Getting close to a source for f85r2

[R. Sale]

The proposed similarity of the two birds is apparent, even though the comparative parts seem to differ in many aspects. The beaks, hooked or not. The eyes, a circle or just a dot. The bodies, stippled or marked by four rows of indented lines, The wings, feathered only on the bottom edge in the VMs or separated and feathered on the sides. The tail, spread out or confined.

Is the bird 'swan diving' into its hood? 

The object he is holding looks like an eagle's leg erased in the heraldic references.
