I'd argue that, based on what this paper is discussing at least, it'd be pretty impossible for them to use stars to navigate. I'm not sure what they'd do in pitch dark environments but if they're using either the sun, moon, or artificial light to help them navigate, I highly doubt stars would even register/be detectable to them.
