Sam the Eagle is a supporting character from that Jim Henson franchise about those weirdoes, the Muppets. He is a noble, blue-feathered, red-blooded American Eagle, one who is known for his extreme patriotism and strict, disciplinary attitude...much different from the low-class behaviour of the rest of the Muppets.
Frank Oz was the first Muppeteer to perform Sam. Perhaps it's simply this particular clip of Frank's earlier forays with Sam, but I feel like his voice was also in "prototype" mode. It was never quite refined.
In the early 2000s, Kevin Clash took over the role for a small handful of titles. This is not one of Kevin's better roles, I'm afraid to say.
Eric Jacobson was next on the list to portray Sam in a large number of titles. Eric is my #1 choice here, as I feel he took Frank's foundation of the character but improved upon it and made it his own.
In the series of shorts called "From The Balcony", puppeteer Drew Massey got his shot to soar as Sam. Unfortunately, while Drew's voice is passable, it sounds a bit forced, like he's straining to maintain it.
