A species of bird watcher. Not as fanatical as a twitcher. A bird will find hours of entertainment sitting by a window or in his car watching the behaviour and interaction of various species of birds.
My father was a birder, he would sit for hours staring onto the garden watching the flocks of chaffinches that thronged to his feeding table.

A birder is a lad who laps up attention off the ladies and thinks of themselves as pretty much a big deal. Probably quite good looking, but more importantly, thinks that they're the fittest thing to ever walk the earth.

Birders will always have several girls on the go, and probably have different names for all of them. E.g 'wifey', 'baby girl' or 'boo' - this keeps all the women feeling special and thinking that they're the only 1

Anyone who kills a bird whether intentionally or otherwise. For example; a friend of mine hit a bird today.. and instead of calling her a "bird murderer" in the text that I was typing to her, I consolidated and threw "birderer" at her. I actually think it cheered her bird-killing self up a bit.
girl driving car: oh crap i think i just hit that bird
guy passenger: wow it's not moving, I think you killed it... YOU BIRDERER
