ECORP Avian Biologists Lead Bird Walk along the San Joaquin River with Residents of Tesoro Viejo: People doing Photography and Research.

ECORP Avian Biologists Keith Kwan and Angela Haas led a birding walk along the San Joaquin River for members of the Tesoro Viejo Community in Madera, California. The 3.5-mile hike began on the Tesoro Viejo Trail and included footpaths along the San Joaquin River Parkway as well as a trail meandering through Ledger Island. The participants enjoyed observations of over 40 species of birds. Biodiversity (and courtship) was on full display, including large raptors such as bald eagle and osprey; many species of ducks and waterbirds that included hooded mergansers, wood ducks, and great egrets; and a variety of grassland and woodland species from Lewis’s woodpeckers to Say’s phoebes to yellow-rumped warblers.

Mr. Kwan is an experienced Avian Biologist whose expertise in the Central Valley extends over 30 years. Ms. Haas received her M.S. studying bird communities of the Central Valley and has been birding in and around Sacramento for the past six years.
