Costa Rica 2011 The Art of Biodiversity – Part 3

Arenal Observatory Lodge

Arenal is the country’s most active volcano, with continuous emissions of lava and incandescent pyroclastic flows since the beginning of the present active cycle in 1968. In 2010 when I visited this location, the eruptions could be heard day and night roaring, coughing and spitting, but due to the low cloud cover, not seen. I did get a view of the pyroclastic flows through a break in the clouds for about 30 seconds one evening. The weather did cooperate this year with clear skies one evening and clear skies one morning during sunrise. Unfortunately, the volcano stopped erupting to a great extent three months prior to our visit. It was quiet. You could still see steam coming from several vents in two locations near the summit, but no fireworks. The lodge grounds offer many gardens, and there was an extensive garden right outside our room where we could observe hummingbirds feeding at the flowers.

We spent one day at a nearby facility that houses a wonderful collection of frogs, toads, snakes, and lizards. The staff set up several stages with natural vegetation, moss covered rocks and stumps; the vegetation on the nearby hills provided out of focus backgrounds, and we could photograph with natural light or with fill flash as we chose. It was a great opportunity to photograph species which would be difficult, if not dangerous, to photograph in the wild. The facility also had a butterfly enclosure which I visited while waiting for the set ups to be ready. Once the stages were completed, several species were brought out and placed in the setup. An experienced caretaker stayed with the animal at each set up, repositioning the subject when it moved into a position that was not photographic. The caretaker would replace the animal when it appeared to be too active, or when photographic interest in that subject diminished. At the end of the day, one caretaker asked my wife Chris if she wanted to hold the Rainbow Python, which she did. She was surprised that it was very soft to the touch.

We also spent a morning at the Danaus Ecocenter. There was a limited number of birds in the area due to the time of year, but quality is often better than quantity. We had quite a long time with several Collared Aracaris feeding on fruit very close to the path. And one of the guides showed us the location of a baby three-toed sloth since it was not on one of the main paths, but on a service road.

All in all, Arenal Observatory Lodge is one of those locations in Costa Rica which could easily support a week’s worth of photographic subjects, if you know where to look. There are trails up through the forest to the lava fields and a large lake that we didn’t explore on this trip. However, unless you were on a Foto Verde guided trip, you wouldn’t have the opportunity to photograph the variety of reptiles that I did on this trip.

Selva Verde Lodge

We spent three days at this tropical rainforest lodge located on the banks of the Sarapiqui River. The attraction here is the abundance of green and black poison dart frogs and red poison dart frogs as well as masked and red-eyed tree frogs. One back lit basilisk lizard was a challenge to photograph as we tried to move through the undergrowth off the path and not chase the lizard off. There were also lizards climbing a tree next to the dining room, and we even saw a baby fer-de-lance on the side of the path. It couldn’t have been more than three inches in diameter coiled less than a foot from the path. The lodge naturalist moved the snake into the forest for everyone’s (and the snake’s) safety. When Greg was selecting some vegetation for nighttime photography of a red-eyed tree frog, he explained that we had to carefully look under the low vegetation to make certain no fer-de-lance were there. We could hear numerous birds throughout the forest, but they were elusive with the exception of a mot-mot, a chestnut billed toucan, and an ochre bellied flycatcher on the nest. We also had some time with howler monkeys which were very close and almost eye-level from the balcony of the lodge’s classroom. The naturalist believes they come to see their reflection in the floor to ceiling windows.

One morning we traveled to a nearby farm owned by a local family that has preserved some of its property as forest. Great Green Macaws and Scarlet Macaws live in the forest and stay close to the farm to roost and feed. He also had a large enclosure that injured birds, which locals had found were rehabilitated and allowed to go free. There is an opening in the cage where birds can come and go as they please. The owner also rescued two jaguars from being hunted and killed by local villagers for killing cattle. The farmer got the villagers to agree to let him capture the animals rather than just kill them. He built an enclosure to house the jaguars and takes good care of them; they look healthier than some zoo animals I’ve seen.

Costa Rica 2011 The Art of Biodiversity Part I

Chris and I traveled recently to Costa Rica with my friend and tour leader, Greg Basco, cofounder of Foto Verde Tours, a provider of tours designed for photographers. Last year I traveled to Costa Rica with Joe and Maryann McDonald primarily to photograph hummingbirds, and met Greg who organized and co-led the trip. This year I signed up early for the Art of Biodiversity tour which offered a wider variety of photographic subjects at the start of the rainy season. Chris decided to join me at a later date, which worked out well as there were only two other participants for a total of four plus Greg and Jose Lopez, our driver and also a very good photographer.

My blog entries for this trip will be divided by location, starting with the Bougainvillea Hotel in Heredia, near San Jose, the capital of Costa Rica. We also traveled to Selve Verde Lodge, the Arenal Observatory Lodge, and the Bosque de Paz Ecolodge as well as side trips from those locations.

The Bougainvillea Hotel This was my third trip to Costa Rica and each time I stayed at the Bougainvillea to start and end each trip. Tour providers choose this hotel in a residential area for its 10+ acres of gardens that include over 50 species of bromeliads, native trees, orchids and frog ponds. Each visit offered different plants in blossom. And while my two visits in March had quite a few birds in the garden, in June the migratory birds were gone, and the local birds were raising chicks and mostly staying hidden. There were more plants in blossom, but fewer orchids. In any case, I wasn’t disappointed with the opportunities to use my macro lens.

Yellowstone National Park in Winter
Part 2

After attending the Natural Exposures Yellowstone in Winter Photo Tour described in Part 1, I picked up a rental car in Bozeman and continued my winter adventure based in Gardiner, MT. Gardiner is only a few miles from the north entrance to the park and Mammoth Hot Springs. Highway 212 passes through the northern section of the park to Cooke City just outside the northeast park boundary. This road is maintained year round and is the only means to reach Cooke City during the winter.

Yellowstone National Park in Winter — Part 1

Yellowstone National Park in Winter — Part 1

I’ve always wanted to visit Yellowstone in winter to photograph the scenery and wildlife. After considerable internet searching, this year I signed on for a February trip with National Geographic contributing photographer Daniel J. Cox (Natural Exposures). The trip schedule included four day-long excursions by snow coach into the park from West Yellowstone and a day on either end to travel from/to Bozeman. Since I was going to travel to Montana, I added on three days of photographing the park from north entrance at Mammoth Hot Springs, the only area of the park that clears the roads for automobile travel during the winter. More about my independent travels in Part 2.

Part 1 is long and includes both my trip report and a review of the Natural Exposures Yellowstone in Winter Photo Tour for those considering this trip or this tour company. [Read more…]

Audubon Magazine Birds In Focus Winner

GRAND PRIZE WINNER

My image of a Green-breasted Mango was selected as Grand Prize Winner of the Audubon Magazine Birds In Focus photography contest. It was selected from the 8,000 entries in this year’s competition. The image is one of the thousands of images I captured during my trip to Costa Rica in March 2010. You can find the announcement of the winners at Audubon Magazine.

Another of my entries was selected as one of the Top 100 images of the contest and can be seen here. Rather than tell you which one is mine, I’ll leave it to you to explore all of these wonderful images. After you see these images, you’ll understand how honored I am that my image was selected from among those images.

Fall Color in Rhode Island

The leaves are changing and there’s no predicting where it will be good color, or when. For the first time ever I ventured into western RI to find locatons for fall color photogrpahy. All of these images used High Dynamic Range techniques to capture the hightlight and shadow detail in the high contrast situations. While I definitely needed this technique for cases where the scene was in a dark location (graveyard, stream) and it was backlit, I tried it on reflected light scenes to see if it made a difference and to get some experience in processing those types of images. The first two images were taken 8 October at Carbuncle Pond, and the others were taken on or near the Scituate Resevoir on 13 October.

Jack-o-Lantern Spectacular

Thesea photos were taked at the Jack-o-Lantern Spectacular at Roger Williams Zoo. The featured pumpkins are painted with black ink on teh outside and carved on the inside to allow differing amounts of light to shine through the pumpkin. Hundreds of traditionally carved pumpkins also line the walkway and fill in the spaces around pumpkins decoreated following the theme for the year.

Backyard Hummingbirds

After my trip to Costa Rica I planned to again try my hand at hummingbird photography in my yard. In past years, many hummingbirds, all Rubythroated, would visit my feeders. Usually one would arrive even before the feeder was up, hovering in front of the window location where it is usually mounted. Clearly that bird had been here before. This year was different. This year, we only had one male most of the time, with a second one showing up occasionally, and we had only three females. The male dominated the feeder until I set up a second one out of sight of the other. Now the male guards one feeder, and the three females seem to spend more time chasing each other around the other feeder than eating.

After several weeks of photographing, I haven’t been able to catch the male’s gorget fully lit up. Most captures that are a side view of the male results in dark, almost black gorget feathers. There always seems to be a dark patch of red gorget that never lights up. It’s very difficult to catch the throat lit up, and only seems to happen if the bird is facing the camera, but even then, there’s a patch in the center that doesn’t fully light up. I’ll have to experiment more with light placement to see if I can get better results. Up to now the two front lights have been to either side of the flower. Perhaps I need to place one below and directly in front of the bird. In the past, I’ve used a camera mounted flash with a BetterBeamer to trigger the other flashes. That may provide enough direct light, if lack of direct front light is the cause of the dark feathers.

I’ve been using the Canon 7D with the 500mm f4 Is lens since the birds were very wary of me being nearby. Now they are more comfortable with me there and I’ve been using the 100-400 zoom lens. . I can’t rotate my camera for vertical compositions because the built in flash controller of the 7D will not see all the remote flashes if I do so. So I’ve been taking images with less zoom with the intent of cropping for vertical presentation. The portrait images were taken this way.

There are not many more days to photograph hummingbirds; the males will leave soon and the females a couple of weeks later.

Costa Rica Photography Trip IV

One of the challenges I set myself was to capture hummingbirds landing. It’s not a matter of just setting the camera to the highest frame rate and hope for the best, but an anticipation that the landing was going to occur. With the lens focused on the flower, and framed wide enough to capture the bird as it came in, I’d take my eye away from the viewfinder and look at the larger scene to spot a hummer coming in for a landing.

Since the birds are attracted to the photographic setup using a feeder, the images are predominantly side views of the hummingbird coming in to the feeding tube. I tried to be aware of the flight of the hummer and attempt to get some images with the birds in different attitudes.

Another technique that Greg Basco suggested is to use a longer flash duration to get a little blur in the fastest moving parts of the hummingbird, the tips of the wings. In one setup we set the flashes to 1/8 power which froze the image of most of the bird. These two images were taken at f25 and using multiple flashes as the main light. In another setup where full sunlight was lighting the bird and background, the camera was set for a longer exposure to let the moving parts blur quite a bit, and the light from the flashes freezing a portion of the bird that did not move much. This had a lower success rate. The last three images were take at 1/25 second and f8. You can see the amount of wing motion in that short amount of time.
