Hi talpogHi there Bezz
What's OIL CAN?
yea, you've got the place where it is correct. It's called an oil gland and the birds spread it on their feathers when they preen.Hi talpog
It is situated underneath the top coverflights at the base of the tail , where the tailfeathers are linked to the body of the bird.
I realy dont know how to describe it better as English isnt my Mother Tonque !, sorry, maybe someone else could assist?
