What is the object above Chief Wahoo's head in some Indian logos?

The only object I know of above Chief Wahoo's head, in any Indians logo, is a feather attached to the back of his head.

The 1954 Cleveland Indians won the American League championship, only to fall to the New York Giants in the World Series. To indicate the championship, they employed an alternate logo featuring Wahoo looking up at a crown on his head in 1955 and sometimes beyond.

What's confusing is that Sportslogos.net indicated this logo was in use in 1953, prior to winning that particular title.
