Airforce wings

[SteveF]

Just have to point out that those members of the RCAF that were stationed in Canada during WW2 wore the same style shoulder badges as those shown with the dark background and only wore the "Canada" title while serving overseas. That being said, the construction of the top two badges being shown does not seem to match those on RCAF tunics that I have / have seen, but the bottom one does indeed look very similar to those on one of my tunics.
As for whether or not the birds are eagles or albatrosses... according to the current Canadian airforce the birds are, and have always been, eagles. There are some interesting theories on how the albatross got involved but from day one the bird was intended to represent an eagle (rather poorly done IMO). For some reason even though it is officially an eagle there are still people arguing that it is an albatross. Not sure why that is.
