I have heard/read conflicting ideas over the years about adding additional feeders to try to break up the aggression:  one theory is to have feeders out of sight of each other, the other is to have them relatively close--the thought being a territorial hummingbird can't simultaneously defend both feeders.  
Anyone have any factual information on adding feeders??  I currently only have one hummingbird feeder.

There was an over-wintering Rufous Hummer near Port Townsend that was killed by an Anna's a few weeks ago. When the Rufuos was present, a dozen hummers would share the feeder. After it was gone, the feeder was ruled by a single Anna's.

Dayna,

Over the years we have seen hummingbirds do a lot that appeared to us as
strange.  But, this morning, I saw an adult male Anna's attacking a
younger (hatch year probably) bird on a feeder.  The feeder has been
defended by the adult for months, but I had never seen it do this.  From
my view in the kitchen at about 8am this morning, I could see the
adult's head on the opposite side of the feeder, but could not make out
what it was doing.  Walking around to another window though, I could see
it was on top of a younger bird beating its head with its beak.  The
immature bird was not moving or defending itself.  I opened the back
door about, 4 feet from the feeder, but the adult ignored me.  The
feeder is not in a position that I could reach, so I went and got a yard
stick, and used that to gently lift up the tail of the adult, which
startled it, and broke its grip on the smaller bird.  But the smaller
did not move.  I did the same thing with the yardstick to it, and it
finally took flight, with the adult in pursuit.   Shortly, the adult
returned.  Hopefully the younger one found one of our other, less
defended, feeders.

We've seen mating, it is noisy, but very brief, generally with the two
birds spiraling toward the earth or into a bush.

It has been years since I thought about Ardrey's "amity-enmity
complex".  Where, at one point, he proposes that environmental hazards
might promote cooperation (amity) among a given species, here it seems
we may be seeing it doing just the opposite.  Well, unlike penguins,
hummingbirds live relatively short solitary lives, and they are fiercely
territorial.
