TL;DR: A new species of Micrastur (forest-falcon) from the rainforests of Brazil and adjacent northeastern Bolivia is described, which has a vocal repertoire that differs from those of congeners and exhibits subtle yet consistent morphological distinctions that distinguish it from all other forest-falcons.
Abstract: I describe a new species of Micrastur (forest-falcon) from the rainforests of Brazil and adjacent northeastern Bolivia. Initial detection of the cryptic new taxon was enabled through hearing its distinctive voice, notably different from any of its congeners. Several specimens of the undescribed species subsequently were located in several museums; because the new species closely resembles M. gilvicollis (Lined Forest-Falcon), these specimens had remained unrecognized for more than a century. The new taxon not only has a vocal repertoire that differs from those of congeners, M. gilvicollis, M. plumbeous (Plumbeous Forest-Falcon), and M. ruficollis (Barred Forest-Falcon), but it also exhibits subtle yet consistent morphological distinctions that distinguish it from all other forest-falcons. This elusive raptor inhabits humid terra firme forest in southeastern Amazonia, and a disjunct population exists in the Atlantic rainforests of eastern Brazil (the latter known only from historic specimens) and ...

TL;DR: The genus Micrastur contains six species of small to medium-sized falconids, all of which inhabit forests from southern Mexico to central Argentina, and there is little information on the reproductive biology of these species.
Abstract: The genus Micrastur contains six species of small to medium-sized falconids. All are long-tailed, shortwinged, and inhabit forests from southern Mexico to central Argentina (Brown and Amadon 1968). There is little information on the reproductive biology of these species. The nest and young of only one species, the Collared Forest-Falcon (M. semitorquatus), has been described and that from only one breeding pair (Mader 1979). A captive Collared Forest-Falcon at the National Zoological Park laid two eggs in 1968, one of which was salvaged (Wetmore 1974). T. de Vries (pers. comm.) found a pair of Barred Forest-Falcons (M. ruficollis) going in and out of a hole, which he believed was a nest, in the top of a large tree near the forest edge. Other than these reports, the description of nests, eggs, or young of the remaining congeners are unreported (Thiollay 1985).

TL;DR: A new species of chewing louse is described from a series of lice collected in Peru from Micrastur ruficollis zonothorax, the barred forest-falcon.
Abstract: Colpocephalum holzenthali, a new species of chewing louse, is described from a series of lice collected in Peru from Micrastur ruficollis zonothorax, the barred forest-falcon. Colpocephalum holzenthali is most similar to members of the Colpocephalum polybori species group.
