Nashville Warbler, Boulder County

[Jeff Percell]

I found a Nashville Warbler at KOA Lake in Boulder County when I
stopped there on my way home from work today. I was hoping to maybe
find some interesting warblers -- and was pleasantly surprised to have
at least something other than a Yellow-Rumped Warbler and it was a
special treat to see a life bird. I added several photos to the below
checklist, including ones that show the bird eating the organic matter
being pushed out by the budding leaves of the tree it was in. Thanks
to Dave Leatherman for the encouragement to share additional
information of what the interesting birds are doing and eating.

It looks like perhaps the same bird (or maybe a different one) was
reported further west along Boulder Creek earlier in the day as well.
