Celebrating the Panamanian Golden Frog

By Mark Vassallo, curator of amphibians for The Detroit Zoological Society.

The Panamanian golden frog — or “La Rana Dorada” as it is known in Panama — is an iconic and potentially extinct amphibian from the elevations of the Central portion of the country. The golden frog, known for its bright yellow coloration and association with luck and fortune, has captured the hearts and spirit of the native Panamanian culture. On the upper reaches of “La India Dormida” or “Sleeping Indian” mountain in El Valle, Panama, there is a petroglyph that depicts a frog. This image has been estimated as originating before the 1400s and could represent one of the earliest tributes to one of the region’s most important animals.

El Valle, Panama is a gorgeous town nestled in the crater of an extinct mega volcano that has been dormant for more than 300,000 years. This fertile valley is home to a unique variety of plants and animals and is the former home of La Rana Dorada. El Valle is also the site for the annual Golden Frog Festival, which takes place in August. This event celebrates the golden frog with parades, concerts, educational displays and public offerings of support for this endangered amphibian. This year, I was fortunate enough to witness the events of this extraordinary week of festivities firsthand and was blown away by the pride and respect the Panamanian culture places on the golden frog and conserving the legacy tied to their heritage. 

Since 2015, I have represented the Detroit Zoo while traveling to Panama to assist the El Valle Amphibian Conservation Center Foundation (EVACC) in the establishment and upkeep of a bio-secure population of Panamanian golden frogs on the grounds of Hotel Campestre. This unique facility houses and breeds the golden frog and other threatened and endangered amphibians from Central Panama. The EVACC is a nonprofit organization run by Edgardo Griffith and Heidi Ross, a husband-and-wife team of biologists who have dedicated their lives to preserving the golden frog and the biodiversity of Panama. The EVACC foundation helps organize The Golden Frog Festival.

One of the first days of the event is a parade where all the local school children dress up like the golden frog — their attire is usually yellow with black spots mimicking the tell-tale markings of this cherished animal. As the procession starts, marching bands play, and the whole town comes to see the event. 

As the week progresses, the events include an evening of friendly competition between the various marching band troops from the area. In Panama, these marching bands are not your typical high school variety band. They incorporate stylish moves as they seamlessly mesh several varieties of music into the eye-catching display that brings sound and energy into the night. They wear special uniforms specific to their troop and continuously try to outdo one another with more incredible stunts and inspiring music as they proceed down the parade route to the church of San Jose. Here, the parade comes to an end.

Throughout the week, all people — from Panamanians to Dutch tourists — are allowed to pledge their support publicly through the signing of a mural that announces each person’s intent to preserve the golden frog — and, subsequently, the heritage of the Panamanian people who have inhabited this valley for thousands of years.

It is difficult not to be moved by such a display of national respect and acknowledgment for an amphibian. Coming from a background of zoo and aquarium science, I have seen how multitudes of charismatic megafauna have been widely celebrated and invested in, usually leaving the “little guys” like frogs to fend for themselves in a landscape dominated by “flagship” species like the panda bear or the blue whale. Amphibians are experiencing a crisis that is incomparable to any other taxa. Almost half of the Earth’s amphibian biodiversity is at risk or extinct. In the golden frog, there seems to be some hope for a representative that has comparable significance and also the potential to elevate the plight of amphibians into the public light.

The Panamanian culture has continued to hold the torch for this species, purely as a gesture of respect to the fantastic biodiversity that calls this country home. In celebrating La Rana Dorada, they also celebrate resiliency of a country that has chosen a frog as its champion, a golden frog. As one of the primary slogans of the EVACC foundation says, “salva lo que amas” or “save what you love.”

Polar Bear Denning: A Glimpse into Suka’s Cozy Retreat at the Detroit Zoo

Suka

Humans aren’t the only ones who enjoy cozying up inside when the fall chill takes over — so do some of the animals who call the Detroit Zoo home!

If you are visiting the Zoo this season, you may notice that Suka, a female polar bear, has not been as visible inside the Arctic Ring of Life habitat. But there’s no need to worry, her absence is for a heartwarming reason. This fall and winter, Suka will be nestled in her cozy den behind the scenes in hopes of welcoming a polar bear cub (or two!) into the world.

Last spring, Suka and her male counterpart, Nuka, were observed engaging in an important act of nature — breeding. This pair has successfully mated in the past, resulting in twins Astra and Laerke, who were born in 2020 and moved to the Point Defiance Zoo and Aquarium in June 2023. After their past success, experts with the Association of Zoos and Aquariums — an organization dedicated to animal well-being, conservation and the sustainable management of animal populations in human care — recommended that Suka and Nuka be paired together again. So far, all seems to be going well.

Suka and Nuka

It’s important to note that female polar bears will den whether or not they are pregnant. While we are hopeful Suka and Nuka’s union was successful, unfortunately, our staff has no way to confirm if Suka is indeed pregnant. Polar bear pregnancy tests don’t exist, and polar bear cubs are so tiny in the womb that they cannot be seen via ultrasound. Instead, our dedicated animal care team will be closely monitoring Suka for any subtle signs that might indicate an impending birth. We won’t know for sure if there are cubs on the way until November or December. 

To give this momma bear the best chance of success, Suka must remain undisturbed during her denning period. Denning is a critical phase in the life of a pregnant polar bear, where she seeks seclusion and tranquility to give birth and raise her cubs. Zoo staff is committed to providing Suka with a stress-free environment to ensure her comfort and well-being. Our team is hopeful that Suka will emerge from this denning season as the mother of some new cubs!

While Suka is cozied up in the bear den these next few months, visitors are encouraged to drop by and say “hi” to Nuka and the sea otters who call the Arctic Ring of Life home. And don’t forget to send Suka all your well wishes. 

Update as of January 2024: After months of rest and relaxation under the careful monitoring of our animal care team, Suka emerged from her den. Though we were hopeful for cubs, this was not the case. Suka is now acclimating to life outside the den and will not always be in sight. The team will monitor her closely to determine when she is ready to be reintroduced to male polar bear Nuka. We look forward to a winter full of polar bear fun with Suka and Nuka!
