Ovenbird
Seiurus aurocapilla
Secretive warbler that lacks vibrant colors, but compensates with an enormous voice. Olive-brown above with black streaks on white breast and bold white eyering. Orange central crown stripe bordered by black on either side. Forages for insects by walking along branches and on the ground with exaggerated footsteps and bobbing gait. Breeds primarily in areas with extensive deciduous or mixed forest. Winters primarily in Middle America and the Caribbean, where it can be quiet and difficult to detect. On the breeding grounds, listen for its loud song that builds in volume: “tea-cher, TEA-cher, TEA-CHER!”; also gives a sharp, high-pitched, metallic chip year-round. Possible to confuse with thrushes, but smaller, and walks instead of hops.
Identification
Ovenbirds are large wood warblers and may sometimes be confused by the untrained for a thrush. Adults measure 11–16 cm (4.3–6.3 in) long and span 19–26 cm (7.5–10.2 in) across the wings. They weigh 19 g (0.67 oz) on average, with a range of 14–28.8 g (0.49–1.02 oz). Among standard measurements, the wing chord is 6.8 to 8.3 cm (2.7 to 3.3 in), the tail is 5 to 5.8 cm (2.0 to 2.3 in), the bill is 1.1 to 1.3 cm (0.43 to 0.51 in) and the tarsus is 2 to 2.3 cm (0.79 to 0.91 in). They tend to be heavier in winter and particularly at the start of their migration. They have olive-brown upperparts and white underparts heavily streaked with black; the flanks have an olive hue. A white ring surrounds the eyes, and a black stripe runs below the cheek. They have a line of orange feathers with olive-green tips running along the top of their head, bordered on each side with blackish-brown. The orange feathers can be erected to form a small crest. The eyes and the upper part of the thin pointed beak are dark, while the lower beak is horn-colored and the legs and feet are pinkish.<p>Males and females look alike. Immature birds have tawny fringes to the tertiary remiges and sometimes buff-tipped outer primary wing coverts. Most conspicuously, the olive-green tips of the crown feathers, which are hardly visible in adult birds, are far larger in extent in immatures and cover the orange crown-stripe almost or completely.<p>The main song of the ovenbird is a series of strident, relatively low-pitched, bisyallabic motives repeated without pause about eight times and increasing in volume. Usually, the second syllable in each motive is sharply accented: "chur-tee’ chur-tee’ chur-tee’ chur-tee’ chur-TEE chur-TEE chur-TEE!" Male ovenbirds utter a sweet chattering song in the air at twilight, after the manner of the skylark, incorporating portions of the main song into a jumble of sputtering notes and mimicry as they dive back to earth. The call is a variably pitched, sharp "chik!" Some variations recall the common call note of a downy woodpecker. If the bird is excited, it may repeat this call several times. The fight call is a high, rising siiii.
Taxonomy
The genus Seiurus is currently treated as monotypic, containing only the ovenbird; it is genetically distinct from all other species in the family Parulidae, probably the first genus to evolve separately from the rest of the family.<p>Before the recent genetic studies were carried out, the waterthrushes were also included in Seiurus; these are now treated separately in the genus Parkesia as they are not very closely related to the ovenbird.<p>The species name aurocapilla is a noun phrase, so the original spelling is retained, not changed according to the gender of the genus name; Linnaeus originally named it Motacilla aurocapilla, and the ending is not changed to -us as commonly cited in the past. Etymologically aurocapilla comes from Latin and means "golden haired" and Seiurus is from Ancient Greek seiō, "to shake", and oura, "tail".

Other Birds
Tawny-capped Euphonia
Euphonia anneae
Small finchlike bird, compact and short tailed. Generally yellow below and dark blue-black above with stout, short bill. To identify male euphonias, focus on crown and throat: on Tawny-capped, crown is entirely russet-orange and throat is dark. Female shows a more limited orangey forehead, which narrows down the options. Also note grayish (not olive or brown) belly. Often in pairs or small flocks with males, which makes identification easier. Frequents forested habitats and edges. Can form mixed feeding flocks with other species such as warblers and tanagers.
Sulawesi Pitta
Erythropitta celebensis
A round-bodied, short-tailed, long-legged terrestrial bird with a red belly. Broad, iridescent blue chest band is bordered with thick black lines. Reddish-brown crown shows an indistinct blue line. Also shows paler brown cheeks and green upperparts. Juvenile is brown with a pale bill base and gray eyes. Singles or pairs forage on forest floor in lowlands and foothills. Unmistakable in limited range on Sulawesi and adjacent islands. Song is a drawn-out, two-part whistle with a longer, trembling first note followed by a falling, mournful note: “waaaaaaaop-wooowow,” as is typical of the genus.
Amazilia Hummingbird
Amazilis amazilia
A green-and-chestnut hummingbird with plumage that varies throughout its range. All variants have a red bill with a black tip. In most of its range, it has a green throat, white breast, and chestnut belly and tail. In the southern part of its range, white breast is reduced or absent and throat is blue or blue-green. At its northern limit, tail is mostly green. In the Andes of southern Ecuador, underparts are mostly white with only a little chestnut. Common in dry forest and scrub, and less prevalent or absent in more humid areas.
