Clearwing butterflies, also known as glasswings, have transparent wings. But against all that green background, this guy appears to have blue in the transparent parts. Photographed in the El Valle highlands of Panama. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/200th of a second.

I’ve identified this guy as a Canal Zone tree frog, but also seems to go by the red-webbed tree frog. Either way, it was photographed at night in the town of El Valle in Panama. Nikon D810 with Nikkor 105mm macro lens, ISO 200, f/14 at 1/60th of a second, two Nikon SB-900 flash units.

Not the prettiest agouti I’ve ever seen but who am I to comment on the relative attractiveness of Central America rodents. I photographed this one enjoying breakfast in Soberania National Park in Panama. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 1600, f/4 at 1/125th of a second.

I love toucans. To me, they’re iconic of the tropics and few things make me as happy as seeing one flying through the treetops. The keel-billed toucan (otherwise known as the rainbow-billed toucan) is among the most spectacular of these spectacular birds. Like yesterday’s sloth, this one was photographed in Soberania National Park in Panama. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 1600, f/4 at 1/800th of a second.

A three-toed sloth doing what three-toed sloths do — hanging in a tree taking his time. This one was photographed in Soberania National Park in Panama. Panama is a great place for sightings of both three and two toed sloths. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/160th of a second.

A broad-billed motmot enjoying a mid-day snack in El Valle, Panama. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 400, f/4 at 1/160th of a second.

Panama is a great location for nocturnal shooting — especially the bounty of tree frogs that always seem to be about. This is an hourglass tree frog photographed in the highlands of El Valle. Nikon D800 with Nikkor 105mm macro lens, ISO 200, f/25 at 1/60th of as second, two Nikon SB-900 flash units.

Some of you might remember when I posted an image of one of these frogs in the past and referred to it as the “chicken eating frog.” It’s true. They have been known to eat chickens. They also eat bats, among other unfortunate creatures. They are very large and bulky. Over seven inches in length. And they are also toxic. They live in tropical regions of Central and South America and are strictly nocturnal. I photographed this one in the El Valle region of Panama. Nikon D810 with Nikkor 200-400mm lens (at 310mm) ISO 800, f/6.3 at 1/160th of a second, two Nikon SB-900 flash units.

Male three-toed sloths are easily distinguishable from females because they have an orange patch with a black vertical stripe down the middle of their backs. I photographed this sleepy guy one morning in El Valle, Panama.

Just a canal zone tree frog sitting on a leaf in El Valle, Panama. The internet doesn’t provide much info on these guys, so let’s just leave it at that.
