Why do Nuthatches spread their wings? White-breasted nuthatches exhibit territorial behavior, and when they feel threatened, they may spread their wings and sway. This behavior, along with the distinctive dark-and-light pattern at their wrists, can serve as a visual display to deter potential threats, including other birds. Such displays are common in many bird species as a way to protect their territory. Photo credit to Birdfy user. #Birdfy #birds #birdtips #nuthatch #didyouknow #funfact | Bird
