Tanager or Blue-and-Yellow Tanager?
Here's how to tell the difference
Tanager
Blue-and-Yellow Tanager
Tanager
Tangara, Stilpnia, Thraupis
General appearance
Tanager is a bird distinguished for its vibrant coloration, inclusive of shades such as red, orange, yellow, green, blue, and black. Their size ranges between 11cm to 20cm. The build is often compact, with stout bills and short wings. The Tanagers can be identified in wild by their striking colors and diverse vocalizations.
Male vs female
Males generally exhibit more striking and brighter colors than female tanagers. They often have deep red, blue, or yellow hues, whereas females lean more towards green or yellow-green and might sometimes appear more subdued. Further, some species show little to no difference in coloration between genders. Seasonal variations also exist, where the male's vibrant colors fade after the breeding period.
Juvenile
Juvenile tanagers typically wear modest plumage compared to adults. They usually share similarity with adult females in coloration, yet vary across species. In some species, juvenile males develop adult male coloration in gradual stages during months or years.

Rauenia bonariensis
General appearance
The blue-and-yellow tanager is a small, vibrant bird with striking coloration. It features a cobalt blue head and back, contrasted by a bright yellow belly and chest. The wings have a mix of dark blue and green, and its tail is predominantly blue. The bird's eyes are dark, and its beak is short and conical.
Male vs female
Males generally have a more vivid coloration compared to females. While both sexes share the blue and yellow pattern, the females tend to have duller shades and may appear slightly greener. This sexual dimorphism is subtle, often requiring close observation in natural light to distinguish.
Juvenile
Juvenile blue-and-yellow tanagers resemble adult females but are even less vibrant. The young birds are often more greenish-blue on the head and back, with a paler yellow belly. As they mature, the coloration intensifies. In the wild, juveniles can be seen following adults, gradually adopting the adult plumage without significant seasonal variation.

Visual differences
Tanagers (Tangara, Stilpnia, Thraupis) are 4.3-7.9 inches long, varying in vibrant colors like red, orange, green, and blue, while Blue-and-Yellow Tanagers are 6.1-7.5 inches with a distinct cobalt blue head, back, and yellow chest. Tanagers have stout bills; Blue-and-Yellow Tanagers possess a conical beak. Both display sexual dimorphism, but it's subtle in the latter. Juveniles of both species are duller, often greenish. Tanagers exhibit broader color diversity compared to the more uniform blue-and-yellow pattern of Blue-and-Yellow Tanagers.
Key differences and behavior
Tanagers (Tangara, Stilpnia, Thraupis) and Blue-and-Yellow Tanagers (Rauenia bonariensis) exhibit distinct behaviors despite both inhabiting tropical environments. While both engage in vibrant courtship displays, Tanagers are diverse, inhabiting neotropical regions, including temperate and alpine zones, while Blue-and-Yellow Tanagers typically prefer humid forest edges and are more adaptable to urban areas. Tanagers often nest in concealed areas and are generally more comfortable venturing into towns, whereas Blue-and-Yellow Tanagers, found in pairs or small groups, prefer more open woodland settings. Diet-wise, both consume fruits and insects, but Tanagers are also known for their affinity to nectar, foraging in trees, and being more frequent at bird feeders with fruity offerings. Tanagers exhibit a broader size range (4.3-7 inches), compared to Blue-and-Yellow Tanagers (6.1-7.5 inches). Though both display sexual dimorphism, juvenile Tanagers go through a prolonged coloration transition, whereas Blue-and-Yellow juveniles swiftly gain mature plumage.
