Blue-Necked Tanager
Scrub Tanager
Blue-Necked Tanager
Stilpnia cyanicollis
General appearance
The blue-necked tanager is a medium-sized bird characterized by striking, vibrant colors. Its name derives from its royal blue throat and chest. The rest of the body is mainly turquoise and green with varying shades. Its beak is short and quite sharp.
Male vs female
In the case of the blue-necked tanager, both males and females share a similar appearance with no significant differences. Both sexes exhibit the same bright blue neck and chest, and multicolored body. There's little to no sexual dimorphism, making them difficult to differentiate in the wild.
Juvenile
Juvenile blue-necked tanagers have a duller coloration compared to adults, often appearing more green than blue. While they share the same basic color pattern, their feathers lack the vibrant shine and intense colors of the adults. As they mature, their plumage will gradually brighten to match that of the adult birds.

A grayish head and nape are characteristic, alongside a distinct, sharp bill suited for their dietary needs.

Key differences and behavior
The Blue-Necked Tanager and Scrub Tanager exhibit distinct behavioral differences. Blue-Necked Tanagers are cooperative in breeding, with parents and family members sharing feeding duties for chicks, while Scrub Tanagers primarily pair-bond and are less socially inclined. Blue-Necked Tanagers frequent tropical lowland forests at elevations up to 8,202 feet, often visiting gardens, whereas Scrub Tanagers prefer montane forests and shrublands between 3,937 and 9,843 feet. The Blue-Necked Tanager shows a preference for sweet fruits and insects and is commonly drawn to fruit feeders, contrasting with the Scrub Tanager's diverse diet of fruits, insects, and occasional seeds, preferring natural food sources. Blue-Necked Tanager males perform elaborate dances in courtship, whereas Scrub Tanagers engage in song and aerial displays. Despite overlapping habitats in regions like Colombia and Ecuador, these behavioral traits aid in distinguishing the two species in the field.
