California Partners in Flight is participating in a Yellow-billed Magpie Working Group. It is generally accepted that Yellow-billed Magpie populations are declining since the arrival of the West Nile virus (WNV) in California in 2004. To better document and understand magpie population trends, the working group is recommending that censuses at communal roosts should be conducted throughout their range as well as nest monitoring when feasible. We need the help of volunteers to collect these important data. More information can be found at: Please consider participating in this monitoring effort!
