Join Bob and Juli for a walk in the best grassland habitat at Hayward Regional Shoreline, "Mt. Trashmore," followed by a visit to "Frank's Dump," a favorite high-tide roost for shorebirds. November is a good time to look for elusive Lapland Longspurs and Aleutian Cackling Geese, and see many other grassland and raptor species on Mt. Trashmore. We'll visit Frank's Dump as the tide rises. Bring your scope if you have one, and wear comfortable shoes for a fairly long, though flat, walk.
