I recently returned from a trip to south-central Oregon. I photographed
two different Yellow-rumped Warblers (YRWA) that I thought might be
intergrades as they seem to have some characteristics of both Audubon's and
Myrtle forms. I would be interested to hear other's opinions-intergrades
or just within the normal variation for this species? Here is a link to
the photos on Flickr:
