Philadelphia Vireos in Spring

By mid to late spring, the underparts of Philadelphia Vireos can be quite faded. The vibrant yellow tones quite often typical of fall birds fade to a fascinating creamy yellow by spring. In some cases, an isolated yellowish wash occurs on the throat and breast followed by a mostly whitish underside; this combined with the grayish blush to the crown; arcing white brow; and blackish wedge to the loral area provides a beautiful example of subtle beauty. I cannot wait to enjoy some springtime Philadelphia Vireos at Point Pelee in a few weeks time.
