Abstract
Serpophaga hypoleuca P.L. Sclater & Salvin, 1866, is a bird species distributed in northern South America, where it mainly inhabits shrubs on river islands and occasionally large river shores. Its distribution is not well known in Colombia where current records show the species present south of the Amazonas department and locally in Arauca and Vichada. We present a new locality in Colombia along the Guaviare River, in San José del Guaviare, which expands the known distribution of this species in Colombia, filling an information gap for the Guaviare region.

We present a new locality in Colombia along the Guaviare River, in San José del Guaviare, which expands the known distribution of this species in Colombia, filling an information gap for the Guaviare region
The records presented in this study were made along the Guaviare River in an area known as Buena Vista, in the Guaviare department, eastern Colombia
We observed other individuals on 04 Nov. 2019, perched on T. integrifolia shrubs along with individuals of Sporophila castaneiventris Cabanis, 1849, and S. bouvronides (Lesson, 1831) on a beach along the Guaviare River, 1 km upstream (02°35′N, 072°39′W, 180 m a.s.l.) from the previously described locality. These records confirm the presence of Serpophaga hypoleuca year around along the beaches of the Guaviare River, and expand the known distribution of this speciesin Colombia
Summary
In Venezuela, this species is found in seasonally flooded savannahs with thickets, near the Apure, Meta, and Orinoco rivers. It can be found near few lakes and bushes-gamelot lands along the lower section of the Orinoco River (Meyer de Schauensee and Phelps 1978; Hilty 2003; Lentino et al 2018; Navarro-Rodríguez et al 2018). Serpophaga hypoleuca venezuelana is distributed along the Orinoco River and its tributaries in the extreme east of Colombia and central Venezuela. Serpophaga hypoleuca pallida distribution includes the lower sections of the Amazonas, Tapajos and Tocantins rivers
