Friday, June 21, Saturday, June 22 and Sunday, June 23, 2024 the 12th 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 San Francisco Bay’s epicenter of osprey nesting. By late June, it is expected to be 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. Details can be found in the PDF attached, posted  San Francisco Bay Osprey Days
