I recently received a brand new field guide from my old friend Richard Crossley about the identification of ducks and geese, so, before I tested out the Crossley ID Guide: Waterfowl, I headed to the nearest duck pond I could find to see who was available to model. There were plenty of Canadas floating serenely in the duckweed, and a pair of more-or-less off-breeding plumage Wood Ducks, both of which I'd know in my sleep. But there was also a non-Crossley bird—well, for the new guide; it was covered in an earlier Crossley ID book on birds in general—and while I also knew its identity as a Green Heron, I wanted to watch it at work for a while and, perhaps, get some decent photos, since I just happened to have the 150-500mm Sigma supertelephoto on the dSLR. The heron was wonderfully cooperative, and I had some handy fence posts in the right place to use as lens stabilizers. Alas, I missed the heron's dive into the water to snare its prey, but I was faster on the draw when it emerged with a fat tadpole, either a Bullfrog or a Green Frog. Impressive angling, albeit not a good day for a young batrachian.
