Extraordinary Display

I've had two hummingbird feeders out all summer.  I feel like I've been feeding every hummer in the county.  We've gone through at least 25 pounds of sugar so far.  

This feeder does not get the attention the other feeder gets and I don't know why.  Maybe it's because the other feeder is more in the open.

I've seen as many as eleven hummers trying to sip from this feeder at the same time.  They are like jets zooming around the patio and yard.  After filling up, they hang out in the tree until they need another shot of juice.

How many do you see in the tree?
