Stony Point Road, Petaluma, CA
January 20, 2012
Rainy, after dark
I spent the evening helping graduate student Tracy Bain with her California Tiger Salamander field study. We were recording data on salamanders as they approached Stony Point, preparing to cross the road to access the vernal pool where they breed. Stony Point Road (near Meecham) is terrifying, especially in the rain, because the cars so by so fast! As you might imagine, this is often disastrous for the little tiger salamanders trying to cross the road in the dark, in the rain. In order to reduce road mortality in this critically endangered species, a series of three tunnels were installed under the road, along with driftnet fencing, in the hope that the salamanders would use them to cross safely under the road. On this night, I was assisting with data collection to see if the salamanders were, in fact, using the tunnels.

The final Field Herpetology trip of the semester took us to Galbreath Wildlands Preserve in Mendocino County, primarily to look for Rough-skinned Newt.

Today, Field Herpetology returned for a second visit to Boggs Lake, to excavate another Western Pond Turtle nest that we had located during our field season back in June, in order to raise the baby turtles long enough to determine their sex, as part of an ongoing research study. In addition to the turtles, we saw a good variety of other wildlife, as well.

Nick, Nicole and I took the Field Herpetology class on a field trip to Boggs Lake for a tour of our field site and an overview of the research that we’ve been doing on the nesting behavior and sex determination of Western Pond Turtles.

September 23, 2011
After dropping my kiddo off with their dad for the weekend, I went on a solo birding adventure to Shollenberger Park. Loads of great birds (as usual), including American White Pelican, Northern Shoveler, Greater Yellowlegs and Pacific Golden Plover – a new bird for me!

We visited two sites for California Giant Salamander: Purisima Creek in Half Moon Bay, and Sierra Azul, near San Jose. We walked the creek at both locations, searching for salamanders.

Phalaropus tricolor
August 1, 2011: Shollenberger Park, Sonoma County, CA
While walking around the retention ponds, I spotted a pair of these delicate, pretty birds swimming and wading in the shallow water very near the shore. This is the first time I’d seen this species, and since they were in fall plumage, the ID was a bit difficult at first. The eye stripe, neck coloration, and white rump helped give me the ID.

On my birthday, I spent the day birding with Eclipse and Andrea. We started at Shollenberger, then had lunch at Lily Kai, and then visited Willow Creek in the Laguna de Santa Rosa.

This is a collection of observations made while doing field work at Boggs Lake in Lake County, California. We were focusing on the nesting behavior of Western Pond Turtles, but we also saw loads of other great wildlife at this Nature Conservancy site. Note: some of these dates might not be exact, but all wildlife was seen during the month of June.

June, 2011
This campground, just a few miles away from our Boggs Lake field site, is where we camped throughout the field season. The facilities were nice – bathrooms with showers, a recreation room with wifi – and we had a permanent campground where we all set up our tents together. I usually spent about a week at a time up there, trading off as the field lead with my lab partner, Nicole. Since the turtles we were studying really only became active mid-afternoon, we spent quite a lot of time at the campground.

May 20, 2011
14:05, 70° F, sunny and clear, but windy
As part of our field trip to the Golden Gate Raptor Observatory at the Marin Headlands, we went to the top of Hawk Hill. It is not a migration time, so we didn’t see a large number of birds, but there were still a few feathery friends in the area, including California Brown Pelican diving in San Francisco Bay, Brewer’s Blackbird near Fort Cronkhite, and White-throated Swift near the top of Hawk Hill.

Salvadora hexalepis mojavensis
May 14, 2011: Zzyzx Desert Studies Center, San Bernardino County, CA
An exciting catch! This snake was spotted on Zzyzx Road from one of the vans, so we stopped to try and get a better look. It went into a medium-sized Sweetbush, but after several minutes, the snake came back into view: an adult male, with an orange belly.
Mojave Desert: Bajada and Microtower Road
May 14, 2011
With another full day ahead, I started out with a short solo walk on the property before the rest of the day’s activities. I saw a good number of birds, plus a Desert Cottontail. New birds included a Green Heron flying along the salt flat, a Spotted Sandpiper tail bobbing on the fountain in Lake Tuendae, a Belted Kingfisher flying and calling at the lake, and a pair of Red-tailed Hawks on the rocks near the road between Zzyzx and Baker – the first hawks I saw on this trip.
