Similar species and how
were they eliminated:
I recognized the distinctive call when I heard it as something different. I waited up to ten minutes before getting the first glimpse of the bird as it sang constantly from within the dense vegetation. During the first few minutes of listening to the call, I began to suspect it was a White-eyed Vireo. I am familiar with the call from tapes and previous experiences. No recording was used to bring the bird into view. I did not want to scare the bird away. When the bird finally came into view, my suspicions were confirmed. No other vireo has a gleaming white eye.
Previous experience with
this & similar species:
I have seen several white-eyed Vireos in NE, IL and FL.
