Does anyone know if it is possible that RB Nuthatches will breed in Montgomery County, MD? There is a pair that has been frequenting my feeders for the last 3 or so weeks and I was wondering if they might stick around for the summer. The Yellow Book doesn't show that RB's breed in this county. Are there any records of this happening? Thanks, Andy Rabin Gaithersburg, MD andyrab@wam.umd.edu
