Lyric discussion by NoLiesJustLove116 

I've read someone mention elsewhere that the line ''You're the yellow bird I've been waiting for'' in Poison Oak means his friend's brother dying was what led Conor to stop abusing alcohol and drugs. (i.e: that death was the ''yellow bird'' that alerted him to how much he was putting his life in danger, just like yellow birds used to alert ppl that mines are dangerous).

So, I think

And my friend comes after work When the features start to blur She says these bars are filled with things that kill By now you probably should have learned

Did you forget that yellow bird? How could you forget your yellow bird?

means his friend telling him ''How could you forget that people die from drinking the way you're doing? How could you forget your wake-up call?''
