Distribution and Abundance of Southwestern Willow Flycatchers (Empidonax traillii extimus) on the Upper San Luis Rey River, San Diego County, California—2023 Data Summary
The complexity of global anthropogenic change makes forecasting species responses and planning effective conservation actions challenging. Additionally, important components of a species’ adaptive capacity, such as evolutionary potential, are often not included in quantitative risk assessments due to lack of data. While genomic proxies for evolutionary potential in at-risk species are increasingly available, they have not yet been included in extinction risk assessments at a species-wide scale.
Evidence of honest signalling in a suboscine bird: Southwestern willow flycatcher song frequency is positively related to apparent reproductive success

This guide, authored by RiversEdge West's, John Leary, explains how to make seedballs and how to plan seedball making and dispersal events. Seedball events are low-cost, engage with and educate community members and support restoration efforts with revegetation.
