It was in early evening and I wasn't quite sure how clear any picture would turn out -- even after raising my camera's ISO setting as high as I dared (ISO 1000) without beginning to see noise artifacts. I walked out into the backyard, then slowly approached a sago palm that grows next to the clothes line. I got to within a few feet of the hummer on the clothes line and took a lot of shots. Most of them were no good, but I liked the look of the following pictures:
These are all close crops of the original images, so it looks like I'm much closer than I really was.
The mating behavior continued on all day today. I suspect we may find a nest in the near future, which would be too cool.
(Shot with the Nikon D300 using the 70-200mm VR zoom; aperture-priority, with aperture set at f/4; camera chose shutter speed of 1/100 second at ISO 1000; center-weighted metered; -0.7 exposure compensation; auto white balance; normal JPG.)
