Oh yeah, see, they weren't originally in the game, but were introduced one by one in a series of events, which is why when those events started repeating we've known the order the next ones are going to appear in (but not necessarily events in between). The 5-star birds that are available all the time are:
Red: Geraldine & Claude
Yellow: Cyril & Billy the Blitz
Black: Byron & Dutch
White: Annie & Steve
Blue: Thrash & Murphy
Compare that to the list of Event Specific 5-star birds:
Red: Red, Terrence, Angry Santa, Fire Rooster, Ricky "Red Menace" Redtzky, Elite Ricky
Yellow: Chuck, Cold Turkey, Team Star Quarterback(s)
Black: Bomb, Black Metal Byron, Eddie the Bird, Dr. Probotnik, Kowalski the Elf
White: Matilda, Captain Freedom, "Fringy, Harbinger of Doom"
Blue: Heavy Metal Annie, The Angromedon, Grandfather Frost
Saving up your tickets to use when events are running is not just the most effective way to use them, but also the only time when most of the birds you'd want to hatch are even available at all.
