Feathers with dry blood inside the shaft. (a) The blood is located from the superior umbilicus to the distal portion of the rachis; (b) the blood is in a small section of the rachis, from the superior umbilicus to the distal part of the rachis; (c) the blood is only observable at the distal portion of the rachis. Bracket and arrows indicate blood’s location.
