I shot this anhinga (Anhinga anhinga) from a boat in the canals near
Tortuguero National Park. He was sunning himself to dry his wings.
Anhingas are closely related to cormorants, and behave in much the same
way.
This lizard (Basiliscus plumifrons) was also shot from a boat on the Tortuguero canals. You can tell
it's a female because it does not have a crest on its head (compare with
the male, below).
This is the male Basiliscus plumifrons, with a prominent crest. These lizards are also known as "Jesus Christ lizards" because they can literally walk on water. They run very rapidly across the surface, and their feet are big and are shaped exactly right for this purpose. They're not tiny lizards, either -- I've seen them 70 or 80 cm long.
They run so fast across the surface that it's almost a blur. About the
only thing you're sure of is that the lizard disappeared from one side
and reappeared on the other, and the surface of the water is disturbed
where its footsteps were.
We saw this frog (Agalychnis callidyras) a "night hike" in Tortuguero. On a night hike, you go wandering around in the jungle at night with a flashlight, and you see a completely different world from what you see in the daytime.
This is not one of the "poison dart frogs", but we did see some of
those. I like the coloration -- the eyes, feet, and blue striping on
the undersides of the legs is spectacular.
This was another "night hike" discovery in Tortuguero. We watched the adult form pull out of the shell of its previous self. The entire process took about an hour as it slowly pulled out each leg.
The most amazing thing was the extraction of the antennae -- they're far longer than the rest of the body, and were the last to come out. To get them out, the katydid stretched its head forward as far as it could, and pulled out a tiny loop. Then it repeatedly pulled its head back, grabbed the antennae in its jaws and pulled its head forward again. Each cycle pulled out another half millimeter or so.
When everything was finally out of the old shell, the new wings had to
be pumped up, and that took so long we finally went to bed without
seeing the job completed. But in the morning when we returned to the
site, the katydid was gone, and so was the old shell. Many insects eat
their old shells so as to waste nothing.
This lizard, known as the Helmeted Basilisk (Corytophanes cristatus) was sitting in a tree just outside our window when we were staying at Wilson Botanical Garden, 6 km south of the town of San Vito, near the Panamanian border.
It stayed there for 3 days, through sun and rain, and never moved more than a couple of inches. There was some disagreement among experts as to the name of this lizard, but now I am quite sure that the identification in the previous paragraph is correct.
These leafcutter ants were carrying their leaves through Wilson Garden. They often can be found in long trails, sometimes hundreds of meters long. They cut chunks out of leaves and then carry the leaves back to their nests. They're "normal" sized ants -- perhaps 4 mm long.
What's interesting is that they don't eat the leaves -- they chew them
up and use them to grow a fungus, and then they eat the fungus. The
ants never eat anything but the fungus, and the fungus is found nowhere
except in the nests of leafcutter ants. It's clear that the partnership
has been evolving for quite some time.
This is a wild monkey (but just barely) in Manuel Antonio National Park. There are dozens of them, and since the park is one of the most popular weekend destinations of Costa Ricans, they're used to lots of people.
This guy had just stolen some mango from picnicers, and you can still see the juice smeared all over his face and chest.
They are far more dangerous than they appear. Luckily, I was
photographing them with a 300 mm lens, but my friend had a little
point-and-shoot camera, and had to get quite near to get decent shots.
His subject was completely tame, but he didn't notice that his head was
directly underneath another monkey who proceeded to defecate all over
him. It took quite a bit of time fully clothed in the surf to get rid
of most of the smell!
When we had an extra day in San Jose, we took a trip to the neighboring town of Cartago, partly to see the Lankester Botanical Gardens, and partly to see if we could figure out how the bus system worked.
The gardens are amazing! There are hundreds of species of orchid, and
plenty of other interesting plants as well. I don't know the species
here, but I loved the geometrical form.
We ran into this Froot Loops bird (Ramphastos sulfuratus) in a restaurant near Carrera Park. He lived in
a tree just outside the open-air restaurant, and came in to finish off
any fruit left behind on the plates of the customers. When this photo
was taken, he had already chowed-down quite a load of papaya and was
pretty docile. There are two species of large toucans in Costa Rica;
the other is the Chestnut-mandibled.
My wife is a neurologist, and one of the more bizarre and interesting neurological diseases is called "kuru" -- it's found in New Guinea, and is passed when people eat the uncooked brains of their dead ancestors who died of the disease. It's related to "mad cow disease", and is probably caused by a prion -- a protein-based infectious agent.
So what does that have to do with the ringed kingfisher
(Megaceryle torquata)? Well, when we were trying to decide where
to go, we found a nature reserve called "Curú", and it was
obvious to my wife that we had to visit it. We saw lots of great
animals there -- wood storks, roseate spoonbills, ctenosaurs, et
cetera, but the only decent photo I got there was of this
kingfisher.
It's hard to capture the beautiful irridescence of the blue feathers on the head of this bird (Momotus momota), but it's not hard at all to show the classic motmot tail. Every bird is missing some of the barbs on the tail feathers leaving a tennis-racquet-like feather. Different species of motmot are missing different amounts of feather.
Nobody knows whether the bird pulls off the barbs itself, or whether the
barbs in those areas are naturally worn off because the feathers rub
together in a funny way.
I found this bird (Chlorophanes spiza) in a bottle-brush plant (Hawaiian) in the Wilson
Garden. And to answer your question: No. I did not get those colors
by running the image through Photoshop. The bird had those colors
itself.
