Not yet identified (likely new species; Bldg. 4C).  All this rain definitely doesn't help with feather ID.

Yellow-rumped Warbler (aka "Butter-butt") (2B). It looks like this bird hit my office window.  Just a few days ago I was watching one of these guys in the tree outside my office window.

I found this stunned Ruby-throated hummingbird today. I also watched it die. I sat with him for 1 1/2 hours hoping he would pull through, but unfortunately the collision with the window was too much for this little guy. This work doesn't get easier, but like my aunt just told me yesterday... we have to "keep it up for those beautiful birds being lost every day".

And for whatever it's worth, it helps me some to know that these birds are documented.  That their short time on earth was captured (even if by this piddly little blog). That someone cared that they died and hopefully their deaths won't be for nothing.

Ruby-throated Hummingbird (11B).
Hummingbirds can fly across the Gulf of Mexico in a single flight.  This male made it all the way to Virginia from Central America to die at a window.

We are anxiously awaiting the arrival of the warblers, one of my favorite groups of birds.
I saw this on Maryland Birding's facebook page. Very creative representation of these sometimes tricky little guys.
