Green-headed Tanager

Is a strikingly vibrant, medium-sized passerine bird characterized by its brilliant multicolored plumage, which makes it an ecological jewel of South American forests and a prime target for birdwatching and ornithological studies.

Is a strikingly vibrant, medium-sized passerine bird characterized by its brilliant multicolored plumage, measuring approximately 13.5 centimeters in length and weighing between 18 and 25 grams. The species exhibits a stunning array of colors: the head and sides of the neck are bathed in a brilliant turquoise blue, which contrasts sharply with a bright yellow-green crown. A distinct golden-yellow band wraps around the nape of the neck, while the throat and upper chest are marked by a deep black bib. The upper back is black, transitioning into a highly conspicuous orange-red lower back and rump. The breast and belly display a combination of greenish-blue and light green hues. Sexual dimorphism is minimal; females are slightly duller in color, showing a more greenish tone overall. Juveniles are mostly dull green and gray, lacking the intense multi-hued contrast of mature adults.

Geographical distribution: Occurs endemically in the eastern regions of South America. Its primary range is concentrated within the Atlantic Forest biome of southeastern and southern Brazil, spanning from the state of Bahia south to Rio Grande do Sul. It is also distributed in the northeastern corner of Argentina, specifically in the province of Misiones, as well as in the eastern forested regions of Paraguay.

Habitat: Inhabits the canopy and edges of humid tropical and subtropical forests, as well as mature secondary forests. This adaptable species can also be found in shaded agricultural landscapes like cacao plantations, fruit orchards, and urban parks near forested areas. Its elevational range extends from sea level up to 1,100 meters above sea level.

Feeding: Feeds primarily on a frugivorous diet, supplemented by small invertebrates. It actively searches for ripe fruits in the forest canopy, showing a strong preference for berries from the families Melastomataceae and Moraceae, especially the fruit of Cecropia trees. It also consumes nectar from flowers and captures small insects, spiders, and caterpillars by scanning the undersides of leaves. It is a common visitor to artificial feeding stations stocked with bananas and other fresh fruits.

Behavior: Is a highly social and active bird, usually observed in pairs or small family groups of 3 to 10 individuals. These groups frequently join larger mixed-species feeding flocks alongside other tanagers and forest passerines. It is an agile and restless forager, often hanging upside down from thin twigs to reach hanging fruit or probing bromeliad leaves. Its vocalization consists of sharp, metallic, high-pitched chirps used to maintain communication within the dense foliage.

Nesting: Occurs mainly during the spring and summer months of the Southern Hemisphere. The nest is a neat, open-cup structure constructed from dry leaves, plant fibers, moss, and bound together with spider silk. It is typically hidden in dense foliage, epiphytic bromeliads, or tangled vines, situated between 2 and 9 meters above the ground. The female lays a clutch of 2 to 4 pinkish-white eggs speckled with reddish-brown spots. The female incubates the eggs for about 12 to 14 days, during which the male helps defend the territory and occasionally brings food. Both parents actively feed the chicks a nutrient-rich insect diet until they fledge after approximately two weeks.

Conservation status: Is currently evaluated as Least Concern (LC) on the IUCN Red List of Threatened Species. Although its population is considered stable and it remains common within protected reserves, the severe fragmentation of the Atlantic Forest due to urban sprawl and agricultural expansion poses a persistent threat to its habitat connectivity.
