1. I called this a Double-toothed Kite.
2. And this was my Eastern Wood-Pewee
2b. but in case that doesn't work I have a backup. A very tiny backup.3. This one has evaded all my investigations.
4. A mysterious bird. It may have had a nest hidden under the plant.
5. My favourite unidentified bird. I know what I want it to be. It was taken at 2 in the afternoon in a valley in Eastern Ecuador along a highway near where we had just watched several Swallow-tailed Kites dipping and gliding.
And that, I promise you, are all the mysteries from Ecuador that are worth investigating.
