Bamboo Warbler
Locustella alfredi
Mid-sized warbler with a long tail. Dark brown overall, with a white throat and pale eye-line. Found very locally in middle-elevation habitats with a dense ground cover, including bamboo, forest, marsh, and lush grassy areas. Rare species that is not often seen. Most likely to be detected and identified by its distinctive song: a ratcheting up-and-down “dee-ka dee-ka dee-ka…” series which can last for several seconds. Very similar to Evergreen-forest Warbler, and best distinguished by its different song.

Thicket Tinamou
Crypturellus cinnamomeus
A furtive, ‘tail-less’ gamebird that lives on the ground in tropical woodland and forest. Rarely seen (sometimes crosses quiet roads or trails), but haunting whistled song is often heard, especially early and late in the day. Note distinct pale barring on upperparts and bright reddish legs. Birds in West Mexico are paler and grayer overall, those in East Mexico and Central America have a rusty-colored breast and belly.
Cocos Tyrannulet
Nesotriccus ridgwayi
Small and drab flycatcher found only on Cocos Island, which is located in the Pacific Ocean about 300 miles southwest of mainland Costa Rica. Most birds are brown above with a buffy belly, with tan wingbars and a pale eyebrow. Some individuals have a brighter yellow belly or an olive-tinged back. Inhabits humid forest as well as scrubby and swampy areas, often in dense vegetation. Typical song is a short, descending sputter.
Morotai Friarbird
Philemon fuscicapillus
A large gray-brown honeyeater with a long, powerful dagger-shaped bill and pink bare skin around the eye. Paler on the underparts. Singles or pairs inhabit canopy of forest, forest edge, and plantations in the lowlands. Similar to the entirely brown Halmahera Oriole by the bare skin around the eye. Bill shape also different, with a sharper, finer point to the bill on the friarbird. Gives a fluty, oriole-like song with repetitive “chewit-woow” phrases. Also gives a harsh “ker” alarm note.
