Golden-crowned Sparrow
Zonotrichia atricapilla
Measuring 15–18 cm (6–7 in) in length with a wingspan of 24.75 cm (9.74 in) and ranging from 19.0 to 35.4 g (0.67 to 1.25 oz) in mass, the adult golden-crowned sparrow is fairly large for an American sparrow. Like all Zonotrichia sparrows, it has a relatively long, square-tipped tail and a slightly peaked crown. Males and females are similarly plumaged, though males average slightly larger than females. Other than a plain gray nape, the adult's upperparts are grayish-brown, with broad brownish-black streaks on the back and scapulars, and an unstreaked rump. Voice: The song is a three-note whistle, descending in pitch. It is very distinctive, and often described as oh-dear-me. The call also sounds like the words I'm so weary, so Alaskan gold miners along the trails called this bird "Weary Willie". However, birds in the mountains of British Columbia have been reported to have a trill on the third note, rather than a clear whistle as in other populations.

White-throated Sparrow
Zonotrichia albicollis
The white-throated sparrow is a passerine bird of the New World sparrow family Passerellidae. It measures 15 to 19 cm (5.9 to 7.5 in) in length with a wingspan of 23 cm (9.1 in). Typical weight is 22 to 32 g (0.78 to 1.13 oz), with an average of 26 g (0.92 oz). Among standard measurements, the wing chord is 6.3 to 7.9 cm (2.5 to 3.1 in), the tail is 6.8 to 7.7 cm (2.7 to 3.0 in), the bill is 1 to 1.2 cm (0.39 to 0.47 in) and the tarsus is 2.2 to 2.4 cm (0.87 to 0.94 in). They are similar in appearance to the white-crowned sparrow, but with white throat markings and yellow lores. Voice: White-throated sparrows produce song laterally through the left side of their syrinx, and control of their syrinx involves both their central and peripheral nervous systems. After damage to motor control of the left side of the syrinx, individuals were still able to produce sound but their song pattern was distorted, indicating the left side chiefly controls their production of song.
