Identifying Characteristics:
Very windy and bad back-lighting along the canal. At the LatiLong indicated, there were a dozen or so birds in the short 10' trees next to the canal. I noticed a bird with wing bars and a bright eye ring. I yelled to my dad "There is a weird warbler with wing bars, get a photo!" Delegating the photo task to Mr. Mike, I focused on getting an ID. We both moved to the left get a better angle with the light, and the bird popped out into the open for about 5 seconds in much better view. Pale below, greenish yellow wingbars and upper, bold eye-ring. My dad was able to get one very poor photo, but you can see a bit of the color on the nape, wing bars and pale coloration below.
