Mongolian Gull
Larus mongolicus
A large gull that breeds mainly inland, and migrates to the coast for the winter. Adults have a fairly pale gray back, pale eye, and dull yellow legs that can have a hint of pink coloration. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Variable plumage can make identification tricky. Occurs inland and along the coast, frequenting river mouths, harbors, beaches, lakes, and ponds. Often forms flocks with other gulls. Very similar to Vega Gull, and separation often difficult, but has a smaller head and bill; adults also generally have yellower legs.

Buru Cuckooshrike
Coracina fortis
A relatively large gray songbird with a notably heavy bill, a prominent black mark between the bill and the eye, and a paler belly. Singles and pairs frequent the canopy of forest within lowlands and mountains, including degraded forest. Confined to Buru. Differs from Pale Cicadabird in its larger size and extensive black area between bill and the eye. Differs from Common Cicadabird in its pale belly, larger size, and heavier bill. Call is a short, sharp, slightly burry “skeet.”
Scarlet-rumped Tanager
Ramphocelus passerinii
Fairly common in humid tropical lowlands. Favors evergreen forest edges, plantations, and verdant second growth, such as areas along roadsides. Forages mainly at low to middle levels often in fairly noisy small groups. Male is unmistakable if seen clearly: velvety black with a blinding scarlet rump. Female is very different: note distinctive bluish-white bill, tawny rump, and grayish head. Formerly known as Cherrie's Tanager and Passerini's Tanager.
Marble-faced Bristle-Tyrant
Pogonotriccus ophthalmicus
Small flycatcher found in foothill and subtropical forest from around 800-2200m. Grizzled face pattern with bold black and white crescent on cheek like some other bristle-tyrants and tyrannulets. Look for all dark bill and yellow wingbars to identify Marble-faced. Sexes alike. Found singly or in pairs, usually in lower to middle levels of forest, often following a mixed speices flock. Voice is also important: a descending sputter followed by a few rising “tseep!” notes.
