The alouette bird, namesake of the football team, is also known as the horned lark. That old Alouette logo was intended to be a caricature of the profile of an alouette bird. It was also 1970 when it debuted so art form of the day may have come into play. Groovy baby.
The new logo depicts an alouette in flight. It also takes the shape of the letter M. I suppose what makes it different is instead of a small logo on each side of the helmet they put one large logo on the top of the helmet with the wings sweeping down the sides.
You're as old as you've ever been and as young as you're ever going to be.
