As far as I can tell, folks use "mounts" and "taxidermy" somewhat interchangeably. Yes, the Science Museum of MN, and the Bell Museum at the U of MN have wonderful collections of bird and animal taxidermy (or mounts).
As I was drawing, I was thinking about Primary and Secondary feathers and their coverts since I now comprehend those parts. I had been wanting to call coverts "coverlets" as in a bedspread since I was confounded by the somewhat negative meaning of the adjective "covert". Now, with the help of my dictionary, I can think more positively of a bird's covert feathers as "sheltering" the quills of its wing feathers. For the rest of the parts, I used the Laws book that was sent to me from the Week 2 drawing. There is so much detail in his book about the way feathers are attached to the various limbs of a bird, and overlap the various parts -- almost like scales -- except that birds can manipulate these so gracefully -- to fly but when perched. Truthfully, I never thought much of how a bird's skeleton fits within its body -- especially how its neck, with its greater number of vertebrae than us primates, allows for such dexterity of movement of its head up and down. When I'm cold, the most I can do is to scrunch up my shoulders and zip up my collar. How wonderful it would be to be able to draw one's head in closer to one's body!
I labeled the area of the what I thought would be tertials. Without knowing what to study in detail, I was largely drawing what I saw. Tonight I'll study the Bell Museum's dioramas to see if I can differentiate tertials and the other feathered parts from one another.
My compliments to the PFW: Sketch program for providing the opportunity to connect what I've been seeing and studying at the Bell Museum's monthly Sketch Nights for the past year with the anatomy that underlies the outer form of our feathered friends!
