First records of Red-eyed Thornbird Phacellodomus erythrophthalmus ferrugineigula and Pale-breasted Thrush Turdus leucomelas for Uruguay

摘要

We report two new resident species for north-west Uruguay based on surveys c.20 km south-east of Rivera city, between the Cuchilla de Santa Ana in the north-east (the Uruguay/Brazil border) and Cunapiru stream in the south-west, dpto. Rivera. Naturalhabitats include campo grasslands, gallery forests and other riparian habitats along the main watercourses, cliff forest at the base of tablelands and plateaux, and isolated patches of swamp forest. Main economic activities are traditional cattle ranching and forestry. Between 22 February 2001 and 2 March 2002 we conducted biodiversity surveys of lands owned by the forestry company COFUSA, which operates c. 50,000 ha of Eucalyptus and Pinus plantations, most of them younger than 20 years old. We surveyed birds by direct observation, sound-recording, mist-netting and collecting, during ten trips totalling 37 days. Specimens are deposited in the Museo Nacional de Historia Natural y Antropologia (MNHN) in Montevideo.
