking sexual dimorphism: males are mostly jet black with vivid yellow in the wings and tail, while females are browner and more subdued. It frequents puna grasslands, Andean scrub, and Polylepis woodlands, often forming small flocks outside the breeding season. It can make altitudinal movements in response to weather and food availability.

Behaviour

Temperament

social and active

Flight Pattern

buoyant with short rapid wingbeats and undulating flight

Social Behavior

Often in pairs during the breeding season and in small flocks at other times, sometimes mixed with other finches. Likely monogamous, with cup nests placed in shrubs or low trees. The female primarily incubates while the male helps provide food.

Migratory Pattern

Partial migrant

Song Description

A lively, twittering series of trills and high-pitched notes. Flight calls are thin and tinkling, given in brief bursts as flocks move over open terrain.

Black skimmer

The black skimmer is a tern-like seabird, one of three similar bird species in the skimmer genus Rynchops in the gull family Laridae. It breeds in North and South America. Northern populations winter in the warmer waters of the Caribbean and the tropical and subtropical Pacific and Atlantic coasts, but South American populations make only shorter movements in response to annual floods which extend their feeding areas in the river shallows.

Black sparrowhawk

The black sparrowhawk, sometimes known as the black goshawk or great sparrowhawk, is a bird of prey belonging to the family Accipitridae. It was formerly placed in the genus Accipiter. It occurs mainly in forest and non-desert areas south of the Sahara, particularly where there are large trees suitable for nesting; favored habitat includes suburban and human-altered landscapes. It preys predominantly on birds of moderate size, such as pigeons and doves, in suburban areas.

Black stilt

The black stilt or kakī (Māori) is a wading bird found in New Zealand. It is one of the world's rarest birds, with 169 adults surviving in the wild as of May 2020. Adult kakī have distinctive black plumage, long pink legs, and a long thin black bill. Black stilts largely breed in the Mackenzie Basin in the South Island, and are threatened by introduced feral cats, ferrets, and hedgehogs as well as habitat degradation from hydroelectric dams, agriculture, and invasive weeds.

Black stork

The black stork is a large bird in the stork family Ciconiidae. It was first described by Carl Linnaeus in the 10th edition of his Systema Naturae. Measuring on average 95 to 100 cm from beak tip to end of tail with a 145-to-155 cm (57-to-61 in) wingspan, the adult black stork has mainly black plumage, with white underparts, long red legs and a long pointed red beak. A widespread but uncommon species, it breeds in scattered locations across Europe, and east across the Palearctic to the Pacific Ocean. It is a long-distance migrant, with European populations wintering in tropical Sub-Saharan Africa, and Asian populations in the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing broad expanses of the Mediterranean Sea and detours via the Levant in the east, the Strait of Sicily in the center, or the Strait of Gibraltar in the west. An isolated non-migratory population lives in Southern Africa.
