Abstract
I recorded the Least Grebe (Tachybaptus dominicus) for the first time in the state of Zacatecas on March 2012. Since then I have observed this species in different sites within the municipality of Nochistlán de Mejía, southwestern Zacatecas. Additionally, in May, July, September, and October 2014 four breeding sites were located in artificial ponds, one of them with a nest with three eggs. Artificial ponds, locally known as “bordos”, are important habitat not only for the Least Grebe, which is at the category of special concern according to the Mexican law NOM-059-SEMARNAT-2010, but also for other resident and migratory waterbirds such as ducks. Even when the Least Grebe has been recorded in the states of Aguascalientes and Jalisco, there is no information for the state of Zacatecas. In this paper, I report information about records, breeding sites, and behavior of this species in the municipality of Nochistlán de Mejía.

Keywords: Waterbirds, artificial ponds, Nochistlán de Mejía, southwestern Zacatecas.
