Short-tailed Grasswren

A small, short-tailed warbler-like songbird that moves in small flocks through the canopy of trees in forest, forest edge, and towns. Tit-hylias are unique in their streaked front halves and unicolored back halves, with black-and-white streaked heads, faces, throats, and chests and bright lemon yellow bellies, vents, and rumps. Wings and back are olive-green, becoming paler and more streaked toward the head. Vocalizations include high-pitched sibilant trills and “tsi-tsi-tsi” calls.

Small brown bird with large distribution from Costa Rica to Argentina. Rufous-brown overall with whitish eyebrow and a white stripe on the side of the face. Extensive streaking on crown and underparts separates from Plain Xenops. Compare with Slender-billed Xenops, which occurs primarily in lowland Amazonian forests where Streaked does not and is not as boldly streaked. Usually found singly or in pairs following a mixed-species flock. Occurs in mature forests and edges, from the understory to the canopy, but most often at middle levels. Can be found from the lowlands up to around 2,500 m.

A relatively small, entirely dark petrel, appearing chocolate-brown or black, with a distinctive short-necked and cigar-shaped silhouette due to its tapering tail. Lacks the white underside of the otherwise similar Beck’s Petrel, and is significantly smaller than and lacks the white belly of Tahiti Petrel. Similar to Bulwer’s Petrel, but lacks the pale bars found in the upperwing of that species, appears shorter-necked, and does not hold its head high in flight. Overall flight style of Fiji Petrel is more acrobatic than that of Bulwer’s Petrel.
