Thanks! WesternGuy, I found that the key to catching the perched ones is to observe them for long periods of time and find out their favorite spots. They will tend to land on the same spot over and over before coming down to the feeder. It is an instinctual thing I guess to look out for other hummer or prey birds. Once I found this spot, I placed my camera on a tripod, measuring my minimum focus distance away from this spot, then just waited. I pulled off hundreds of images from this one perch, but the "money shot" for me was this one, where the little guy had his feathers all puffed up.
