Feather in your bonnet

[theborderer]

I'm well aquainted with hackles which are a regimental form often denoting battle honours but I've never seen backcock feathers used in a military context.

So what IS the deal with these blackcock feathers?

The Blackcock feather is part of the No 1 Dress for Scottish Regiments and is worn only with the No 1 Dress Jacket, as opposed to the coloured hackles which identify the various Battalions of the Royal Regiment of Scotland. No 1 Dress shown in Photo.
