On this episode of the Mongabay Newscast, we’re thrilled to feature a conversation with the one and only Paul Simon, who's just announced a tour in support of the environment. The 12-time Grammy-winning musician recently announced on Mongabay.com that he is embarking on a 17-date US concert tour, with all proceeds benefitting Half-Earth, an initiative of the E.O. Wilson Biodiversity Foundation.

We play parts of the interview with Paul Simon as he discusses his long-time friendship with E.O. Wilson, the power of optimism, and why Dr. Wilson’s Half-Earth idea inspired him to get involved.

Also on the program, we round up the top conservation news and feature another Field Notes segment, this time with Zuzana Burivalova, a conservation scientist at Princeton University who has recorded the soundscapes of over 100 sites in the Indonesian part of Borneo. We listen to a variety of those recordings, each made in a different type of habitat, from protected rainforest to an oil palm plantation, and Burivalova explains what we’re hearing — and in some cases, what we’re not hearing.

On this episode of the Mongabay Newscast, we welcome contributing editor Glenn Scherer to the program, who is responsible for Mongabay’s “Almost Famous Animals” series, which just wrapped up its second year with a focus on little-known Asian wildlife.

Many conservationists argue that protecting charismatic species like tigers, rhinos, and orangutans will also lead to the protection of less widely known species such as pangolins and langurs, but that has not always been the case. Many lesser known species often fall through the cracks, so this series aims to raise their profiles.

And in the Field Notes segment, Luca Pozzi discusses a new genus of galagos, or bushbabies, found in southeastern Africa that he helped discover. We'll play some calls made by galagos in the wild, and Luca explains how those recordings aid in our scientific knowledge about this kind of wildlife.
