Willow is a navy blue-colored Bird that first appeared in Angry Birds Stella
Willow is very artistic and loves to daydream. Unfortunately she has grand ideas but cannot always follow through. It aggravates her to see someone destroying her habitat. She is a free spirit but is the shyest of the group. She also feels safest when wearing a large, over sized hat, which she tends to hide under. She sometimes holds back her feelings aside from when pigs are around. She hates it when someone disturbs her when she has a creative art session. Willow appears to be the least daredevil-like of the group; as seen in one of her character sketches, she is dragging Stella by her tail, possibly to stop her from getting into a fight; and the promotional art, she has a shocked look when she sees Luca leaning above the edge of the tree branch.
