The Cosseboom

The Cosseboom was created by John C. Cosseboom around 1923, for use on the Margaree River in Nova Scotia Canada. 

The Cosseboom was originally tied with an olive green body, silver tinsel ribbing, grey squirrel tail wing, and a lemon-yellow hackle tied as a collar after the wing was applied, with a red head. Other body and hackle color combinations have evolved, but all retain the grey squirrel tail wing. The Cosseboom remains a very popular and effective Atlantic salmon fly and is used worldwide.
