The Evolution of Sam the Eagle (1975-present)

Image	As seen in	Year	Notes
	The Muppet Show: Sex and Violence	1975	Sam makes his debut in The Muppet Show: Sex and Violence.
	Muppet Meeting Films	1975	Around the same time as Sex and Violence, Sam appears in two Muppet Meeting Films. This Sam has bushier eyebrows, longer hair, and a slight blue-green hue.
	The Muppet Show Season 1	1976	Although similar to the first puppet, Sam's hues are such that the foam material's natural coloring and texture is more evident. His jaw tends to modulate from side to side, and his beak in general is at its longest.
	The Muppet Show Season 1	1976 through 1977	A new Sam puppet premiered in episode 117, and another in episode 119. Sam's eyebrows have been trimmed and the fringe of hair/feathers combed down somewhat. The beak has been reshaped slightly, and wing feather coloration made brighter, though the face and body hues still clash.
	The Great Muppet Caper	1979 through 1981	As seen in later seasons of The Muppet Show and in The Great Muppet Caper, Sam's head has finally become a deeper blue, and the curve of the beak emphasized. The body feathers have also been re-dyed.
	Muppets from Space	1999	With coloration only slightly lightened from the last version (and fluctuating between the two in subsequent years), the top of Sam's skull has been rounded, and the eyebrows further trimmed, almost forming a Bert-like unibrow.
	It's a Very Merry Muppet Christmas Movie	2002	Sam undergoes a plot-oriented change, with a fuller head of hair, or feathers, the result of his use of Propecia.
