I saw there was a sparrow visiting a feeder, so I sat in a chair about 30 feet away, with the sun at my back. I took various shots of the feeder, trying different modes (manual, shutter priority, etc.) and ISO levels to optimize the light. I waited about 30 minutes but the bird didn't return. I was too close and too obvious. Although I moved some, I didn't make any sudden movements. It gave me a sense that I need to work harder to get well positioned.
