Hummingbirds are emptying out the feeder quicker than ever....so pretty. One dominant male sits on top and chases the others away. Just in case you have squirrel issues with your hummingbird feeder, I tied a Slinky (Walmart) at the top of my Shepherds Hook and it flows down from where I have my feeder and the squirrels cannot climb up the hook anymore and empty out the hummingbird feeder. Works like a charm!
