More flowers and insects at McCarthy Woods

Here are some photos taken today.

White-throated Sparrow (Zonotrichia albicollis) near the feeder at the place where I live.

Signs of Spring - native flowering plants and bees

After yesterday's post about the emerging plants seen last Monday at McCarthy Woods, I decided to go there after school today (and before I mailed my tax forms) to see if the plants started flowering yet.  And indeed they were (but in very small numbers)! 

The first thing that caught my attention was a wild Nomada bee (as oppose to the honey bees observed more than two weeks ago) with yellow pollen on its body!
