Could you find some videos for those cases? Would be interesting to see this in action.

Convenient and good infrared video for all these scenarios is hard to come by but would be useful. I think if the DoD was willing to put some money into the budget for practical recreations of UAP scenarios that they then make public, they could do a lot of good. But there'd probably be pushback about wasting money and also risks of leaking information about military sensor capabilities.

But here is a paper showing penguins photographed with a temperature-sensing IR camera, showing the majority of the surface of their body being around -21ºC thanks to the highly insulating plumage.

Good find, but I suspect that's quite a rare case - penguins have unique plumage and are also -- ahem, "quite flightless". It might seem I'm splitting hairs (or feathers!) but the "cold white dots" were quite uniform, these cuties are clearly hot/cold patterned - still a good example, bar the flightlessness.

Please tell me your feelings on the big picture. I feel it's imbalanced if you provide such certainty to some examples but refrain from a larger perspective. It's okay if you don't want to tho, I just want to know where you're coming from I guess.
