Java Sparrows in the front yard

I've got a bird feeder in my front yard and whenever I fill it up, it does a pretty brisk business.  It usually gets a few Red-crested Cardinals, the occasional Northern Cardinal and a bunch of House Finches.  But mostly it gets whole flocks of Java Sparrows.  Sometimes I'll grab my camera and sit on my porch just a few feet away trying to get good shots.  This morning I ended up with some good ones.
