Western Tanager
American Goldfinch
Western Tanager
Piranga ludoviciana
General appearance
The Western Tanager is a medium-sized bird, roughly the size of a Robin or Sparrow, measuring 6-7.5 inches (15-19 cm). Typically, the bird features a notched, rounded, or square-tipped tail. Its wings are pointed in shape and its bill is thicker than that of female orioles, making it strong and distinctive.
Male vs female
There exists a noticeable difference in physical traits between males and females. Male Western Tanagers boast brilliant colors, with a primarily yellow body, a black back and wings, and a unique red face. On the other hand, females are less vibrant. They display a duller yellow body with a grayish tone on their back and wings, but they do show two wing bars just like the males.
Juvenile
Juvenile Western Tanagers, similar to adult females, sport a dull yellow color. Their wings and back take on a gray shade, giving them a more subdued appearance than the brightly colored adult males. As they mature, their colors adjust to match their respective gender distinctions.

Spinus tristis
Also known as: Eastern Goldfinch, Wild Canary
General appearance
The American Goldfinch is roughly the size of a Sparrow, approximately 4.5-5 inches or 11-13 cm in length. It has a rounded wing shape and a notched tail. The bird's standout colorations are black, brown, gray, white, and particularly, yellow.
Male vs female
In summer, the male American Goldfinch is a vibrant yellow with black wings, tail, and forehead. This bold coloration makes it easy to spot. Conversely, summer female birds are a more subdued yellow-green. In winter, the colors of both males and females may vary from yellowish brown to gray, with notable, bold wing-bars of white or buff on black wings, and white tail spots.
Juvenile
The juveniles don't have the distinguishing yellow coloring of the adults. Their plumage tends to range from a dull brown to a gray color, making them trickier to identify. This less distinct appearance serves as a form of camouflage against potential predators.

Visual differences
The Western Tanager, measuring 6-7.5 inches, is larger than the 4.5-5 inch American Goldfinch. Male Western Tanagers have a striking red face with a yellow body and black wings, while male American Goldfinches are bright yellow with black wings and a forehead. The tanager has a thicker bill compared to the goldfinch's slender conical bill. The female tanager displays a dull yellow hue, whereas the female goldfinch exhibits a subdued yellow-green. Both species feature wing bars, but the tanager's overall coloration is more vivid and distinct.
Key differences and behavior
Western Tanagers and American Goldfinches exhibit distinct behavioral differences. Western Tanagers typically inhabit conifer or mixed forests, adapting to different environments during migration, including deserts. In contrast, American Goldfinches favor semi-open areas, adapting to orchards and suburban zones and extending to open fields in winter. Tanagers have an insect-rich diet, whereas Goldfinches are seed-eaters, with a preference for seeds from the daisy family. During breeding, Western Tanagers sing and chase their mates, nesting high in conifers, while American Goldfinches engage in fluttering flights and sing, nesting later in the season in shrubs or trees. Western Tanagers build strong, twig-based nests, whereas Goldfinches use plant fibers and spider webs. Tanagers may visit fruit-based feeders, whereas Goldfinches frequent feeders with small seeds like sunflower and nyjer. These behavioral distinctions help birders identify them beyond their visual traits.
