A Flock of Skimmers

Rynchops niger

Stearns Wharf

Santa Barbara, California

April 24th, 2010

Last weekend my wife was overnighting in Santa Barbara, so I decided to surprise her and I drove out to take her to dinner. I left a few hours early so I could stop along Stearns Wharf and photograph the human activity along the coast. I wasn't expecting to photograph the wildlife, but when I saw this flock of Black Skimmers I couldn't resist. 

The Black Skimmer (Rynchops niger), is a unique bird among American birds, making its identification unmistakable. What sets it apart is it's red and black bill that is noticeably uneven (the lower mandible is approximately 2-3 cm longer than the upper portion), which it uses to skim the water looking to catch small fish. One interesting fact, is that skimmers are born with their upper and lower mandibles even in length, but by the time they fledge, the lower mandible has grown longer than the upper half. 

The Black Skimmer's traditional North American range has been the Gulf Coast and the Eastern Seaboard, but in the early 1960's, a few were spotted along the Southern California coast. In 1968, a few were spotted nesting at the Salton Sea. Since then, their range, in California, has expanded to include the Coast from San Diego to Monterey County and San Francisco. Today, it is estimated that there are over 1,200 nesting pairs at the Salton Sea and along the coast.

Out on a Limb

Rhacodactylus ciliatus

RNA (A.K.A. Ribo)

Glendale, California

August 6th, 2007

I took this photograph of one of my male crested geckos a few years back. I own several crested geckos, as well as a pair of viper geckos, several bearded dragons, and an anerythristic corn snake. Of my collection of reptiles, I think the crested gecko has one of the most interesting natural histories. 

The crested gecko, Rhacodactylus ciliatus, is endemic to southern New Caledonia (Grand Terre and the Isle of Pines). It was first described by Alphone Guichenot, a French zoologist, in 1866. The gecko was thought to have been extinct until it was rediscovered in 1994. A few individuals were taken back to the United States and Europe were the gecko was found to be a prolific breeder, and easy to maintain. Today they are one of the most popular geckos to keep. 

Unfortunately, the in the wild, the crested gecko has not been so lucky. This species is threatened by human encroachment on its habitat, and by the introduced little fire ant. The little fire ant (Wassmannia auropunctata) was introduced to New Caledonia sometime between 1955 and 1972. It was most likely brought in with ornamental or agricultural plants. The ant competes with the gecko for food (insects and other small arthropods), and preying on the gecko itself. 

A Towhee Poses for a Picture

Pipilo crissalis 

Sepulveda Basin Wildlife Reserve

Los Angeles County, California

March 28th, 2010

This little California Towhee (Pipilo crissalis) posed for a few pictures on a recent birding trip to the Selpulveda Basin Wildlife Reserve. This trip will be memorable because it was the first trip I took with my wife. She was great for her first time out, she often spotted unique birds before I did, and she makes a great companion. Hopefully, she will join me on future outings as I had a great time with her. 

The California Towhee is a common bird of the chaparral and scrublands of California and Southern Oregon. They are uniformly brown, with a reddish brown eye-ring and under-tail coverts. They essentially look like a big brown sparrow. They tend to live in the dense shrubs along coastal slopes and foothills, but they are also resident visitors of backyards and city parks. One interesting bit of information on this towhee is that they often make their nests in poison oak (Toxicodendron diversilobum) and feed on the plants berries. 

Basking in the Sun

Sceloporus occidentalis

Sepulveda Basin Wildlife Reserve

Los Angeles County, California

March 20th, 2010

I found this little western fence lizard (Sceloporus occidentalis) basking in the sun during a recent outing to the Sepulveda Basin Wildlife Reserve. He was nice enough to sit and pose for a few pictures before scrambling out of sight into the undergrowth. These are one of my favorite native reptiles, and I love to watch them and capture them on film.

Not only are the western fence lizards beautiful to look at and fun to watch, they are beneficial to the ecosystem as well. In areas with a population of western fence lizards, the incidence of Lyme Disease is significantly lower than in areas without these little reptiles. Apparently the lizard's blood contains a protein which kills the spirochete bacterium Borrelia burgdorferi that causes Lyme Disease. 

The Sepulveda Basin Wildlife Reserve is located just North of the 101 Freeway and West of the 405 Freeway. The  225 acre park is home to a wide variety of wildlife including California ground squirrels, cottontails, coyotes, California red-legged frogs, Pacific treefrogs, western fence lizards, side-blotched lizards, and over 200 visiting (migrating) and resident species of birds. There is a path that winds through the reserve with several viewing areas that overlook the lake. When visiting please stay on the path and leave your pets at home. The native scrub land is beautiful, but can also be fragile if not taken care of. 

A View from the Top

A Unique View of the Rainforest

La Selva Biological Field Station, Costa Rica

July 14th, 2009

This photograph was taken from atop a research tower at the OTS La Selva Field Station. The total height of the tower is just over 40 meters. On a clear day at the top, you can see the chain of volcanoes that run like a spine down the center of the country to the west, and the Caribbean to the east.  It was partly cloudy on the day I climbed the tower, so most of the view was obstructed, but what I did see was amazing. After climbing to the top of this tower, I climbed part way down and crossed a bridge to the second tower. From here, I made my way down to the ground. I will say the whole experience was a little tense, but well worth it. I would not have wanted to miss out on this experience; one that few visitors get to have. 

The towers themselves are part of a long term project to study the Carbon Cycle and climate change. The towers I climbed are only two of several scattered throughout the forest. Our guide was telling my group that there are plans to add additional towers to this site and monitoring equipment that will make it possible to collect data remotely. 

A Lonely Trail at Deukmejian Wilderness Park

La Mesnager Loop Trail

Deukmejian Wilderness Park, California

May 31st, 2009

Deukmejian Wilderness Park is one of my favorite places to hike in Glendale, California. I discovered this park about four years ago when I purchased the book Afoot and Afield in Los Angeles County by Jerry Schad. The La Mesnager Loop Trail is a 1.4 mile (2.2 km) hike with only a 420 foot change in elevation. It is easy to maneuver in a sturdy pair of cross-trainers but I prefer a pair of light boots. As you reach the top of the mountain make sure to take a quick 50 yard side trip up the La Mesnager Lookout Trail. On a clear day from the lookout you can see Catalina Island. Once back on the main trail, you might want to veer off once again and take the steep (1195 ft change in elevation) Rim of the Valley Trail, this trail will take you up the mountain to the Haines Canyon Road. I usually double-back down the trail and return to the La Mesnager Loop Trail. Another option is to stay on the La Mesnager Loop Trail and take the short jaunt the end of Dunsmore Canyon, before finishing your hike.

The photograph above was taken in the Spring of 2009 just three months before the devastating Station Fire. Unfortunately Deukmejian Wilderness Park was burned as part of the effort to save the community surrounding the 704 acre park. The park itself is closed for the time being, and hopefully it will re-open again in the near future. If you would like to see images of the park after the controlled burn, including one taken in almost the exact location of my photograph you can click here: City of Glendale: Community Services and Parks.

Night Walk Along the Camino Cantarana

Scinax boulengeri

La Selva Biological Field Station, Costa Rica

July 15th, 2009

This Boulenger's Snouted Treefrog was photographed along the boardwalk of the Camino Cantarana at the OTS La Selva field station. The Cantarana (frog song) trail was one of my favorite night spots during my trip to Costa Rica. The trailhead was only a few meters from the academic building and we would often take a quick trip down to the boardwalk before heading on the one kilometer hike back to the Cabinas. At night the Cantarana trail is alive with the sound of frogs calling and snakes hunting, every night was an adventure with new organisms to observe and photograph.
