O Anisognathus igniventris (Anisognathus igniventris) é um pássaro comum e inconfundível. É maioritariamente preto, com um ventre vermelho vivo, uma mancha vermelha nas orelhas e uma garupa e ombro azuis. As aves jovens são cor de laranja em vez de vermelhas. Pares ou pequenos bandos forrageiam em todos os níveis da floresta montanhosa e bordas, muitas vezes com bandos de espécies mistas. Ocorre desde o extremo oeste da Venezuela até à Bolívia, entre os 2.600 e os 3.600 m. Ouça o seu estranho canto: uma mistura de guinchos e tilintares.
Habitats e distribuição
This vibrant bird primarily inhabits montane forests, preferring the subtropical and temperate zones ranging from 2,400 to 3,500 meters above sea level. It is typically found in dense, humid forests and forest edges, often in areas with rich undergrowth and a thick canopy that provide ample food sources and protection. The Scarlet-bellied Mountain Tanager is closely associated with Andean montane cloud forests, where it can thrive in the cool, moist conditions. Geographically, this species is distributed across the northern Andes, specifically in Colombia, Ecuador, Peru, and Venezuela. Its range is primarily within the Andean cordillera, where it can be found flitting through the foliage and occasionally venturing into secondary forests and garden areas. Despite the broad range, it is more commonly observed in localized regions where the specific habitat conditions match its ecological needs.
Comportamentos e reprodução
The Scarlet-bellied Mountain Tanager typically exhibits strong pair bonds during the breeding season, often engaging in coordinated displays and vocalizations to attract mates. These tanagers are generally monogamous, with both the male and female sharing responsibilities such as nest building, incubation of eggs, and feeding of the young. The nests are usually well-concealed among dense foliage or high-altitude shrubbery, ensuring protection from predators. Socially, they are often seen in small groups or pairs, and may join mixed-species flocks outside of the breeding season, which helps them forage more efficiently. Unique to their reproductive strategy, the species tends to nest in areas with abundant food resources, ensuring that the chicks have a higher survival rate. This strategic placement helps them raise their young with minimal competition for food from other bird species.

Estado de conservação e esforços
The Scarlet-bellied Mountain Tanager (Anisognathus igniventris) is currently classified as Least Concern by the IUCN, reflecting a relatively stable population trend. However, its habitat is under pressure from deforestation and human encroachment, which remain primary threats to its long-term survival. The bird inhabits montane forests in the Andes, regions that are increasingly impacted by agricultural expansion and logging activities. To address these challenges, conservation efforts have focused on habitat preservation and restoration. Protected areas within the Andean region serve as crucial refuges for the species, and there are ongoing initiatives to promote sustainable land-use practices among local communities. Environmental organizations and governments work together to monitor population trends and enforce regulations that mitigate habitat destruction. Awareness campaigns also aim to highlight the importance of conserving high-altitude ecosystems that support the Scarlet-bellied Mountain Tanager and other endemic species.
