Young Swallow on the Road

While driving the auto tour route of the Ridgefield NWR, July 16, 2014, I approached this young Tree Swallow hunkered down on the gravel road in front of me.  I had to steer around it when I passed and expected it to fly when I did.  Checking my rear view mirrors, the bird was still there.  When I came back to this location on my next loop the bird was still there.  This bird either really liked sitting on these warm rocks, or it was ill or injured.  I stopped near the bird and got out of my truck.  It did not appear distressed and its only movement was to look around turning its head.  I slowly got down low and took this shot from about 15 feet.  On my next loop, the bird was gone.  Hope this little one is okay.   Canon 5D Mark III, 1/1000, f8, ISO 800, 500mm.
