With heavy snow on the ground, many birds are having a harder time than usual finding food.  Bird feeders offer easier pickings for some species.  Carolina Wrens are showing up at suet and peanut feeders. Tufted Titmice will visit seed or suet feeders and are being seen in higher numbers than normal this winter.  Look for sparrows feeding on the ground beneath feeders.  If you live within a Christmas Bird Count circle, keep track of the birds you see at your feeders on count day!
