I think a second bird started singing at 0:09 with two notes overlapping the original bird.

观察细节

One bird heard singing, then two adults seen briefly foraging somewhat together about 75-100 yards south of the parking lot along 73, mostly favoring the pond side. The philly's song differs enough from the red-eyed that it can be picked out somewhat easily (if traffic on 73 isn't too bad). Compared to the red-eyed's clear, emphatic and evenly-spaced "here I am, where are you", the philly's song has weaker, almost half-spoken phrasing with longer pauses in between. In the first audio, I think a second Philly vireo slightly further away might have started singing at the end - there are two notes at the end that overlap with the original bird. So possibly 3 Phillies. Audio was tough as the road is busy and red-eyed vireos were louder and there were some noisy ravens nearby.
