Pose and silhouette hierarchy
A bird stencil reads first as one body angle plus one silhouette cue: spread wings and tail fan for flight, folded wings and upright breast for a perch. Species follows from beak shape, tail length, and leg posture, not from feather texture. Stencil viability comes from naming the pose and the species cue before judging any feather, because photo reference shows layered barbs and soft overlaps that merge into one band on skin.
Check: Cover every feather row. If the bare body angle plus beak direction and tail shape still reads as the intended bird at a glance, the hierarchy is sound. If removing texture leaves an unplaceable generic shape, lock pose and silhouette before touching line weight.
