The phrase "her barred face identity mask" refers to the distinctive barred or striped pattern on a bird's face that acts like a mask, serving as a unique identifying feature for the bird. This "barred face" functions as an identity mask because it marks the bird's face in a way that makes her recognizable and distinct, even as she remains hidden in the foliage or "thickness." Essentially, the barred pattern on her face symbolizes her identity and is like a natural mask that both conceals and reveals who she is
. In a metaphorical sense, the "identity mask" can be understood as the outward appearance or markings that express the bird's character or identity, much like how a mask can represent or hide a person's true self
