Fellow birders, I am wondering whether the remarkable abundance of Rose-breasted Grosbeaks is widespread this spring. As I type this, I have four adult males, two females, and two juveniles at my feeders, far more than any previous spring. Other birdwatchers here in Granville (central Ohio)are noticing an increase as well. Is this true of other regions of Ohio? Also, why would this surge in the numbers of this delightful species occur? Is it a cycle of some sort, or certain food/weather conditions? I'm really interested in what might be causing this.
