Papyrus Gonolek
Laniarius mufumbiri
Boldly patterned black-and-red bushshrike with a yellow crown and pale eyes. The duller immature has orange underparts and a gray crown. Found in papyrus swamps, where it skulks with great skill. The male gives ringing “chonk” or “chuwee” notes, often in rapid-fire or up-and-down series. The female gives a low ratcheting call which is sometimes given in a duet alongside the male’s vocalizations. Similar to Black-headed Gonolek, but has a yellow crown and a white wingbar.

行为
This species is difficult to observe and has been little studied. It occurs singly or in pairs in papyrus swamps, lurking among the vegetation and only flying occasionally, usually a short distance over water to another patch of papyrus. Its presence can often be detected by its calls, which consist of brief whistles and grating tearing sounds which have been rendered as "U-tzeu-U-tzee". Sometimes two birds duet. The diet consists mainly of insects such as beetles, flies and ants, but also includes snails, fruit and seeds when available. Little is known of its breeding biology, but the nest is probably built in a small bush in reedbeds.

Puna Thistletail
Asthenes helleri
Small brown bird with a very long, thin tail. Found in elfin forest and montane scrub around and above the treeline, where it forages singly or in pairs low in dense vegetation. Does not overlap with other thistletail species, and its distinctive tail shape distinguishes it from any other bird in range. Its song is a fast, slowly rising chatter of sharp, squeaky notes.
Sooty Tern
Onychoprion fuscatus
This tropical seabird is distinctive among terns with its jet-black back, black cap, and neat white forehead. Immature birds are entirely dark blackish with white spots on wings and a white undertail. Most similar to Bridled Tern, but darker black back, dark undersides of flight feathers, and narrower white edges on tail. Sooty Tern is found in warm tropical waters worldwide. It breeds in colonies on sandy islands, but otherwise usually stays far offshore, and is rarely seen near land except when blown off course by a hurricane.
Yellow-breasted Fruit-Dove
Ptilinopus occipitalis
A medium-sized dove of lowland and mid-elevation forest canopy. Distinguished by green upperparts, tail, thighs, and sides, gray crown and sides to the neck, yellow breast, maroon patch on the belly, and maroon stripe from the eye around the back of the head. Similar to Flame-breasted Fruit-Dove, but has a yellow rather than orange chest and pale gray in front of the eyes. Song is a deep, downslurred “woo-oo.”
