Oriental Reed Warbler

Acrocephalus orientalis

In breeding range, this large, long-billed songster of expansive reedbeds can often be seen perched on top of a stalk belting its heart out, but on wintering grounds, it is more likely to be detected by a harsh, grating rattling from deep within the vegetation. Unremarkably plumaged, brown above, paler below, with a weak white supercilium and a short bristly crest, occasionally raised. Compare with other large reed warblers, especially Clamorous Reed Warbler.

Makatea Fruit-Dove

Ptilinopus chalcurus

A relatively slender fruit-dove that appears mostly green with a greenish belly, a silver chest and head, a magenta forehead, and an orange bill. Similar to Atoll Fruit-Dove, but much more boldly colored, with dark instead of pink legs. The two species are unlikely to be found on the same islands. Call is usually a couple of longer “woo” notes followed by an accelerated “laughing.”

Indian Nuthatch

Sitta castanea

Only nuthatch in most of its range with gray upperparts and brick-red underparts. From crown to upper mantle, the gray is a lighter shade than the remainder of the upperparts. Strong dark eye-stripe starts from the bill, broadening toward the sides of the neck, contrasting with the white throat. Female is similar but has lighter chestnut underparts and dirty white on the throat. In a narrow zone where it overlaps with the very similar Chestnut-bellied Nuthatch, Indian differs in the contrastingly paler crown and nape, the smaller bill, and the lack of white scallops on the vent. Primarily seen in deciduous forests; occurs in pairs or family groups, sometimes along with Velvet-fronted Nuthatches, with which it broadly overlaps in range. Call is a loud, mellow, rapid trill of 7-8 notes: “pi-pi-pi-pi-pi-pi.”

Spotted Elachura

Elachura formosa

Tiny wrenlike skulker with a large-headed and short-tailed profile. Brown overall with galaxy-like white spotting across the body and thick brick-red barring on the wings and tail. Difficult to see; almost always detected by its song, a drawn-out series of high chinking notes; responsive to whistled imitations, but very shy regardless and only infrequently breaks cover. Typically found in hilly forests, particularly next to well-shaded small streams and other damp areas.

Black-tailed Trainbearer

Lesbia victoriae

Small hummingbird with an exceptionally long tail. Green overall with a fairly short, slightly decurved bill. The male’s long tail is striking. Sexes similar but females are more spotted below and have a shorter tail. Could be confused with Long-tailed Sylph, but the trainbearer occurs in dry, scrubby, open habitats, not in forests. Compare with very similar Green-tailed Trainbearer; Black-tailed has a longer, more decurved bill, a longer tail that usually looks slightly curved, and is somewhat duller green. Occurs from Colombia to Peru, from around 2,500 to 3,800 m. Occasionally visits feeders, but more often seen feeding at flowering shrubs.

Spotted Crocias

Laniellus albonotatus

Long-tailed and thick-billed relative of the laughingthrushes, found only in foothill and lower montane forests on Java. Hops about in the upper levels of the forest, often in small single-species groups, as well as mixed flocks. When seen from below, note the bright white throat, black face, pale yellowish belly, and dark undertail with white-tipped feathers. If seen at a level angle, note rust-and-white striped back and sides. Fast, repetitive, up-and-down song is often given by multiple birds at once.

Buff-breasted Tody-Tyrant

Hemitriccus mirandae

Unobtrusive, drab little brownish flycatcher. Olive-backed, pale below, with the head looking disproportionately large compared to the rest of the body. Note the buff lores and eye-ring. Inhabits remnant humid forest patches at higher elevations. Sings a sharp series of “kit-kit-kit-kiit-kiit-kiiit-kit” notes.

White-chested Emerald

Chrysuronia brevirostris

Small hummingbird with short, black bill and completely white underparts; found in savannas, dry forests, and disturbed habitats. Hovers at flowers like other hummingbirds. Males sing a hard, rattling trill from exposed perches beneath forest canopy. Most similar to Plain-bellied and Versicolored Emeralds, but has shorter, entirely black bill; where these species occur together, White-chested may not be safely separable from them if not seen well.

River Lapwing

Vanellus duvaucelii

The black, gray, and brown coloration of this medium-sized shorebird makes it unmistakable. Raises black crest when displaying. As the name suggests, this species is primarily tied to rivers, where it is often seen foraging in pairs on riverbanks or exposed islands. Calls shrilly and loudly, both during display and when alarmed.

Aceh Bulbul

Pycnonotus snouckaerti

Rare and declining endemic of Sumatra’s northwestern mountains. Large grayish-brown bulbul with a bright orange forehead patch, dark olive wings, and a weak crest that gives it a pointy-headed profile. Once regarded as a subspecies of the very similar Orange-spotted Bulbul, but note present species’ distribution and dark (not white) belly. Inhabits foothill and lower montane forests, where localized and largely restricted to clearings with a substantial understory. Calls are generally similar to those of Orange-spotted Bulbul, and include a bubbly chatter.

Tuamotu Sandpiper

Prosobonia parvirostris

A small, very dark brown shorebird with a very short thin bill and a distinct white eyebrow. Upperparts spotted with buff, underside spotted or barred with brown. Legs yellow or grayish. In flight, looks very dark with very rounded wings. Prefers coastal shoreline and bare gravel of tiny atolls. Combination of odd proportions, very short thin bill, and white eyebrow should make this species unmistakable. Most common call is a nasal “kek,” but when excited gives a loud piping whistle and a series of rising and falling trills.

White-bellied Seedsnipe

Attagis malouinus

Chunky, generally scarce, rather grouselike bird of bleak moorland, bogs, and rocky slopes above timberline; in winter, sometimes descends to lowland Patagonian steppe, when it can be seen along roadsides. Found in pairs or small groups. Lacey “chainmail” pattern to upperparts is beautifully cryptic, and birds sometimes freeze when alarmed making them more difficult to see. No similar species in range; note the short stout bill and contrasting snowy-white belly. Flight strong and fast; flushes with loud shrieking choruses.

Smooth-billed Ani

Crotophaga ani

Anis are bizarre, coal-black cuckoos with long floppy tails and unique, curiously tall, flattened bills. Smooth-billed occurs in a variety of open and semi-open habitats in tropical lowlands and foothills, typically staying low in shrubs and grasses. Gregarious and not particularly graceful; usually seen crashing around awkwardly in small groups. Flies with choppy wingbeats and long glides. Widespread and common throughout much of South America and the Caribbean, extending as far west as the Pacific slope of Costa Rica and north to Florida. Compare with the very similar Groove-billed Ani, which overlaps in some areas of Central and South America. Note especially the bill shape: Smooth-billed often (but not always) has a taller ridge on the top of the bill, and a sharper angle on the lower edge of the bill. The sides are typically smooth, rarely with weak grooves. Voice is also important: listen for a rising, hawklike whistle with an inflection at the end. Dark eye, size, and habitat help separate from Greater Ani in South America and Panama.

Osprey

Pandion haliaetus

Large, mostly white raptor that cruises over lakes, rivers, and coastal waterways in search of fish. Impressively widespread: found on every continent except Antarctica. Mostly white head and underparts; dark brown back. In flight, holds wings with a kink in the wrist (shaped like an "M"). Stick nests are conspicuous on top of channel markers, utility poles and high platforms near water. Often seen plunging feet-first into water from high in the air to grab fish.

White-breasted Nuthatch

Sitta carolinensis

The largest nuthatch in North America, with distinctive white face, black cap, and blue-gray upperparts. Also note rusty lower belly and undertail coverts. Females have a slightly paler crown than males. Fairly common and widespread, usually in mature woodlands with large trees. Creeps along tree trunks and branches, often upside-down. Sometimes joins mixed flocks with other songbirds. Visits feeders. Listen for insistent yammering calls. Some subtle variation across range, mainly in the darkness of the sides and back, width of the black crown, and vocalizations.

Spotted Bowerbird

Chlamydera maculata

A brownish, mottled, strongly marked bowerbird with warm brown tones overall and a small pink crest on the nape. Loud rasping calls include hisses and squawks. Occurs in open woodlands, as well as in gardens and town parks within its range. Males decorate their avenue bowers with pale objects such as small bones and shells. Western Bowerbird is paler, and its range is further west. Spotted Bowerbird lives in inland portions of Queensland and New South Wales.

Eastern Wood-Pewee

Contopus virens

Drab grayish-brown flycatcher found in forested areas and edges. Nondescript overall with two pale wingbars; bill usually shows extensive orange on lower mandible. Note very long wings and larger size than Empidonax flycatchers. Typically seen on a high perch, occasionally sallying out to snatch an insect. Essentially identical to Western Wood-Pewee; averages paler overall with stronger upper wingbar, but reliably distinguished only by voice. Listen for clear whistled tones, especially the distinctive “PEE-a-weeEEE!” song.

White-headed Vanga

Artamella viridis

Mid-sized black-backed vanga with a typical bill. Males are pure white on the head and underparts, while females are pale gray. Madagascar endemic that is found at low and middle elevations in all forest types, and sometimes in adjacent plantations and scrub. Vocalizations include harsh scolds and penetrating hollow whistles. Larger than Chabert Vanga, with a completely pale head. Smaller than Sickle-billed Vanga, with a much shorter bill. 

Predicted Antwren

Herpsilochmus praedictus

Recently described Amazonian antwren. Males are gray with a bold white eyebrow and a black crown, wings, and tail. Females have white spots on a black crown and a rusty forehead. Found in humid forest, including seasonally flooded forest along big rivers and white sand forest, foraging from the middle levels to the canopy. Usually accompanies mixed-species flocks in the canopy. The song is a soft rolling trill. The rather similar male of the Aripuana Antwren has less black on the upperparts, and females have a paler forehead; Aripuana’s song is similar, but with fewer notes.

Purple-bearded Bee-eater

Meropogon forsteni

An unmistakable large bee-eater with elongated central tail feathers, a green back and uppertail, and a diagnostic deep purple face and throat. Purple throat is more extensive in males. Juveniles are greener below, less purple, and lack long central tail feathers. Typically found singly or in pairs in the understory and canopy of forests and forest clearings within the foothills and mountains of Sulawesi. Call is a distinctive, high-pitched “tsiyup,” slurred upward.
