Hey Lars,

Yeah. Yesterday morning I heard a Northern Parula song about six times on
Warrior Point Trail. I heard it on the walk out and thought I was hearing
things and wrote it off as something else but on the walk back it did the
full single buzz upwards with one note after. I couldn’t ever get my eyes
on it, but then I also couldn’t get my eyes on nearly anything else in the
canopy. I also unfortunately didn’t get a recording as by the time I got my
phone out it stopped singing and the mosquitos were intense. I sat there
eaten alive for over 10 more minutes before leaving.

Hopefully someone else heads that way and can find it. By the time we were
leaving the trail was getting pretty busy and not everyone was wearing

Given the actual sightings etc., The other Parula sounds like a much safer
bet. Weird that that occurred on the same day. I didn’t see that report
until we were back. In any case, I completely understand if eBird doesn’t
accept my sighting as I have no good evidence. Wanted to put it out there
in case someone else nearby can find it.
