Panamá Part 8: Animals of the isthmus

A tree frog dozes on its perch at Panamá's Nispero Zoo and Botanical Garden. Panamá has been described as a "fountain of biodiversity" and a "bridge of life". This tiny Central American country, about the size of Ireland, possesses more species of amphibians, birds, and other animals and insects than the United States and Canada combined. Just as Panamá's key geographical position has affected its trade and economic history, that geography has also impacted its ecology. The narrow isthmus is the land bridge between North and South America, allowing species to move in both directions. In addition, it forms a land barrier between the Atlantic and Pacific Oceans. This alters wind patterns, water currents, and salinity, causing species to evolve in different directions depending on their geographic relationship to the coasts. During our visit to Panamá, Carole and I observed some of this fantastic diversity. I say "some" because, with all we saw, we still encountered only a tiny fraction of what is there. Of that which we did see, I can only display a few of the many different creatures I photographed. I tried to pick a representative sample of the most interesting and regret that space does not allow me to include many more.

Animals along the Rio Chagres

A tourist boat cruises along the shore of Rio Chagres looking for interesting critters. As a photographer, I have learned that it is helpful to maneuver your way into a seat in the front row so you don't have to shoot over the heads and shoulders of your fellow passengers. This is easier said than done if there is a large group, but still worth the attempt. The jungle comes right to the water's edge in most places and the overhanging trees are full of animal life.

A cocodrilo conceals itself while waiting for lunch to happen by. This one is young, probably only 1 m (3.28 ft) long. The little croc was partially concealed under the pier from which we embarked. It would probably not be a good idea to sit on the edge of the pier, cooling your bare toes in the water. Although this croc is not big enough to kill you, it could still give you a nasty bite. At the other end of the scale, the biggest croc every found in Panamá measures 5.5 m (18 ft) and weighs in at 998 kg (2,200 lbs). That privately-owned, 111-year-old reptile is named Cassie (short for Cassius Clay). Cassie would be about as big as the tourist boat seen in photo #2. Best to depart the river--rapidly--if you encounter one that size.

Crocodiles like to hang out in the shallows or sun themselves on the river bank. This one is lying curled so that the tip of its ridged tail is almost even with its snout. Because I took the shot with a telephoto zoom, it is difficult to accurately estimate the croc's length, but I would guess about 3-3.6 m (10-12 ft). There have been three fatal attacks by crocs along the Panamá canal during the last three years. Typically, the crocs go after fishermen along the bank or people wading or swimming close to shore. The attacks are sudden and the croc disappears underwater with its victim within seconds. None of the bodies of the three victims were ever recovered.

A white-headed capuchin monkey moves easily among the branches. Cebus capucinus is found throughout Panamá. The males average 3.7 kg (8.09 lbs) and the females about 7.7 kg (5.9 lbs). Because they are so widespread and plentiful, their conservation status is one of "least concern."

A capuchin approaches a tourist as our boat edges into the trees. The monkeys have learned that they will sometimes get a treat from a guide if they come down to a boat. Attempting to touch or pet them is not a good idea. They are wild animals and can deliver a serious bite if they feel threatened. Notice how the monkey curls its tail around the canopy support to ensure its balance.

A Black-headed spider monkey feeds on leaves and fruit it finds in the forest canopy. Unlike the capuchin, the Black-headed spider monkey (Ateles fusciceps) is considered "critically endangered." 80% of the species have been lost in the last 45 years due to predation and loss of habitat. In captivity, they have been known to live for 24 years.

The sloth's reputation for laziness gained it the nickname "nature's brother-in-law".  Above, a two-toed sloth (there is also a three-toed version) kicks back in the crook of a tree branch. I took numerous shots and, after examining the photos, I discovered that the creature had not moved an inch the whole time. The wild sloths are not as laid-back as those in captivity. The sloths in zoos sleep an average of 15 hours a day, while the wild ones only snooze for 9 1/2.  Wild or free, their metabolism is so slow that they only urinate or defecate once a week. Their toes are shaped in such a way that some have been found dead, still clinging to the tree branch from which they were hanging when they died. Too lazy to let go?

Mesoamerican slider/mud turtle climbs out of the water in a quiet inlet. Trachemys venusta panamensis is the Panamanian species of a turtle that ranges from Mexico to Colombia.

Animals of the Nispero Zoo and Botanical Garden

Clouds and mist cloak the wooded ridges overlooking  the Nispera Zoo and Botanical Garden. Nispera is located in El Valle de Anton, a village in Coclé Province about two hours by bus from Panamá City. The village is located at the bottom of the caldera of an ancient volcano. The ridges surrounding El Valle rise 1000 m (3280 ft) above the valley floor, forming the caldera's lip The altitude gives the area a cool, moist climate, very welcome after the warm, humid lowlands. The town and surrounding area are popular tourist attractions. Admission to the Nispera Zoo and Botanical Garden is $3.00. For a Google map showing the location of El Valle de Anton, click here.


A large green Climbing Toad posed on a stump. Incilius coniferus can be found from Nicaragua to Ecuador in lowlands and mountain forests. The toad breeds in ponds, rivers, and streams. The population status is "lesser concern" with some threats coming from habitat loss and pollution.  This guy was about the size of the hardball used in a baseball game.

This Smokey jungle frog blends in well with his habitat. The habitat of the Leptodactylus savagei stretches from the lowland jungles of Honduras to the mountains of Colombia. The population status is also "lesser concern". It faces the same threats as the Climbing Toad. The Smokey Jungle Frog is a bit bigger than the Climbing Toad. This one looked about the size of a softball.

In contrast to the previous two amphibians, the Green and Black Poison Dart Frogs are tiny. The bigger frog above was about the size of a glass marble. In spite of their size, these little guys are dangerous, as you might guess from their name. The Dendrobates auratus can be found from Central America to northwestern South America and its conservation status is "least concern." As to its name, the frog exudes a poison that is strong enough to stop a human heart. However, it only releases the poison if it feels threatened. Some people even keep these guys as pets. Talk about living dangerously! On the other hand, you could also be the proud owner of Cassie.


A White Cockatoo climbs the fence to commune with a visitor. This one appears to be molting. Cockatoos are not native to Panamá and their normal habitat is Indonesia. However, all the animals in Nispera are rescues, so this guy can be considered a naturalized citizen. When excited, they raise their plumes, as you can see above.  Cockatoos can't speak quite as well as parrots, but they nevertheless tend to be quite friendly and chatty. They love cuddling with people. One got separated from its owner and sat in a tree plaintively calling "Daddy! Daddy1". A concerned woman came looking for the small child she assumed was in distress and was dumbfounded when she realized it was a White Cockatoo.

A large green parrot was taking a snooze but woke up when I approached. There are many types of parrots in Panamá, but I couldn't seem to locate any that look like this one. There was no identification on the cage. If anyone can help on this, please let me know in the Comments section below.

A Silver Pheasant struts elegantly around his cage. As my father used to say, this one is wearing his "Sunday Go-to-Meetin' clothes." This Silver Pheasant (Lophura nycthemera) is another rescued resident of Nispera. His normal habitat is Southeast Asia and eastern and southern China.

A Toucan displays his magnificent multi-colored beak. Toucans like to hang out in the tops of forest trees. They range from Honduras to Western Ecuador. Their various populations in Panamá have declined drastically because of deforestation and human predation.

A pair of stately ostriches are also among the rescues. The one in the foreground was quite curious about my camera. He walked very close to me and attempted to look right in the lens. Unfortunately, this ended up blurring the photo, so I couldn't use it. He was quite entertaining. Ostriches are flightless and are native to Africa. They are often found in desert areas quite different from the cool cloudy highlands of Panamá.


Baird's Tapir is one of four species of the mammal found in Latin America. It was named for American naturalist Spencer Fullerton Bairds who observed the animals during a trip to Mexico in 1843. With a length of 2 m (6.6 ft) and a body that can weigh up to 440 kg (880 lbs), the tapir is the largest land mammal in Central America. It is a solitary animal that likes to forage at night on leaves and fruit and soak in cool ponds with just its snout above water. While it is herbivorous, it can be dangerous and has been known to charge and gore humans when threatened.

The Lowland Paca (Cuniculus paca) is a large tropical rodent. It ranges from Mexico to Argentina and is about the size of a small dog. A large paca can weigh as much as 12 kg (26 lbs). The paca has been given many names by the people in the wide area it inhabits. In Panamá it is called conejo pintado (painted rabbit). When threatened, a paca will swim out into a river or climb a tall tree. In addition, its burrows usually contain more than one exit. Pacas are related to agoutis.

The common agouti has a wide range, from Mexico to South America and the Lesser Antilles. There are several species of agouti under the genus Dasyprocta. In addition to pacas, the agouti are related to guinea pigs. They tend to be smaller than pacas, weighing up to about 6 kg (13.2 lbs). In the wild, they flee humans, but become trusting in captivity. Agouti can run very fast and will keep a pack of dogs occupied for hours.

A pair of jaguars nap in the warm afternoon sun. Jaguars are the largest of the cats that live in Panamá, or the whole Western Hemisphere for that matter. They are exceeded in size only by the African lion and the Asian tiger. They hunt by stealth, not speed, and will ambush unwary prey. Unlike other cats, who strangle their prey with their jaws, jaguars pierce the skull and brain with their fangs.

Kind of makes you want to reach out and tickle him on the whiskers, doesn't it? Jaguars average about 100 kg (220 lbs).  Prehispanic people as early as the Olmecs (1500 BC) viewed jaguars as a link with the underworld because of their preference for hunting in the dark.
