American Goldfinch
Spinus tristis
The American goldfinch is a small finch, 11–14 cm (4.3–5.5 in) long, with a wingspan of 19–22 cm (7.5–8.7 in). It weighs between 11–20 g (0.39–0.71 oz). Among standard measurements, the wing chord is 6.5 to 7.8 cm (2.6 to 3.1 in), the tail is 4.2 to 5.1 cm (1.7 to 2.0 in), the culmen is 0.9 to 1.1 cm (0.35 to 0.43 in) and the tarsus is 1.2 to 1.4 cm (0.47 to 0.55 in). The beak is small, conical, and pink for most of the year, but turns bright orange with the spring molt in both sexes.

Pine Siskin
Spinus pinus
These birds are fairly small, being around the same size as the widespread American goldfinch. In both sexes, total length can range from 11–14 cm (4.3–5.5 in), with a wingspan of 18–22 cm (7.1–8.7 in) and a weight of 12–18 g (0.42–0.63 oz). Adults are brown on the upperparts and pale on the underparts, with heavy streaking throughout. They have short, forked tails. Their bills are conical like most finches but are more elongated and slender than those of other co-occurring finches.
