1/40 and handheld. Good thing my lens has IS. I did have my lens hood against the glass, though. It was so dark in the enclosure that I could barely see this bird and only caught a glimpse of another one. It's also good that my lens has good low-light auto-focus, too, because he was just a silhouette to the naked eye.
The red reflection in his eye was from the heat lamp.
