Heard-only grosbeaks

7:36 am

There have been a number of reports the last 2 or 3 days of the known male Rose-breasted Grosbeak at the Bird and Butterfly Garden but some of which are of heard only. There are, of course allso multiple Black-headed grosbeaks singing there, and Merlin does a poor job of differentiating the two, sometimes identifying a singing Black-headed as the Rose-breasted and sometimes going back and forth on the same song calling it Black-headed one time and Rose breasted the next. So please for all reports of this bird, please get a visual as well.
