The Lead-Off Bird (1954-62): This original Orioles bird rendering was perched proudly on Orioles' uniform caps for their first nine seasons. Note the genealogical resemblance to the Ornithologically Correct Bird of 1989-1997.
The Shoulder Patch Bird (1955-62): This bird was the official shoulder patch adornment of such early Orioles greats as Gus Triandos; Milt Pappas, Jim Gentile and Chuck Estrada: not to mention a couple of new kids' by the names of Brooks Robinson and Boog Powell.
Orange letter B (1963): Birdless In 1963, the bird flew the coop and was replaced by an orange letter B: the only season Orioles' caps were birdless.
The Chirping Bird (1964-65): The bird returns. So named for his chirping expression, this bird adorned the '64 and '65 uniform caps, and had plenty to chirp about: the '64 Orioles won 97 games and finished just two games out of first.
The Bird -- also known as the Cartoon Bird (1966-89): Brooks, Frank, Boog, Jim, Earl and even Cal... Virtually every Oriole great, and anyone who put on an Orioles uniform between 1966 and 1989 has donned a cap with this bird on it. The look of the caps changed through the years, but the bird remained the same.
The Ornithologically Correct Bird (1989-97): In 1989, with 35 seasons, 6 division titles and 3 World Championships under their belts, the Orioles put a new bird on their caps. In the age of political correctness, the Orioles chose a bird rendering that "Bird" fans and bird watchers could both appreciate.
The Lifelike Bird (1998-2008): An update of the Ornithologically Correct Bird of the previous 8 seasons, the Orioles found this bird a more lifelike interpretation of the actual live Oriole bird. For the 1999 season, the lifelike bird was updated slightly and given a more proud image. Although the changes in his appearance may seem slight, he is much more stately and majestic in his stance. This bird currently sits proudly on the caps and shoulders of the Orioles' uniforms.
The Traditional Bird (2008 - 2011): In 2008, along with the introduction of the new Baltimore road jersey, the O's redesigned the Oriole bird to better evoke the shape and feel of some of the team's historical logos. The bird was also simplified with the removal of all colors except the more traditional black, orange, white and grey.
The "New" Cartoon Bird (2012 - present): To celebrate the 20th Anniversary Season of Oriole Park at Camden Yards, the team introduced a slightly modernized cartoon bird on its home and road caps and batting helmets. The new bird borrows elements from the cartoon bird of the 60's and 70's, with refined details and also the team's O's alternate cap.
The Warm-Up Bird (1954): The bird is born. The Orioles' original mascot as he appeared in a rough sketch by his creator, the Sun's Jim Hartzell.
The Hartzell Bird (1954-64): All dressed up for the cover of the first Opening Day program, April 15, 1954.
The Decker Bird (1964-65): By 1964, thanks to winning records in three of their last four seasons, the Orioles looked more intimidating than ever. Thanks to local illustrator Hal Decker, so did the Oriole bird logo.
The Walsh Bird (1966): Right after designer Stan Walsh -- creator of such unforgettable icons as the Hamm's Bear and Snap, Crackle and Pop -- got the bird all dressed up, the Orioles gave him someplace to go. The 1966 World Series.
The Front Page Bird (1966-91): From June 30, 1966 until 1991, to discover their team's fate, Orioles fans simply had to glance at Jim Hartzell's cartoon on the Sun's front page. Here, for example, a victory over the Yankees.
The Peacock Bird (1967): After the Orioles' four game sweep of the Dodgers to win the 1966 World Championship, the '67 bird strutted his stuff by adding a cape and crown to his plumage.
The Cuckoo Bird (1968): After a disappointing 1967 season, this character, also known as the Psycho Bird, told us to "Wait Til This Year." As it turned out, he and the Orioles had to wait until the next year to face the Miracle Mets in the '69 World Series.
The 40th Anniversary Bird (1994): He's back! A perfect blend of past and present, the original bird teams up with the Oriole Park at Camden Yards logo to celebrate 40 fabulous seasons of baseball in Baltimore.
The Baby Bird (1997-Present): In 1997, the Orioles created a new "fun bird" which has played a variety of roles in the Orioles organization. The Baby Bird now is used exclusively with the Junior Orioles Dugout Club Bird and other youth-oriented programs.
