The collar is squirrel tail. Ive been using it since last year, I prefer it over bucktail because its less buoyant and water seems to make the squirrel pop and prop the desired materials that need it.

No rhea used in this intruder, mostly ostrich herl. Theres a few strands of dyed peacock tied in reverse in the tail to help prop the ostrich in the tail. This was first of probably many of this pattern. I'll need to see how it swims first before it gets mass produced.
