Variable Shrikethrush
Colluricincla fortis
A chunky bird with a thick bill. Quite plain: brownish on the back, grayish on the head, and paler below, with indistinct breast streaking. Color of the underparts varies geographically from dull rufous to whitish-buff. Found at low and middle elevations in humid forest, including secondary forest. Rich, melodious, variable song consists of several penetrating whistles, generally in an up-and-down pattern. Calls include “chek” notes. Somewhat similar to Rusty Pitohui, but smaller, with a dark rather than pale eye. Also similar to Gray Shrikethrush, but smaller, shorter-tailed, and browner, with a darker face. Could be confused with female Black Shrikethrush, but always smaller and paler.

South Island Wren
Xenicus gilviventris
A perky, upright wren restricted to alpine regions in the South Island of New Zealand. Has a very short tail and rounded wings, but distinctive long legs and toes. Male is a mossy green above and pale gray below, with noticeable yellow flanks and a creamy eyebrow. Female has duller plumage. Stance is often erect; constantly bobs up and down, flicking its wings, before hopping and running. Flies very short distances. Seen out in the open in rocky boulder fields, hence its common New Zealand name of “rock wren.” Gives a high-pitched three-note call which travels well in the open alpine terrain. Pairs will sometimes duet.
Gorgeted Wood-Quail
Odontophorus strophium
Scarce quail restricted to cloud forest in the northern half of Colombia’s eastern Andes. Adult has distinctive black and white crescents on the throat, which may be reduced or lacking in young birds. Male has chestnut underparts and white spots on the breast; female has gray underparts. Shy and not often seen, but with luck it may be encountered in small groups that walk on the forest floor. Song is like that of other wood-quails, a long and rollicking series of whistles.
Diademed Sandpiper-Plover
Phegornis mitchellii
Unique little shorebird, found very locally in the high Andes on bogs, lakeshores, and gravel bars in rivers and streams. Usually in pairs or family groups; does not mix with other species. Runs and bobs with a nervous gait, and feeds by probing with its weevil-like bill. Flights usually short and low, rather bounding. Despite boldly patterned plumage, it can blend in well with stony substrates. Note black head with a white diadem, a rusty nape, and fine dark barring on underparts.
