A series of ephemeral saline lakes that form in the area to the east of Loma Plata have been declared an 'Important Bird Area' because of their importance for migrating birds. Though individual lagoons may be dry for several years before filling after a good rainstorm, the birds somehow find them. They are best from May to September when flocks of exotic ducks and flamingos obscure the water. From October to December and March to April they are used by waders on passage.
One accessible place to visit is Laguna Capitán. The lagoons are often dry here but the surroundings teem with wildlife. For waterbirds and particularly flamingos, head to Campo Maria, which usually has water and is a great place to see mammals such as tapirs and peccaries.
