The Northernmost Record of the Least Grebe (Tachybaptus dominicus bangsi) in Baja California

Abstract

A specimen of the Least Grebe (Tachybaptus dominicus bangsi) from San Francisco de la Sierra, Baja Calfornia Sur, Mexico, collected 6 April 2022, was 36 km north of the oasis of San Ignacio, where the species breeds and site of the previous northernmost records on the peninsula. The bird’s occurrence on a small isolated pond yet coming into breeding condition highlight the species’ opportunism, possibly critical to its survival on the arid Baja California peninsula where freshwater oases suitable for the Least Grebe are few.
