So I waited for an hour for the kingfisher. Saw 3 species of kingfishers (Ringed, Green, and Belted) while waiting, plus Colette Micallef's excellent video of the Amazon. And, I got to see the Amazon's haunts (on halloween) ...
I photographed a Ringed Kingfisher from quite a distance away.
I may have waited longer for the Amazon (it showed 1½ hours after I left) but my car's engine was missing and at some point the stress of delaying my trip longer canceled out my desire to see the bird.
Safely home after a wonderful trip. Hindsight is always better because the stress is gone. Car headed to the shop early AM.
