10th Annual San Francisco Bay Osprey Days will take place at the Mare Island Shoreline Heritage Preserve and other locations throughout Mare Island in Vallejo. Mare Island is teaming with recently fledged young osprey in the sky and perched on high spots in the vicinity of their nest sites. There is no cost or preregistration required to attend the in-person field trips and zoom presentations. Two-hour guided boat trips departing the Vallejo Marina are $45 per person and do require advanced registration with Dolphin Charters.
For Reservations: call 510-527-9622 or 800-472-9942

The free event features numerous car caravan and walking tours scheduled all three days led by field guides from the local Napa-Solano Audubon Society and the Golden Gate Raptor Observatory, other naturalists and the Mare Island Heritage Trust volunteer team.
