Rufous-webbed Brilliant
Heliodoxa branickii
Large, green hummingbird of montane forest. Males have a small red throat patch; females are duller green with a white-speckled belly. Both sexes have reddish-brown coloration on the inner webbing of wing feathers, giving the wings a brownish appearance in flight. Locally distributed, and often quite rare; it seems to be most common on some outlying ridges on the eastern side of the Andes.
识别特征
The rufous-webbed brilliant is 11 to 11.5 cm (4.3 to 4.5 in) long. Males weigh about 5.8 g (0.20 oz) on average and females 5.4 g (0.19 oz). The species' English name comes from its cinnamon-rufous inner wing feathers; the rest of the wing is dusky. Both sexes have a black bill whose mandible base is paler. Males are mostly shining dark green. Their forehead is brighter glittering green and they have an iridescent rosy gorget. The undertail coverts are bright white. The central pair of tail feathers are green and the rest dark blue. Females also have shining dark green upperparts, flanks, and breast. They have a short white streak from the bill to below the eye. The throat and breast are white, with shining green tips to the feathers, and the belly is white to buffy. A gorget is often lacking, and when present is paler and yellower than the male's. The undertail coverts are bright white like the male's, but the blue outer tail feathers have white tips.
分类信息
The rufous-webbed brilliant was at one time treated as the sole member of genus Lampraster, which in the mid 20th century was merged into the present genus Heliodoxa. It is monotypic.

Fox Sparrow
Passerella iliaca
Large, dark sparrow with extensive geographic variation. Larger than Song Sparrow, and generally darker with thicker streaking. Four groups of subspecies: Red (only subspecies found in eastern U.S., but breeds to Alaska), Slate-colored (Rockies), Sooty (Pacific Northwest), Thick-billed (California). Habitat varies across range, but generally breeds in forests with thick understory, often with plenty of conifers. In winter, tends to occur in dense thickets. Forages mainly on the ground in search of seeds. Visits feeders.
