American Dipper at Rio Labú (BOSAWAS)

From April 30 to May 8, 2012, Georges Duriaux and Liliana Chavarria undertook an eight-day expedition along the Rio Labú into the heart of the Saslaya National Park, part of Nicaragua's massive BOSAWAS reserve.  The trip produced a number of impressive bird species, including Black-eared Wood-Quail (Odontophorus melanotis), White Hawk (Leucopternis albicollis), Solitary Eagle (Harpyhaliaetus solitarius), Ornate Hawk-Eagle (Spizaetus ornatus), Crested Owl (Lophostrix cristata), Black-crested Coquette (Lophornis helenae), Yellow-eared Toucanet (Selenidera spectabilis), Scaly-throated Leaftosser (Sclerurus guatemalensis), Striped Woodhaunter (Hyloctistes subulatus), Long-tailed Woodcreeper (Deconychura longicauda), nine species of antbirds including Wing-banded Antbird (Myrmornis torquata), Golden-crowned Spadebill (Platyrinchus coronatus), Thrush-like Schiffornis (Schiffornis turdina), Song Wren (Cyphorhinus phaeocephalus), and White-throated Shrike-Tanager (Lanio leucothorax).

One of the most noteworthy discoveries, however, was a seemingly healthy population of American Dipper (Cinclus mexicanus), a bird that, although found in fast-flowing mountain streams in Costa Rica and Panama, had not been recorded in Nicaragua since Richardson collected three specimens near San Rafael del Norte (Jinotega) in March 1892.  George and Lili recorded this species on five separate days in several locations along the river, with a daily high of three individuals recorded on May 2 at the campsite they designated "Labú 2".
