    The tamarack does not belong.

    As usual, we are not necessarily sure of some of these (well, clueless in some cases). Here are our best guesses so far:

    A) Black Spruce Picea mariana, or some other kind of spruce. It is not a pine or a tamarack.

    B) No clue. Amanda has some guesses. These are large leaves, by the way, a few inches wide. It is definitely not a Jack-in-the-pulpit. That thing sticking out the top is just another leaf unfolding.

    C) Tamarack Larix laricina

    D) I’m pretty sure this is a bluegill Lepomis macrochirus, and not some sort of hybrid. But I’m open to suggestion. The last fish I pulled out of this spot was hard to classify, so I had the camera ready this time. This is the organism that was not at Itasca.

    E) I like the suggestion of joe-pye weed.

    F) This is a red squirrel, Tamiasciurus hudsonicus. It is interesting that so many people said gray squirrel. I suppose it’s the angle and lack of scale. For gray squirrels in your yard, click here.

    G) This is the immature Wood Duck.

    I should also mention that Lorax was also correct in all of his ID’s.

    B = False Salomon’s Seal (Maianthemum racemosum)

    E is indeed Joe Pye Weed. (Sorry, this is also a bad spoonerism, but to my defense I have a probable hereditary condition that keeps me earing spooners the wrong way, just like some are typoing most common words all way down :).

    Thank you Laurent!
