Resumen

We present new distributional records of two species of “red-breasted” meadowlarks of open grasslands and pastures in Colombia. The Red-breasted Blackbird S. militaris is recorded for the first time along the Colombian Amazon, where it probably arrived in the 1990’s following the establishment of cattle raising in the area. We report the Peruvian Meadowlark (S. bellicosa) for the first time from Colombia, from the Tumaco area of Nariño, and present observations on its behavior. We also report two specimens of this species from the same area taken 35 years ago, suggesting that this range extension is not recent but has been overlooked.
