Wanna fly up in the sky
There’s something more I seek

I wanna feel the warmth of the
Morning sun across my beak

'Cause I’m a seagull, yeah, yeah
I got a beak, yeah, yeah

This verse, he talks about leaving the rock again. Well, the relationship, obviously. “Feeling the sun on his beak”, the beak is, obviously, a phallic symbol. It’s his penis.
