Julius Caesar. Jesus Christ. Han Solo. All the subjects of famous betrayals. You know who else has been betrayed? These birds! Behold their tales of woe, dear reader, and take heed.
Northern Mockingbird's right hand man coveted his leadership position at Chemco, thinking he was the better bird for the job. He shoved Northern Mockingbird into a big open vat of chemicals at their evil chemical factory, which you think wouldn't work great because birds can fly. However, Northern Mockingbird was holding two doughnuts (one in each wing), and therefor was unable to get those wings moving in time. He was left for dead, but actually the chemicals gave him super powers, so he'll probably get revenge at some point.
Black Phoebe was not at fault for his downfall. He was pushed into a position of fame and prominence early in his life by his parents, who both had dreams of success that they hadn't achieved. After some early successful turns in commercials and TV shows, he got a major role in a movie that became a true genre classic. Black Phoebe missed a lot of school and normal social engagements to do this. He got exposed to some pretty messed up stuff early too, making it hard for him to transition into normal adulthood. His parents ended up embezzling all of the money he earned as an actor. He went through a rough patch, but seems to be getting some promising roles in indies now, and he's cleaned up his act.
California Scrub Jay was supposed to be a voice of his generation. His fiery speeches were compelling and convincing. He had a way of communicating that cut through typical political lines, speaking clearly both to the common man, and to the more idealistic types. Unfortunately, he kept getting caught sending inappropriate pictures, and in the mail, which made it even weirder. He survived a few scandals, but eventually retreated from the public eye. Years later, seeing what people are now willing to accept from their political leaders, he wonders why things turned out this way for him. In the end, he betrayed himself by believing that he could not fall in this way.
Anna's Hummingbird was talked into an adjustable rate mortgage when he didn't really have a stable enough income to cover it. Sure enough, times didn't stay green forever, and the house was repossessed, and financially he's never really recovered. The messed up part is that the shady realtor was his mother. Did she sabotage Anna's Hummingbird on purpose? Or was it a sub-conscious lashing-out as a result of their constant disagreements about the lifestyle choices he made? Either way, she knew about the risks and convinced him to go into it anyway. Anna's Hummingbird's credit score is still really bad. What a messed up thing to do.
