Bird blood

Blood from a dove.  Birds' red blood cells have nuclei, unlike the red blood cells of mammals, which do not.  60× objective, 15× eyepiece.  Numbered ticks are 20 microns apart.  By the way, the bird is OK.  I was alarmed to find her bleeding, but her injury turned out to not nearly be as bad as it looked.
