Feather in your bonnet

[JohntheBiker]

There are Canadian highland regiments that, at one time, had this style of ornamentation as part of their headgear (I've seen pictures of pipers in the 48th Highlanders from the 50's/60's wearing a balmoral with blackcock feathers). At some point seems to have been replaced by feather bonnets.

Correction, said balmoral, meant glengarry.
