It’s a hot summer day, there isn’t a breeze blowing and everything is still and oppressive . . . except for one bird that is singing over and over again . . . as many as 20,000 times in a day.

We hear the Red-eyed Vireo sing so often, a whistling phrase “here-I-am, in-the-tree, look-up, at-the-top”, that we completely tune it out.

The five other Vireos we hear in Maine are just as boisterous, just not as common.
