LOL Leonard, I have two humming bird feeders. One on the front porch and one on the back porch. There definelty is a king of the hill going on..
The one in the back has a humming bird with green and red ring around neck. That one is master of the feeder..
I have seen five humming birds trying to get to the nector and he will chase all of them off.
On the front porch we have about four regulars and it is a riot to watch them try and get some nector. They get very close to us when we are sitting on the porch watching. Buzz right over our heads chasing each other....
I am also facinated by watching birds dive bomb the local tom cat..
That tom creeps accross the yard to get accross the road hoping the birds don't see him.. lol.. I watched the birds terrorize that tom cat one morning for about 1/2 hour before the tom cat could find cover under the next door neighbors house.. Very Funny to say the least..
