adorable!
A little #throwback to some antics in the habituation enclosure! Red might not be the most attentive lemur, but Rose doesn’t seem to mind, especially when it comes to sharing bamboo!

So sad to hear of the loss of Pele, greatest athlete of the 20th century and the greatest footballer ever. I always wanted to meet him, but sadly never did. But I did see him play live, Santos vs São Paulo, in 1971

Lula won!!! What a relief for Brazil, for Amazonia, and for the world. It was close, but we’ll take it. Looking forward to a very positive and productive next four years.

The world depends on the Amazon for our climate, our biodiversity, and our lives. Marina Silva reminds us that Sunday all Brazilians can vote to protect the environment.
Ao longo dos anos, muitos brasileiros que vivem longe da Amazônia me perguntaram: "o que posso fazer pela Amazônia?". Neste domingo temos uma resposta clara. Você pode votar!

The Brazilian state of Mato Grosso is excellent for primate-watching.  With 29 species, including two recently described endemics (Schneider's Mt sharmoset, Mico schneideri) and the Mato Grosso Titi Monkey (Plecturocebus grovesi), it should be high on your list to visit

Happy #ReptileAwarenessDay! According to the @IUCNRedList, at least 21% of all reptile species globally are threatened with extinction. Today, we celebrate conservation heroes who work to save these often misunderstood cold-blooded vertebrates. Learn more→bit.ly/3z0m313

Congratulations to the authors of this description of a new titi monkey species (Cheracebus) from Peruvian Amazonia, very appropriately named after our good friend and pioneer of Peruvian primatology, Rolando Aquino. andina.pe/agencia/noticia-co…

Independence Day in Brazil.  Happy 200th anniversary of independence from Portugal (September 7, 1822). Very pleased to be in Brazil on this historic day.  Here Brazilian schoolchildren raising the flag at Jofre Velho, in the Pantanal region of southern Mato Grosso state.
