Japanese Leaf Warbler
Phylloscopus xanthodryas
Small songbird, a member of the Arctic Warbler complex, this species looks essentially identical to Arctic Warbler and Kamchatka Leaf Warbler but is more evenly yellowish. Normally only distinguished in the field by breeding range and song: breeds in forests on all of the main Japanese islands except Hokkaido, where it is replaced in summer by Kamchatka Leaf Warbler. Favors foothill to montane areas with dense brushy understory; can be found in more open wooded habitats in migration and on wintering grounds. Song resembles that of Arctic in general pitch and register but is less uniform, like a more rising and falling version of Arctic’s song. Call also similar but averages lower in pitch.

Sapphire-bellied Hummingbird
Chrysuronia lilliae
Rare, endangered, and poorly known hummingbird restricted to mangroves and adjacent scrubby areas along the Colombian coast. Male has sapphire underparts extending from throat all the way to belly, and lacks the distinct hood typical of the more common Sapphire-throated Hummingbird. Female’s plumage is not known with certainty, but likely resembles female Sapphire-throated Hummingbird, which has white central underparts bordered by green flanks, and white tail tips.
Ouvea Parakeet
Eunymphicus uvaeensis
Spectacular, relatively large mostly green parakeet with a black face, slight bit of red on the forehead, and thin but prominent “horns” consisting of a crest made up of a pair of black feathers. Typically found in remnant patches of high-quality forest, but visits more disturbed habitat nearby, especially where fruiting trees are present. Found only on Ouvea Island off New Caledonia. Note distinctive voice: relatively low-pitched, nasal trumpeting notes, notably lower-pitched than the voice of Coconut Lorikeet.
Graceful Pitta
Erythropitta venusta
Rare and secretive jewel of the Sumatran highlands. Found at 400-1400 meters in wet forest, especially in gullies and ravines. Dark overall, with a rose-red belly and an electric-blue “eyebrow” and wing lining; in good lighting, note deep maroon on chest and back. Hops around quietly, foraging amongst the leaf litter and fallen debris. Song is a haunting machine-like whistle that begins and ends abruptly.
