Fulvous-chinned Nunlet
Nonnula sclateri
Chocolate-brown nunlet of mature rainforest. Usually fairly rare within its range; seems to occur mostly in upland ‘terra firme’ rainforest, where it occurs singly or in pairs in the undergrowth. Even-brown plumage and dull-orange patch at base of bill distinguish it from Rufous-capped Nunlet, which has a bright red-orange crown and orange throat and breast. Its song is a slow series of rising whistled “weep” notes, given at a rate of about one note per second.
Identification
The fulvous-chinned nunlet is 14 to 15.5 cm (5.5 to 6.1 in) long. Two males weighed 15.4 and 17 g (0.54 and 0.60 oz) and two females 19 and 19.9 g (0.67 and 0.70 oz). Its upperparts, wings, and tail are dull brown. Its lores are reddish brown and the cheeks dark gray. The chin is pale rufous ("fulvous") that blends to reddish brown on the throat and breast. The center of the belly is whitish and the flanks dull fulvous. The eye is brown with a narrow coral red or reddish purple ring around it. The maxilla is black, the mandible dark gray to greenish gray, and the feet gray to olive gray.
Taxonomy
The fulvous-chinned nunlet is monotypic. Its relationship to others of its genus has not been detailed but it is believed to be most closely related to the rusty-breasted nunlet (N. rubecula) and brown nunlet (N. brunnea). It has sometimes been considered conspecific with the latter.

Range and habitat
The fulvous-chinned nunlet is found in southwestern Amazonia south of the Amazon River, from eastern Peru and northern Bolivia east in southwestern Brazil as far as the Madeira River. It is entirely a bird of humid lowland forest, seldom being found above 300 m (980 ft) of elevation. It primarily inhabits the understory of upland terra firme forest but has also been reported at the edges of seasonally flooded várzea forest.

Other Birds
Golden-capped Parakeet
Aratinga auricapillus
Medium-sized parakeet with a long graduated tail. Usually seen in noisy groups in light woodland, savanna, farmland, and even urban areas. The body is mostly green and contrasts with its black bill, yellow crown, red forehead, and reddish belly patch. It has blue flight feathers, but in flight note the prominent orange underwings.
California Condor
Gymnogyps californianus
This behemoth is unmistakable solely due to its massive size, much larger than any other raptor or vulture. Adults are black with a white stripe on the underwing and an orange head. Wingtips are splayed into conspicuous fingertips. Young birds are duller with a gray head and only slightly paler stripe on the underwing. Found in very small numbers in coastal hills and mountains of California and around the Grand Canyon. Usually seen soaring singly or in pairs. Critically endangered; only recently has this species started breeding successfully again in the wild.
Long-toed Stint
Calidris subminuta
Tiny and slender “peep” of inland and coastal wetlands, where it is often found in well-vegetated areas such as fields and flooded meadows. Unlike most other small sandpipers in the region, this species has a distinctly long-winged and slender-bodied appearance. Breeding adult and juvenile recall much larger Sharp-tailed Sandpiper in pattern and color; nonbreeding adult rather plain mousy brown above, pale below. Note that long toes project slightly beyond tail in flight, unlike other stints. Flight call a quiet “prrrrp” similar to Curlew Sandpiper.
