Dan will discuss the unique life history of this largest North American swallow, its history in Solano and Napa Counties, differences between the eastern and western subspecies, and current threats they face. He’ll present an overview of the status and conservation issues facing the species in California. 

He will also provide preliminary results of the 2025 statewide Purple Martin breeding population survey.
