TL;DR: In this paper, the authors present new distributional information on 36 avian species of the cloud forests and paramos of this region (1300-3250 m), gained through eight years of fieldwork and general collecting.
Abstract: Northwestern South America is a complex area that has witnessed the differentiation and expansion of a major portion of the Neotropical avifauna. The northern end of the Cordillera Central of the Colombian Andes contributes to this complexity by bringing a continuum of humid habitats from the Andean highlands to the lowland rainforests. We present new distributional information on 36 avian species of the cloud forests and paramos of this region (1300–3250 m), gained through eight years of fieldwork and general collecting. These new records reflect the mixed biogeographic affinities of the avifauna of the northern Cordillera Central, which is composed of taxa from the pluvial foothills of the Choco (e.g., Indigo Flowerpiercer [Diglossa indigotica], Scarlet-and-white Tanager [Chrysothlypis salmoni]), Central America and Darien (e.g., Purple-throated Woodstar [Calliphlox mitchellii]), and elsewhere in the Andean mountains (e.g., Semicollared Hawk [Accipiter collaris], Yellow Manakin [Xenopipo flavic...

Abstract
Multiple molecular phylogenetic studies have demonstrated that two Neotropical raptors, tiny hawk Accipiter superciliosus and its sister species semicollared hawk A. collaris, are not closely related to core Accipiter, and that A. superciliosus, at least, possesses osteological characters not replicated in the remainder of the genus. Based on these data, there is a need to recognise their distinctiveness at generic level. However, as recently noted in two global bird checklists, no name is available to accommodate them, so we provide a new nomen here. Furthermore, two Asian accipitrids, crested goshawk A. trivirgatus and its presumed closest relative Sulawesi goshawk A. griseiceps, are also phylogenetically distinctive; in this case the genus-group name Lophospiza is applicable. We also designate type species for two genus-group names (Hieraspiza and Eusparvius) currently in the synonymy of Accipiter, and, as an aid to future workers, we provide a synonymy of the genus Accipiter and a list of species currently included in Accipiter for which published molecular phylogenetic data are apparently lacking.
