Birders often gravitate to wastewater treatment ponds because they know good birds are to be found there. The 20-acre freshwater marsh / pond at Las Gallinas has water up to 6 feet deep in the center, and several small islands that give some security to nesting and roosting waterfowl. Storage ponds numbers 1 and 2 fluctuate in level because of water management requirements. There are open views of bay marsh to the east, all the way to Mount Diablo. Mount Tamalpais looms over the ponds just to the south. Specialty birds: Resident—White-tailed Kite. Summer—Cinnamon Teal, Elegant Tern, Allen’s Hummingbird. Winter—Western and Clark’s Grebes; Eurasian Wigeon; Long-billed Curlew; Mew Gull.
