Any more recent pics. your latest male doesn't seem very obvious to me imho
i agree.
But having them to observe everyday, they show their colors. females usually pick a spot and stays around there being yellow. Males roam around in grey. But yes if I dont see it that way then we need more time to confirm for sure gender of course.
