Bell's Vireo (Eastern)
Published in NAB. "Acceptable description". "Apparently the Eastern subspecies....The grayer California birds...would be far less likely in late spring at Pt. Reyes". My [LQK] general impression of vagrancy patterns agree with this: Western vagrants often come through earlier, maybe early May-Early-mid June but eastern vagrants tend to be the ones that linger into late june/july.
Are you submitting a complete checklist of the birds you were able to identify?
