MAPS Songbird Population Study
MAPS - Monitoring Avian Productivity and Survivorship - is a continent-wide breeding season study started in 1989 by the Institute for Bird Populations in Point Reyes , California
Sanctuary volunteers and staff initiated the Jug Bay monitoring program in 1990, making our bird banding station one of the oldest, continuously operating stations in the MAPS program. Every summer during the breeding season we operate 14 mist nets in our study plot in order to capture songbirds which we identify to species and then determine their age and sex. We make standard measurements of wing cord and weight for each bird, and place a USFWS band on the leg of each bird so we can identify it if we capture it again.
Volunteers who help with this study will learn how to operate mist nets, remove songbirds from the nets, and will learn how to collect measurement data, and to identify and sex dozens of species of songbirds.
A general description of our study and how volunteers can help is available here. Sandy Teliak prepares summaries of our weekly results as well as a year end summary. To see his summary of the 2009 season, click here.
We have banded over 2,400 birds. Click summary to see the banding results of our 20-year study.
