觀察細節
I believe it is of the Eastern subspecies. I first identified the bird by song as I was walking up the east pier on the east path around 100 - 150 north of the north end of the marina. It sang about 5 times in rapid succession, paused for several minutes, and sang again. On the third round of it singing, as I was trying to record it, I finally spotted the bird about 30 cm off the ground in some shrubbery. I took a few record shots than watched it for about 1 minute through binoculars as it moved through the shrubbery and a brush pile. Overall a small slim vireo, greenish olive in colour with some yellow along the flanks. The bird had an obvious lower wingbar and just a hint of an upper wingbar. It had a grayish - olive head with faint spectacles. The song was distinctive - a very fast scratchy song that goes up and down in rapid succession - like taking a Sharpie marker and moving it quickly on a whiteboard. There was a gap of about 2.5 hours with no more sightings, then at 12:40 Frank Pinilla and I heard it sing twice from the same area but were unable to get a visual. First record for the BOS area and second for Niagara Region. Accepted by the Ontario Bird Records Committee.
