That’s not my understanding of the feature at all, and that’s not what a relevant Help Center article says:
Wyze Cam Pan v3 is equipped with a starlight sensor that allows the camera to see color in extremely low light conditions, allowing you to see full color at night. It works best to use this feature in low light settings, by turning Night Vision off.
This topic might shed some light (pun intended) on the situation for you, as well:
When that available light is none (or close to it), then I don’t think “color night vision” is going to work. That’s when I would expect the camera to use regular IR-based night vision if Night Vision Mode is set to Automatic.
I understand your concern about the birds, and I think that’s completely valid. It’s actually really cool that you’re taking their health into consideration like this. If you really want color video, though, then I think it’s going to be necessary to increase the available light for whatever viewing area you’re trying to capture. It doesn’t even have to be a lot, based on my experience: With my Cam Pan v3s that I use indoors, I have regular plug-in night lights in that room that turn on (via smart plugs) and off based on routines that are tied to sunset and sunrise times at my location, and I’m pleased with the color views I get. That’s why I mentioned earlier that getting the color view might require you do experiment some with adding light to the scene. Barring that, you’re probably going to want to use the regular monochrome night vision, which actually looks pretty good based on the photos you shared.
