Ron,
Take your feeder and and hold it away from you a little and put your finger on the perch and be still as possible when they start getting close..Once they earn your trust they will land on your finger if you keep your thumb and middle finger on the other perch's best you can ...Hold it liker a person would a wine glass...I used to do this all the time and then had my wife join in...It's the lightest thing you ever felt and once they start resting on your finger you can entertain children and guests as they stop by..Somewhere I have some pics of me with humming birds resting on my finger my wife took about 9 years ago...If you do get them landing then it's a shure thing to get yourself a Hummingbird bow....Just think of them as little salemen telling you to order a new bow..
