Science in Laguna San Ignacio
Low-impact, environmentally friendly ecotourism and sustainable fishing operations benefit local communities of San Ignacio Lagoon economically and socially. They also benefit the wildlife that depend on this unique ecosystem. The Laguna San Ignacio Ecosystem Science Program (LSIESP) supports the maintenance of a marine protected area in the Lagoon.
Achieving this vision requires a scientific basis for management. Reliable scientific information is fundamental to evaluate development and conservation options, and to assess their effectiveness.
This past winter, scientists from Scripps Institution of Oceanography (SIO), in collaboration with researchers from the Universidad Autonoma de Baja California Sur (UABCS) traveled to Laguna San Ignacio to study gray whale acoustics. Among other goals, heir research aimed to track vocalizing gray whales, to match a particular whale ’s behavior with vocal activity, and to convert call counts into population estimates. Researchers also wanted to be able to measure the behavioral and vocal response of gray whales in the presence of boat traffic by recording their body movements, vocalizations and ambient noise
Searcher Natural History Tours assisted researchers with equipment and personnel transport to San Ignacio. We are honored to play a small role in the research of gray whales at Laguna San Ignacio.
LSIEP’s research is supported by grants and gifts from individuals. To know more about research project results and conservation plans, go to: www.SanIgnacioEcosystem.org

We regularly see two species of oystercatchers on Searcher Natural History trips. The black oystercatcher (Haematopus bachmani) is completely black-brown, and its range extends along rocky shores from Alaska to central Baja California. The American oystercatcher (H. palliatus) has a black head and neck, a dark back, and a white belly. It’s found from central Baja California throughout the Sea of Cortez and the Atlantic and Gulf coasts of the U.S. from New Jersey to eastern Mexico. Populations overlap, and we see them together on Islas San Benito. Because they hybridize, some experts regard them as subspecies of H. ostragelus.
Both species have remarkable bright orange-red, chisel-shaped bills adapted for piercing mussel and clam shells with repeated blows until they make a hole in the shell. Oystercatchers also use their bills to pry limpets from rocks, to stab crabs, and for probing rocks and cobble beaches to catch worms.
They build minimalist nests on rocky shores
and usually lay three eggs, which both parents incubate. As ground-nesters, oystercatchers
frequently lose eggs to other avian predators such as ravens and gulls. The young stay with their parents for as long as a year, learning to feed. They reach maturity in about four years.

Sketching Aboard the Searcher
by Peter Gaede, Searcher Naturalist
Using a sketchbook or journal to record what we encounter during a Searcher trip fosters a unique connection to nature as we make exciting discoveries along the way. Like music, writing and photography, sketching allows us to document events and experiences. This, of course is nothing new: cultures in the past have recorded everything from the passage of time, hunting, battle and exploration. Sea captains have kept logs noting weather, constellations, maps, and the passing of mammals and birds.
I enjoy creating basic sketches with brief notes of certain things I come across, using pencil and sketchpad or watercolors. Often times I learn the most about a subject when I spend time sketching and closely observing: details are revealed and questions form. Slowing down, a greater appreciation, and preserved trip memories are all benefits of nature journaling.
Some of my favorite times to sketch in Baja are when we make our stops on the islands. The desert landscape near the sea, with its unique combination of plants and animals, is rich in natural history and very inspiring. I enjoy offering at least one sketching “class” on a Searcher trip. It’s a great opportunity for those with or without experience to get together and have fun with a sketchbook.
