Equinas River Mangrove Tour

New Year's Day 2010, part II

Deeper into the Golfo Dulce...



The further out into the gulf we got, the inkier and "thicker" the water became. The Golfo Dulce is one of the deepest gulfs in the world, more than 1000 feet in parts on the Golfito side. Carlos said that Jacques Cousteau dived here (and never made it near the bottom.) You could just feel the depth as the waves quieted down.







Supposedly our boat driver is the only driver that can navigate a boat of this size down the river at low tide.

The mangroves are home to many animals, one of which was causing quite a commotion below. Everyone, except me, was standing on one side of the boat to see this animal. I - freaking out on the other side of the boat with my 90-something pounds - was trying to keep the boat from tipping over. (Nobody else seemed too concerned, but I don't know how these things work?!)

When I had my turn to look, this is what was directly in the tree above us... 

a boa constrictor!

The boat driver asked if I wanted to get a picture. I said no, that's okay, but he insisted I get a picture, so he was helping me keep my balance as I stood on the edge of the boat, holding up my camera directly under a boa constrictor!


The birds flew in these amazingly choreographed patterns.



Then we made our way out in the open again, heading toward the animal sanctuary on the Golfo Dulce coast at CaƱa Blanca.

Chiropterophily: Bat Pollination

I see you! Geoffroy's tailless bat (Anoura Geoffroyi) - photo by Nathan Muchhala Ever since coming across this word, I can't stop saying it: chiropterophily. Chiropterophily, or pollination of plants by bats, is very common in the tropics. Hundreds of tropical plant species are exclusively or at least partly pollinated by nectar-feeding bats. Many tropical flowers are night-blooming, specializing in attracting bats. Bat-flowers are typically white, cream, or pale green in color, making them easier to see in the dark. They usually have a musky, fermented odor - like that of the bat - or sometimes a fruity odor. They have a large, sturdy, open shape with long, bushy anthers so that the bat's head and chest get coated in pollen when it visits. In return for the bat pollinating the flower, the flower provides the nectar that these high-energy flying mammals need.* Tube-lipped nectar bat (Anoura fistulata) - photo by Nathan Muchhala Nectivorous bats have both good eyesigh

Eyeshine in Nocturnal Animals

Peters' Epauletted Fruit Bat (Epomophorus crypturus), Kruger National Park - photo by Peet van Schalkwyk Have you ever noticed how under certain lighting conditions some animal's eyes seem to glow? Animals that are nocturnal hunters - and a few of them that are not - have something called eyeshine . Eyeshine is the light that we see reflected back from the animal's tapetum lucidum (a membrane behind the animal's retina). Light enters the eye, passes through the retina, strikes the reflective membrane, and is reflected back through the eye toward the light source. This phenomenon makes the most of what little light there is at night for these nocturnal creatures. a moth with pink eyeshine Humans can display the red-eye effect in flash photography, but we do not have a tapetum lucidum , and thus, do not have eyeshine. Eyeshine is best observed by wearing a head lamp or holding a flashlight at eye level against your temple because the light is reflected right back

Bats of Bosque del Cabo

Our first night here we saw bats (not sure of the species) flying around at dusk right outside the back of our bungalow, lots of them! And they would fly very near us! What an experience! bats outside Lapa at dusk * * * Some nighttime views from our bungalow's observation deck... Off to bed... * * * At dawn, you could sit out on the observation deck and observe the bats finding their way back home. What an early morning treat! bats outside Lapa at dawn * * * Bosque del Cabo has (that I currently know of): White-Lined Sac-Winged Bats  ( Saccopteryx bilineata / leptura ) in a cave on the Pacific beach (which I learned after our trip) Spix's Disk-Winged Bats  ( Thyroptera tricolor ) - observed in rolled heliconia leaves Jamaican Fruit-Eating Bats  ( Artibeus jamaicensis ) - observed pollinating the Guapinol or Stinky Toe Tree Tent-Making Bats  ( Uroderma bilobatum )  - note: several bat species roost under leaf tents, including the Caribbean or Honduran White
