I make mine that way too...it is a little stronger than the recommended
1:4... but my vacation birds love it that way. I don't boil it however. I put in some commerical food
with ascorbic acid to deter mold. I don't get much mold if any since the feeders go dry so fast.

My feeder here has less action and no displays.

But up north, from which I have just returned today, there is alot of
"hoarding" of the feeder. Over the years I have learned a couple of things.

1) if you are on a highway for migration, then all sorts of territoriality can happen.

2) the young birds fresh from the nest, play alot. Swoops, dives, chittering,
etc. These birds have short beaks..check out my pictures in the photo gallery for a baby example. I used to think these were "fights"... but now I think they are just having fun.

3) I have had mature males travel thru and take over a feeder however, and chase others away. These have the typical red throat.

I have minimized the frictions by putting up several feeders and placing them where they are out of eye line sight of the "territory keeper" and that works too.

This year it was quiet in our bay, not many homes across the water were
occupied...and hence we had only a few hummers this season. I have had many many in the past tho....up to 20 at one time in our front and back yards. We live on an island, so they fly over. This year we got to see them dodging HAWKS...that was a sight...whew!
