 Bohemian Waxwings are subtle. They are often first detected by their high-pitched trill, which is only slightly louder even when several birds are vocalizing at the same time.  Larger than Cedar Waxwings, Bohemian Waxwings are also identified by the rusty brown undertail coverts. |   A few of the Bohemian Waxwings near Heywood Hospital in Gardner March 25, 2015. |
