During our Sunol Wilderness Regional Preserve birding walk, you will observe winter species returning to the area. We will spend time learning to identify these birds by their field marks, focusing on east-west migratory species, such as Red-breasted Sapsucker, Pygmy and Red-breasted Nuthatch, Say’s Phoebe, Pine Siskins, and wintering warblers.
