Brazilian Tanager

An exceptionally vibrant passerine bird belonging to the species-rich Thraupidae family, renowned for its dazzling plumage. This species displays a highly pronounced sexual dimorphism. Adult males exhibit an intense, glowing crimson-red plumage across their entire body, creating a striking contrast with their jet-black wings and tail feathers. A highly diagnostic anatomical feature of the male is the swollen base of the lower mandible, which presents a brilliant, reflective silvery-white patch that is easily visible even in low-light forest understories. Conversely, the adult females possess a much duller and cryptic coloration, featuring grayish-brown upperparts and a subdued, warm reddish-brown wash on the lower belly and rump, aiding in camouflage during parental duties. Juvenile individuals closely resemble adult females, only developing the stark adult male coloration after subsequent molts. On average, adult specimens reach a total body length of 19 centimeters and maintain a body weight ranging between 28 and 35 grams, boasting a robust, conical bill designed for an omnivorous diet.

Geographical distribution This species is endemic to the eastern coastal strip of South America. Its geographic range is restricted entirely to Brazil, stretching continuously from the northeastern states of Paraíba and Rio Grande do Norte southward through the coastal states of Bahia, Espírito Santo, Rio de Janeiro, São Paulo, and Paraná, reaching its southernmost limits in Santa Catarina and the northeastern fringes of Rio Grande do Sul.

Habitat: Primarily associated with the hyper-diverse and humid Atlantic Forest biome. It thrives in restingas (sandy coastal scrub vegetation), forest edges, secondary growth woodlands, shrubby clearings, and moist montane slopes. Furthermore, it exhibits a high tolerance for anthropogenically modified environments, frequently inhabiting suburban gardens, public parks, orchards, and abandoned agricultural lands where dense vegetation provides adequate shelter and nesting sites.

Feeding Highly omnivorous with a strong preference for frugivory. They consume various small fruits such as those from Cecropia trees, melastomes, and wild figs. They supplement their diet with animal protein, capturing spiders and small insects like caterpillars, grasshoppers, and beetles.

Behavior: Displaying a lively and restless temperament, these birds are typically observed in pairs or small family parties. They communicate via sharp, metallic calls and occasionally join mixed-species feeding flocks. Territoriality increases significantly during the breeding season.

Nesting The breeding season occurs during the southern spring and summer. The female constructs a cup-shaped nest woven from dry leaves, grass fibers, and rootlets, typically placed in low shrubs at heights of 1 to 2 meters off the ground. The female lays 2 to 3 greenish-blue eggs speckled with dark brown or black spots. Incubation lasts approximately 13 to 14 days and is performed solely by the female, although both parents actively feed the nestlings.

Conservation status Listed as Least Concern (LC) on the IUCN Red List. However, local populations face severe pressure due to deforestation and urbanization within its range.
