  We have been feeding the Song Sparrow in front
of the cabin with hemp seed & one or two are there
most of the time. There were two together this morning.
As I was watching them a female Robin approached them
gathering strands of dry grass for her nest. Suddenly
one of the sparrows attacked her with a vindictiveness
that I have rarely seen equaled. He flew straight at
her and seized her throat feathers in his bill hanging 
on like a little bull dog. This was repeated three times
the Robin resisting without much spirit, however - &
flying further & further away after each onslaught.
After she had departed altogether the Sparrow returned
and began quietly feeding again.
