Last New Species post for North Pond - 5.10.10

So I thought I was done with new species for this trip, but then I started going through the shots I'd oh-so-cleverly labeled things like "CheckThisBird" and "UnknownSparrow".

 The first thing I found was this dragonfly wheel.  Unlike the pondhawks I had a ton of last year, this is apparently a Common Green Darner.  He's different because instead of having a solid, dusty, light blue tail, he has a darker green tail with brown marks on it.  He's also *huge*.

 After a few hundred painted turtles, I finally found something a little different.  This is apparently a False Map Turtle.  According to Wikipedia, When with other turtles, they also are very communal, sharing space and using each other for predator watching, increasing the odds of surviving an attack by any unwanted animal. Which explains why every time I saw one of these, they were hanging out with the bigger, more obvious, painted turtles. :)

Like this:

 A False Map hanging out with a group of Sliders.

 Not a new species, but in case you haven't noticed, I find sexual dimorphism fascinating.  This is the female Common Yellow-throat Warbler.

 The folks at the fabulous Project Noah site had to help me with this one.  Turns out he's a Lincoln's Sparrow.  They migrate through Chicago, but apparently don't stay.  So I was lucky to catch him as he passed through town.

 Here you can see his identifying head stripes a little bit better.

 This one is still throwing us for a loop at Project Noah.  He's a wren.  We know that much.  The white eyestripe makes me think he's a Carolina Wren.  But the Carolina Wrens have a very white chin, and this guy doesn't seem to have that.  The Marsh Wren is similar in coloring, but doesn't have the white eyestripe.  Any suggestions gratefully accepted! :)

 Another view, in case it helps. :)

 Something else that needs an I.D.  It's a beetle.  It was digging around in the bark chips on the path of the North Pond.  Any ideas?







Okay, so, I'm not entirely sure what they all *are*, but there's five new species in this post.  So now I'm at 28 of my 50, and the butterflies and dragonflies and most of the cold-bloodeds haven't really started making an appearance yet.  I may have to up my goal. :)
