If there is a single rule all photo enthusiasts should follow, it is to always have a camera of some kind with you. Photo Ops will present at the most inconvenient times and not always when you have your top gear with you.
Recently, I was passing through Lucchesi Park in Petaluma on a mid morning bicycle ride and noticed a white object up in one of the trees. Upon closer observation I noticed that it was Night Heron that was well hidden as evidenced by the first photo below.
I had a pocket camera with me and realized that I would have to make it do. Fortunately it had the ability for manual settings and I managed to pull off a fairly decent photo. The trick was to maneuver close enough and to force the camera to focus on the bird instead of the branches. See the second photo.
