Black and Green or Green and Black

Green and Black Poison Dart Frog: Frog Heaven, Sarapiqui, Costa Rica, March 2025 — Much like Zebras, there might be some debate as to whether this poison dart frog is more green on black or black on green…but the official name is Green and Black. It is, even more officially, Dendrobates auratus. They are in the same family as the bright red and blue Strawberry (or Blue-jeans) poison dart frog, but a different species. They are slightly larger as well as being, of course, about as totally a different color as you can get. 🙂 Sony a6700. Tamron 50-400 at 265 and 463mm equivalents. By the light of my Ulanzi Photo Flashlight (and led light not a flash), using my little travel tripod. Aperture preferred program with my macro modifications. f16 at 1/30th. Processed in Photomator.

Red-eyed Leaf Frog

Red-eyed Leaf Frog: Frog Heaven, Sarapiqui, Costa Rica, March 2025 — The Red-eyed Leaf Frog is probably the poster child for Costa Rican conservation…and maybe for Central American Conservation, or even Rainforest Conservation. It is just such a stunning subject for photography, with its unlikely combination of bright colors and quirky looks, and is the one non-bird species that almost every photographer who visits Costa Rica wants to photograph. Now I am going to tell you that almost every photo you have ever seen of a Red-eyed Leaf frog was posed. It is possible to find them, around the decorative pool at Selva Verde Lodge, or just out in the Rainforest, where they can be photographed “in situ” so to speak, but those are not the photographs you have likely seen. The folks at Frog Heaven brought this frog in to their little photo shelter in the rainforest and placed it on the woody vine for us to photograph. No flash was used, nor is flash allowed. These were taken by the gentle light of my made-for-purpose hand-held led. The folks at Frog Heaven are very careful in handling the wild fogs…it is their business…and they truly care about the wellbeing of the frogs on their property. No harm was done, but the frog’s night was disrupted. I do have mixed feelings about that…but these are without doubt my best photos to date of Red-eyed Leaf Frogs. I offer them as an incentive to protect the rainforest, as the people at Frog Heaven do every day…without photographers eager to photograph frogs and the skill of the Frog Heaven workers, and the vision of the owners, this property would be what it was a generation ago…just another banana plantation on the river. Sony a6700. Tamron 50-400 at 600mm equivalent. My macro modifications to Aperture Preferred Program. f14 and f20 for increased depth of field. -1 to -2 EV to balance highlights and shadow under the artificial light.

Red-eye

Red-eyed Leaf Frog: Frog Heaven, Sarapiqui, Costa Rica, December 2024 — No visit to the lowlands of Costa Rica would be complete without an encounter with the Red-eyed Leaf Frog…perhaps the most emblematic of non-bird species in the American Tropical Rainforest. I already posted shots from my first daylight encounter with this frog, and of course I had to ask the guide at Frog Heaven to find me one before we were done there. Taken in the light of my Ulanzi Photo Flashlight and from a light-weight travel tripod. Sony a6700. Tamron 50-400 at 382mm. Aperture preferred with my macro modifications. ISO 12800 @ f16 @ 1/15th. -1.3EV Processed in Photomator.

Splendid!

Splendid Leaf Frog: Frog Heaven, Sarapiqui, Costa Rica, December 2024 — I posted a photo of this Splendid Leaf Frog while I was still in Costa Rica in December and told the story of Frog Heaven’s efforts to entice the frog back to their property after it’s nesting tree blew down. They discovered that for it to thrive it needs an elevated spawning pool that has been “poisoned” for other frogs by the secretions of the host tree. No really, poisoned. The tree releases a toxic compound into the water that kills the tadpoles of other species of frogs, but not the tadpoles of the Splendid Leaf Frog. (I am not sure what the frogs do for the tree in return…if anything.) At any rate, Frog Heaven installed 50 gallon drums well off the ground and put cut branches of saplings of the host tree to soak in the water…and the Splendid Leaf Frog has returned. And Splendid it is. Just look at those colors. Taken by the light of my Ulanzi Photo Flashlight. Sony a6700. Tamron 50-400 at 327mm equivalent. Aperture mode with my macro modifications. f11, -1.7 EV, ISO 12800. Processed in Photomator.

Smoky no more

Savage’s Thin-toed Frog: Frog Heaven, Sarapiqui, Costa Rica, December 2024 — This used to the Smoky Jungle Frog…just way better than Savage’s Thin-toed Frog. Way better! Therefore I will continue to call it the Smoky Jungle Frog, thank you just the same! Fascinating creature by any name. We found this one right beside the trail at Frog Heaven, not at all bothered by our flashlights. I love the natural look of the light from my Ulanzi Photo Flashlight! Sony a6700. Tamron 50-400 at 327mm equivalent. My macro modifications to Aperture preferred mode. f16 at 25600 ISO. Processed in Photomator. (Gotta love the colors at this high ISO on the a6700.)

Glass Frog

Fleischmann’s Glass-Frog (I think): Frog Heaven, Sarapiqui, Costa Rica, December 2024 — I asked our guide at Frog Heaven to find me a glass frog. Glass frogs are a family of frogs with semi-transparent skins so that you can actually see the organs inside. He came back with the smallest, tiniest glass frog I have ever see. Cute. This guy was less than 1/2 inch tall. The best I can do on an id is Fleischmann’s…which is likely as they are pretty common in Costa Rica. Just generally much bigger. Sony a6700. Tamron 50-400 at 120mm equivalent. Aperture preferred program (my macro modifications) at f16, -2.7EV, ISO 25600 at 1/15th. In the light of my Ulanzi Photo Flashlight. Tripod.

Daylight Frog

Red-eyed Leaf Frog: Pierella Ecology Gardens, Sarapiqui, Costa Rica, December 2024 — This is my first ever daylight shot of a Red-eyed Leaf Frog. If you can call a rainy day under the rainforest canopy daylight. 🙂 Our guide found the frog for us, and moved it to this little twig for photos…so, I do feel that it was cheating a bit…but I sill like the image…and love the critter. 🙂 Sony a6700. Tamron 50-400 at 250mm equivalent. Program mode with my bird and wildlife modifications. (ISO 25600! Even in daylight I could have used more light.) Processed in Photomator.

Costa Rica! Splendid!

Splendid Leaf Frog: Frog Haven, Sarapiqui, Costa Rica, December 2024 — Not your typical Costa Rican Leaf Frog shot…which are generally the Red-Eyed Tree Frog. The Splendid Leaf Frog is more rare, especially this far north in Costa Rica. It is much more common in Columbia and Ecuador. Frog Haven have installed a water barrel with in which they soak branches of a local toxic plant, to create an environment in which only the tadpoles of Splendid Leaf Frog can thrive. After a long absence they are coming back to the area. This is a juvenal male. Sony a6700 with Tamron 50-400 Di3 at 162mm equivalent. My Ulanzi photo led flashlight. Program mode with my macro modifications. ISO 12800 @ f16 @ 1/25. -1.7EV

Costa Rica! Frog different

Rosenburg’s Tree Frog (?): Macaw Ranch, Sarapique, Costa Rica, December 2023 — Of course, the Red-eyed Leaf (or Tree) Frog is not the only amphibian of the Sarapique rainforest. We found this brown species in a bush near the ranch house at Macaw Ranch. Tree Frogs are very rare in the daylight. I think it might be a Rosenburg’s.

Costa Rica! More frogs

Red-eyed Leaf Frogs: Selva Verde Lodge and Reserve, Sarapiqui, Costa Rica, December 2023 — Part of what makes Red-eyed Leaf Frogs so much fun to photograph is the interesting poses they take and hold. We don’t pose them. This is the way we find them, caught in the act of being themselves. 🙂 OM System OM-1 with ED 100-400mm IS zoom at 800mm equivalent. Program mode with in-camera focus stacking.
