If you’ve been following our work, you might already know Deborah – a two-fingered sloth we’ve been tracking through the Urban Sloth Project for several years.

In 2019, wildlife photographer Andres Espinoza captured something astonishing in Manuel Antonio National Park: a wild adult male sloth carrying a baby.

It’s hard to believe we’re already heading into the fifth month of the year—while sloths may be slow, time certainly isn’t!

Today we celebrate books! April 23rd is International Book Day, in honor of two of the most important writers in history: William Shakespeare and Miguel de Cervantes.

It’s April 22nd, Earth Day, although we believe all days are Earth Day. We don’t want to write another blog about the importance of having a livable planet.

We’re thrilled to share that SloCo’s work, featuring Dr. Rebecca Cliffe and our Project Manager Tamara, is highlighted in the latest episode of In Her Nature, a PBS documentary series.

To celebrate the International Day of Human Spaceflight, held every April 12th, we're reaching for the stars with a little help from one of our most stellar supporters: Ponder E. Stine.

Last week, something truly extraordinary happened in the South Caribbean of Costa Rica: a three-fingered sloth baby with leucism was spotted! This is the first case ever recorded of its kind.

It’s been one of the rainiest months of the year so far, but soggy boots and muddy field kits didn’t slow us down one bit.

One of the most rewarding parts of our work is seeing sloths and other wildlife actually using the Sloth Crossing canopy bridges that we have built.

We donated five Sloth Crossing canopy bridges to help reconnect fragmented forest habitats in Mata de São João, Bahia, Brazil, home to the rare and endangered Northern Maned Sloth (Bradypus torquatus).

Sloths and pandas are two beloved, yet vastly different animals from opposite sides of the world. Their uniqueness has captured the hearts of many, and their distinct appearance and quirky behavior have become symbols of nature’s diversity and resilience. Sloths are known for their slow pace and leisurely, arboreal lifestyle, while pandas are recognized for their black and white coats, clumsiness, and love for bamboo.

February flew by in a blur of new sloths, record-breaking census days, and even a little Italian TV fame! But before we dive headfirst into March, let’s take a moment to look back at all the jungle excitement.

Last week, we went to the primary forests in search of new sloths to collar and monitor for the Urban Sloth Project.

The Week of Love might be coming to an end, but the love for sloths is endless. And we ask the same question: Why are sloths loved worldwide? We tried to answer this question in this blog over here. 

January always feels like the longest month, and this one was no exception – five whole weeks!

The rainforests of Central and South America are home to some of the most fascinating creatures on Earth, including sloths and howler monkeys.

Tender is no ordinary sloth. He’s a young, sweet explorer living near a beach bar in Costa Rica’s South Caribbean. But his story starts with someone equally extraordinary: his mother, Tiki.

As December sneaks up on us, we are diving into our year-end reflections (and annual reports – yes, we have to prepare more than one!). Looking back, we’re incredibly proud of all that we’ve accomplished in 2024, and we’re already setting our sights on new goals for 2025 with our upcoming strategic plan.
