The Bill of a Purple Finch

| View Cart ⇗ | Info

“Carpodacus. Purple Bullfinch. Bill smaller and less turgid than in Pinicol or Pyrrhula, more regularly conic and more acute; sides convex in all directions, but with distinct ridge prolonged in a point on forehead where not concealed by the antiae, its outline moderately curved; commissure decidedly angulated, about straight before and behind the bend; gonys quite straight. Nasal ruff little developed, barely cocealing the slight nasal fossae, thence falling over sides of bill, but discontinuous across culmen.” Elliot Coues, 1884
