The French or Red-Legged Partridge is a dapper bird with some nice feathers. Aside from those very stylish breast feathers there are other nice ones in soft olive, brown and grey, as well as interesting neck feathers.
These two flies are tied with French Partridge feathers. The first is a French Partridge Mayfly, ostensibly a dry but to me more of a damp fly. From the small history I could find, it seems it's an old UK pattern. It looks to be a popular Irish lough fly, the Irish seem to be into these big damp type flies. I can't blame them, it's a great looking fly.
The second fly is one I made up in a palmered wet style and uses some of the feathers from other parts of the bird.
