.If there is* babies, I like when they reach for me to pick them up. For hamsters, I like when they let me hold them. In the case of wild birds, it makes me happy when they don't fly away in a panic. If a butterfly lands on me, I feel special. When I come home from work, I like to be greeted at the door.
.As a child, I was fascinated with Saint Francis. These days I do not know how much of his story is factual and how much is legend, but back then, it had a certain appeal for me.
.The birds in my friend's backyard were cautious about approaching the feeder when people walked on the deck, but they kept watch from the other side of the yard. I was able to approach them indirectly, by walking around the swimming pool. Most of my body was hidden, and I braced my telephoto on the edge of the pool. The zoom brought me in close, so that looking through the lens, it appeared that the birds were totally comfortable with my presence. It was an illusion of course. And then, when the opportunity presented itself, they all rushed the feeders.
.* Good catch, Mary. See explanation in comment section.
