and if i was hiding the bird would be closer to me
"Birding" is indeed a bit like being lucky at hide and seek, and that's one problem: You can take an "ok" shot with your mighty expensive gear, and then the next guy with a Rebel kit lens happens to walk up right next to the bird, taking a better shot...

but if i didn't have 1/2000 he would be blurry.
... and that's the other problem: Even if you have a tracking camera (I wouldn't even bother with my 6d), "sitting duck" in lower light has an *entirely* different iso requirement than "in flight". With IS on and snapping a few frames, you can high iq shots w/o movement. When something starts moving at higher speed, you indeed need 1/1500 (horses) or at least 1/2000 (bif), and the iso value goes through the roof.
