The estate on which the Estancia stands reaches inside the marshlands. Hiking on the trails or taking a boat to reach Laguna Valle are two of the best ways to watch a large number of species, including the extraordinary black-masked finch (Coryphaspiza melanotis) that is so hard to find in the world, the streamer-tailed tyrant (Gubernetes Yetapa) and strange-tailed tyrant (Alectrurus risora). Additionally, on the wood fringes, one can find the sickle-wind nightjar (Eleothreptus anomalus), the black-and-white monjita (Heteroxolmis dominicana), and the bearded tachuri (Polystictus pectoralis).
