1. Interesting discussion - hummers, ofc, are deceptive because of the appearance(s) of iridescence. I don't know what this one is, but I'm in agreement with the dissenters, though vaguely.
2. I can't find an image (nor, from life, because I only ever saw one, and that, to be honest, was because a local guide called it) that shows Great Sapphirewing
3. That said, the contra-indications are also contra-indicated, but then you're getting into violet versus blue and shoulders versus flanks, colour-wise, and iridescence complicates things significantly. Minefield.
4. So, I don't know (still.)
5. All that aside, that is a lovely shot - light, flowers, etc. That's my best take on this.
6. Any local ECU birder would surely end this banter with an authoritative call?
