I stumbled upon a bunch of ducks contently lounging about and it's not clear who was more frightened! I did remember to keep shooting as they lifted straight into the air with pond water raining down from their bodies.
After that episode I walked across the road to the lake to come upon a couple of Double-crested Cormorants floating about. Shortly after spotting me, they were off as well! These are a new ID for me, never ever seeing this species on the lake or anywhere else for that matter.
All these shots suffered from my surprise and lack of proper bird lens--the 100-400mm left behind on my couch. :-)
