Experienced birders have been fooled by this little charmer’s varied songs. The OATI’s silhouette, however, is unmistakable in our area, with a topknot that is always on display. A somewhat furtive bird, the OATI will visit a feeder, grab a seed and take off with it while other visitors stick around gorging themselves. If you put up an appropriate nesting box, there’s a pretty fair chance of attracting a breeding pair.
