Bring a chair and let’s observe all the birds we can between 8 a.m. and noon while sitting and standing within a 17-foot diameter circle. Possible species include sparrows, warblers, and hawks. Drop in for an hour or stay for the whole time. We will cancel in case of rain. Leaders are D.C. Bird Alliance’s Maria-Elena Montero and MBC’s Cheryl Hogue. Direct questions to cheryl.hogue@gmail.com
