Are they a guide? Companion?
For me birds are companions. Well my Cocketiel is. She can be annoying but most of the time she's affectionate with me and that cheers me up. Other then her i've been visited in my dreams. A Great grey Owl and a strange mutated penguin. The owl was a one time thing but it stuck with me. Penguins are another story randomly showing up like once a month.
