The day starts with a surprise with the confirmation of another new record for Madidi, the Yates little big-eared bat (Micronycterus yatesi) previously known from the tropical dry forests of southern Bolivia. Dr. Lizette Siles ought to know this species as she recently described it in 2013, but this record represents a significant northern range extension. Another registered bat is perhaps the most visually striking to date for Identidad Madidi, the white-throated round-eared bat bat (Lophostoma silvicolum) with extraordinarily elaborate ears. Our ichthyologist team returns from the Ubito River with at least nine previously unregistered species pushing the total number of vertebrate species registered at this site so far to 220 including at least 15 new records for the park.
