SALDANA, Irwing S. et al. Bird diversity and noteworthy records from the western side of the Porculla pass and the Huancabamba-Chamaya river sub-basin, northwest of Peru. Arnaldoa [online]. 2020, vol.27, n.1, pp.191-220. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.271.27111.

Despite the great importance of the level of biodiversity and endemism that the Equatorial Seasonal Tropical dry Forest hosts, many of its areas remain unexplored. Here we present the results of the field evaluations carried out between 2014 and 2018 along the western side of the Porculla pass and the Huancabamba-Chamaya river sub-basin, in the northwest of Peru. this research is part of the dataset of the project Bird Assessments in Ecosystems of the Northwest of Peru - CINBIOTYC. We reported 174 bird taxa, belonging to 163 species and 32 families. Likewise, we reported two migratory bird species, one boreal and one austral, six endemics of Peru, and 31 restricted-range species, from which 25 belong to the Tumbesian Region, seven to the Marañón Valley and one was shared between them. We highlighted the record of four trans-Andean bird taxa, Amazilia amazilia leucophoea, Euphonia saturata, Basileuterus trifasciatus, and Pyrocephalus rubinus piurae, as well as, the remarkable records of Patagioenas oenops, Thamnophilus shumbae, Pachyramphus spodiurus, Turdus maranonicus, and Incaspiza ortizi.
