My Favorite Places

Bolsa Chica Ecological Reserve
Huntington Beach, California
February 21st, 2011

One of my favorite places to go birdwatching in Southern California is Bolsa Chica Ecological Reserve in Huntington Beach. It consists of over 1,200 acres of coastal wetlands and chaparral scrub and over a mile of trail that loops through the reserve. A walk through the reserve will allow you to observe native flora and fauna of Southern California. Throughout the year over 300 species birds migrate through or nest in the wetlands including the endangered California Least Tern. The reserve is also habitat for several mammal and reptile species including cottontail rabbits, Beechey ground squirrels, Pacific rattlesnakes, and Western fence lizards. If you find yourself in or near Huntington Beach, California I suggest you visit Bolsa Chica.

Sepulveda Basin Wildlife Reserve
Los Angeles County, California
November 21st, 2010

Another one of my favorite places to go birdwatching is Sepulveda Basin Wildlife Reserve in Van Nuys. The wildlife reserve consists of a 225 acres of riparian habitat,  chaparral scrub and an 11 acre lake. Late fall to early spring is the best time to visit the reserve for the purposes of birdwatching. According to the Sepulveda Basin Wildlife Reserves website over 200 species of birds make migrate through the reserve yearly, many are actually found here year round. I personally have counted over 100 species during my many trips to the reserve. Besides birds you may also see several species of mammals and reptiles including  Beechey ground squirrels, Western fence lizards, and cottontail rabbits. Because of the proximity to my house this reserve is one of my most frequented locations. If you are in the area it is a great place to visit.

Del Rey Lagoon Park
Playa Del Rey, California
February 2011

Another place I love to visit, like Bolsa Chica is also near the coast. Playa Del Rey is a small beach community south of Marina Del Rey. At it's center is Del Rey Lagoon Park with a saltwater lagoon that ebbs and flows with the tide. I like to stroll around the lagoon looking for waterfowl and shorebirds. I then walk along the jetty watching the pelicans and other sea going birds, as well as the many fishermen fishing among the rocks. Occasionally I will walk along the beach path and check out the gulls and, in the right season, the terns who hang out on the sand. During the fall and spring migrations over 200 species of birds have been observed including several endangered and threatened species like the California least tern and the snowy plover. 

Just east of Del Rey Lagoon Park is the Ballona Wetlands which consists of both brackish and freshwater marshes as well as a riparian area. The sensitive estuarine and brackish areas are only open for visitation by appointment or during schedules community events. See the Friends of Ballona website for more details regarding community events or visits. The Freshwater marsh and riparian zone are open to the public. You can enter this portion of the wetlands at the corner of Jefferson and Lincoln east of Playa Del Rey. Since Playa Del Rey and the Ballona Freshwater marsh are so close to LAX, I will often visit here before or after picking up friends or family from the airport.

A Curious Squirrel at the Park

Sciurus niger
Del Rey Lagoon Park
Playa Del Rey, California
February 19th, 2011

After a successful day of counting birds for the Great Backyard Bird Count, we were sitting in the park when this curious fox squirrel (Sciurus niger) came toward us. It was very tame and I suspect was used to getting snacks from passersby. I was able to get in quite close to the squirrel and take several photos of  before it scurried up a nearby tree.

The fox squirrel (S. niger) is actually not native to Southern California. Historically the squirrel's range was the Eastern United States, where it inhabited the interface of the deciduous forests and the prairies. Today it can be found as a common inhabitant of urban and suburban areas throughout the Eastern United States and has been introduced to California, Idaho, Montana, Oregon and Washington. 

According to Julie L. King (2004), the fox squirrel was introduced to Los Angeles around 1904. The story goes that residents of the Sawtelle Veterans' Home brought several of these squirrels from the Mississippi Valley to their Veterans' Home. These squirrels subsequently escaped captivity or were purposely set free. Over the last 100 years, their population grown and their range has expanded east to San Dimas, north into the San Fernando and Santa Clarita Valley, west toward Oxnard, and South as far as Newport Beach. Scientists are concerned that this expansion may be displacing the native western gray squirrel (Sciurus griseus). 

below is a bonus image of this curious little squirrel.

The Charismatic "Mesofauna" of Bolsa Chica

Spermophilus beecheyi
Bolsa Chica Ecological Reserve
Huntington Beach, California
May 29th, 2010

On my way back to the car from my birding trip to Bolsa Chica Ecological Reserve, I came across this very charismatic Beechey Ground Squirrel. I couldn't resist stopping and taking a few photographs. The squirrel was so photogenic I had to insert another memory card to finish the shoot. I couldn't believe how tame this squirrel was, normally they are quite shy and run into the scrub as soon they see you.

There are 23 species of ground squirrels and 119 recognized subspecies in the United States. Throughout California there are at least 5 native species, with one source listing as many as 18 (including subspecies). The Beechey Ground Squirrel (or California Ground Squirrel) is the most common species observed in Los Angeles and Orange Counties. 

Since this squirrel was so charismatic I have included a few bonus images below.



Nesting Terns at Bolsa Chica Ecological Reserve


Sterna antillarum browni
Bolsa Chica Ecological Reserve
Huntington Beach, California
May 29th, 2010

This weekend I went birding at one of my favorite Southern California locations, Bolsa Chica Ecological Reserve. The reserve is located just east of PCH and is bordered to the north by Warner Avenue and to the south by Seapoint Avenue. The reserve consists of approximately 1,200 acres of wetlands and several miles of trails. It is an amazing place to bird. Historically over 320 species of birds have been spotted here, with many, including terns, plovers, and herons nesting in the reserve. I have personally observed over 50 species between the months of February and May this year alone. If you would like to learn more about the ecological reserve or plan your own birding trip click here.

The California Least Tern (Sterna antillarum browni) is one of three least tern subspecies that breed in North America. All three of which are listed as endangered under the Federal Endangered Species Act. One of the reasons they are endangered is that they nest along the sandy shoreline and have to compete with humans for territory. As their preferred nesting locations disappear, they have been forced to nest on  flat gravel roofs of building, or in mudflats. Unfortunately these nesting locations are not ideal, a roof can heat up causing tar to seep through the gravel sticking to fledgling birds, and mudflats can make the birds more prone to predation. Additionally, over-crowding of ideal nesting locations can also make the birds more vulnerable to predation. 

Since 1970, when the California Least Tern was listed as an endangered species, conservations efforts have been somewhat successful. The population has grown from 225 nesting pairs to over 6,561 pairs recorded in 2004. Biologists though, are still worried that the distribution of the species is limited and without future management may not be viable. With an increase in public awareness and future conservation efforts maybe these little terns will have a better chance.

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.
