Personalities of all sizes

Having watched the generations of animals that have inhabited our yard I notice behavior differences among individuals. Often that behavior reflects their tolerance of humans.
In the past we have had resident humming birds that used the feeder outside the kitchen window no matter what we were doing at the sink. In fact at one point one was so used to me that even when I was outside within 3 feet of the feeder it would feed readily.
Our current group range from shy to downright skittish. The female in the picture above is the least wary. She will use the feeder if we are still, but much movement will drive her away. The rest of the several that use the feeder will barely tolerate our presence in the room. As a result the kitchen blind is frequently closed when we should be enjoying the view.
