Olrog's Cinclodes

Cinclodes olrogi

Large terrestrial Furnariid endemic to rocky hillsides and rushing streams of the Sierra de Comenchingones in central Argentina. From similar White-winged Cinclodes by Olrogs’ light brown (not white) bases to primary coverts, and darker chest contrasting markedly with white throat.

Identification

Olrog's cinclodes is about 17 cm (6.7 in) long and weighs 24 to 32 g (0.85 to 1.1 oz). It is a small cinclodes with a medium-length slightly decurved bill. The sexes have the same plumage. Adults have a white supercilium, and blackish brown lores and ear coverts. Their crown is blackish brown and their upperparts dark gray-brown with a chestnut tinge. Their wings are a darker gray-brown with a wide white band across the base of the flight feathers. Their tail is dark gray-brown with dull rufous tips on the outer feathers. Their throat and breast are white with some dark scaling on the latter. The rest of their underparts are pale dull brown.

Taxonomy

Olrog cinclodes' English name and specific epithet honor the Swedish-Argentine biologist Claes C. Olrog.<p>One of the authors who first described Olrog's cinclodes (Nores) later treated it as a subspecies of what was then called the bar-winged cinclodes (C. fuscus sensu lato). (In a three-way split of the bar-winged that began in about 2009, C. fuscus was renamed to the present buff-winged cinclodes to avoid confusion with the previous much more complex species.) The species' namesake Olrog and several other authors maintained that it was more closely related to the gray-flanked cinclodes (C. oustaleti), and this has been confirmed by genetic data.<p>Olrog's cinclodes is monotypic.

Arctic Tern

Arctic Tern

Sterna paradisaea

Elegant seabird with extremely long wings and forked tail. Adults are pale gray with white cheek, black cap, and red bill and legs. Very similar to Common Tern; note shorter bill, shorter legs, gray belly, and paler gray wingtips with very limited dark tips. Young birds show partial black cap and black bill and legs; look for pale gray wingtips and stubbier legs to separate from Common Tern. Rarely seen away from breeding grounds on coastal islands or small ponds in the Arctic tundra. Migrates offshore, heading for wintering grounds in Southern Hemisphere.

Red-naped Fruit-Dove

Red-naped Fruit-Dove

Ptilinopus dohertyi

A large, striking fruit-dove with a dark lower body, a cream-colored head, and a diagnostic conspicuous red patch on the nape. Juveniles show yellow fringes to upperparts feathers and greenish feathers on head and breast. Usually encountered singly or in pairs in the upper levels of forest in lowlands and hills.  Call is a low, disyllabic “wooo-hoo,” usually given repeatedly.

Streaked Berrypecker

Streaked Berrypecker

Melanocharis striativentris

A fairly small, rare bird of mid-montane forest interior. Mainly olive color with some streaking on the underparts, an indistinct, broad eye-ring and orange around the base of the bill. Forages for fruit in the midstory where it is inconspicuous. Normally occurs above the level of Black and Obscure Berrypeckers and is stockier and shorter tailed than Mid-mountain and Fan-tailed. It is the only berrypecker to have streaking on the underparts. Voice, a harsh, scratchy call.
