Charles and Jon are joined by Claudia Diaz, from Wild About Colombia, at her home in Bogota.

Claudia and Robin Smith founded Wild About Colombia in 2017 and the company quickly developed a reputation for high quality and adventurous mammalwatching trips.

Claudia talks about a career which has taken her from marine biology in Mexico's Gulf of California back to her native Colombia, via studying conservation in the UK. She describes her passion for involving local communities in ecotourism and runs through some of the particular difficulties she and Rob faced in bringing not just ecotourism, but mammal tourism, to a country emerging from 60 years of conflict. From navigating travel insurance company red zones to trying to persuade birding guides that some clients prefer to walk past megabirds (some clients like Jon for example), she describes a challenging but rewarding journey through an extraordinary country.

Notes: There are several trip reports featuring Wild About Colombia on mammalwatching.com including reports from Jane Kempler, Venkat Sankar and Jon.

Charles talked about a New York Times article on freeze dried bats which is here (though it is behind a firewall).

Dr Charles Foley is a mammalwatcher and biologist who, together with his wife Lara, spent 30 years studying elephants in Tanzania. They now run the Tanzania Conservation Research Program at the Lincoln Park Zoo in Chicago.

Jon Hall set up mammalwatching.com in 2005. Genetically Welsh, spiritually Australian, currently in New York City. He has looked for mammals in over 110 countries.

Charles and Jon talk to Dr Barbara Taylor (USA) and Dr Lorenzo Rojas-Bracho (Mexico), who together lead the global efforts to save the Vaquita from extinction.

The Vaquita, a tiny and beautiful porpoise, is found only at the top of the Gulf of California and holds the unfortunate distinction of being the world's rarest marine mammal (possibly the rarest of any mammal species). There may be as few as 6 animals left alive.

The story of the Vaquita's precipitous decline from its discovery in 1958 is as tragic as it is complex. In a fascinating conversation we learn about the Vaquita's biology and how gillnetting has driven the species to the very edge of extinction. We also discuss why illegal fishing - fueled by organized crime and a demand in East Asia for the swim bladder of the Totoaba fish - is so difficult to prevent. But Barb and Lorenzo offer some optimism for the future: there may be more Vaquitas hiding in the Gulf of California and it is not to late to save the species.

Notes: There is a lot more information online.

Viva Vaquita is a coalition of scientists, educators and conservationists who strive to increase attention on the Vaquita. They host an International Vaquita Day every year to update folks on the latest situation.

There are several documentaries about the Vaquita story including Sea of Shadows which you can find here https://www.vaquitacpr.org

The IUCN's Cetacean Specialist Group website has all recent Vaquita survey reports (with 2024 coming soon) as well as reports from the recovery team (CIRVA).

If you would like to help save the Vaquita you can donate money to - or volunteer to join - Sea Shepherd the conservation society who are doing very important work in the Gulf of Mexico to help tackle the illegal fishing that is killing the species.

If you want to check whether the seafood you eat is sustainable then you can visit Seafood Watch even if they do not as yet carry information about the fisheries that most impact the Vaquita.

Jon's report on joining the 2024 Vaquita Survey with Barb and Lorenzo is here.

Finally here is the Guardian article on the 6 million antelope migration in South Sudan that Charles mentions at the start.

Charles and Jon talk to Australian author, broadcaster and wildlife nut Bradley Trevor Greive (BTG) from his home in California.

BTG has an extraordinary CV: he was a paratrooper and cartoonist before becoming a successful author and broadcaster. In between he found time to win the French Polynesian Rock Lifting Championship, graduate from the Russian Cosmonaut Space Program, spend 6 years working on Brown Bears in Alaska and still practice on his ukulele. And he devotes considerable energy to supporting conservation work around the world. As you might imagine we had plenty to talk about.

In an entertaining hour Bradley talks about some of his formative experiences with wildlife as a child living around the world, his research work with the enormous Brown Bears of Alaska's Alexander Archipelago, and some of the many painful encounters he has had with wildlife along the way. He has plenty of useful advice that every mammalwatcher needs to hear. For instance you will learn what not to wear if you don't want a flying fox to ejaculate into your ear, and what not to do if it happens anyway.

Notes: read BTG's Wikipedia page and you will almost certainly be familiar with some of his work. From his 'The Blue Day Book' to the (really very lovely) Penguin Bloom book and movie on Netflix. He provided several of the voices on Finding Nemo and his new show Queer Planet launched on Peacock in June 2024. You can follow him on Instagram @Tasmanian_Grizzly
