Definition Of Shaking
This is a vague term requiring more explanation. If birds are shaking out their feathers, then they are rearranging them as a grooming function. Falconers say such birds are rousing their feathers, and parrot owners often call this fluffing the feathers. Feather rousing can also be a happiness behavior, as parrots such as African grey parrots often rouse their feathers and wag their tails when greeting a beloved friend. As post bathing shivering, a wet bird might be chilly. If ambient temperatures are warm, shaking might be a reflex that encourages the shaking out of down feathers to speed their drying. Depending on circumstances, shaking might also indicate a bird feeling stressed or anxious.
What To Do
As a post-bathing behavior, nothing need be done. If shaking is associated with anxiety or stress, those problems need to be addressed.
