Great Meadows

Spent two hours at Great Meadows this morning.

First good sighting was a Yellow Warbler.  Like the bird pictured, it did not have the rust colored lines on its chest.  A fellow birder, much better than I, confirmed it was a yellow though.



Next up was a close-up view of a Rose-breasted Grosbeak.



Then, again with the help of the same fellow birder, I ID'd a Warbling Vireo.
(A little boring to look at honestly).




On the way out, I'm pretty sure I saw another Yellow Throated Vireo.  It was in the tall grasses on the water's edge.  It seemed a little duller that this picture.  And I'm not sure if I saw the white.




could it have been a Pine Warbler?  Are these really pictures of two different birds?




Is there another choice?  I'm not sure anymore what I saw.
