Aha!! Someone mentioned my name in surprise [lol]

The info was taken from my web-site. I don't mind as it
was hardly mine in the first place.

**Owl, Brown (Tawny Owl, Wood Owl). - The small mottled brown hackles on the upper edged of this bird?s wing are used in some north country patterns. The blue for from the base of the plumage is also recommended by one writer for the dubbing of bodies. The larger wing feathers are used for winging large moths or night flies.

Brown Owl: Now very difficult to obtain but once commonly employed and very useful. Any reddish-brown marginal covert feathers may be substituted and I recommend French Partridge hackles colored with a Pantone pen.

Fogg's suggestion of French partridge wings is a very good one as they are very cheap over here, a very good
alternative to dyed hen. For tying a few flies, you don't need a whole dyed hen neck.
At 2BPounds a pair from Cookshill a real bargain.
