Odd bird
Milton Glaser Collection. Drawer 21, Folder 11: poster for Poppy records, 1968.
Looks like a regular ocellated fellow, with one significant difference. Cross-reference for flowers sprouting from heads: Utopia Records, and this poster for Push Pin Graphic. (Typeface is Glaser Stencil, which appeared on other Poppy productions as well.)

Comments
There’s also a floral bird (but not just the head) on Glaser’s second poster for the Temple University Music Festival.

Yep, this one
And also: bird head on human head variation.
