IPBio received a grant for audio equipment and software, namely Song Meter SM4 and Song Scope, from Wildlife Acoustics.


IPBio captures high quality recording of wildlife which are stored in our sound bank. These recordings allow us to understand in greater detail species composition, distribution, habitat use, behavioral patterns and peak periods of activity.



Leptodactylus flavopictus

Audios were recorded for a period of one year at a breeding site of Leptodactylus flavopictus, a species considered rare that is endemic to the Atlantic Forest. This was the second vocalization ever recorded of this species since its discovery. In collaboration with Dr Luis Felipe Toledo of UNICAMP and his students, we are analyzing the audios to trace the seasonal activity pattern of the species, to describe the months in which the species is active, and to evaluate the profile of daily activity.

Leptodactylus notoaktites

In June 2018, we received an intern, Kelsey Higney, from the University of Antioch, New Hampshire, who took the time to map the vocalizations of three frog species during a year of data collection to understand their seasonal variations. One of these species was Leptodactylus notoaktites, which is endemic to the Atlantic Forest.


nudicolli proknia

Procnias nudicollis, popularly known as araponga, is considered “vulnerable” due to habitat destruction and the illegal trade in wild animals. This magnificent bird attracts a lot of attention from traffickers due to its beauty and vocalization. In 2018, David Atch, a volunteer from Israel, studied the species' seasonal activity patterns, plotting its most intense periods of activity.
