Dog barking at birds

Ok guys I know there are a few upland hunters on here and I need some advice.

I have a two year old GSP of whom I got when she was about a year and a half. She never had any hunting training, but had some basic obedience stuff taught to her and was already introduced to the e collar.

Anyway, I got her and started putting birds out for her (quail), she never barked at any of them when I put them out, but also has not pointed one yet. She points all kind of random things, squirrels, lizards, all kinds of crazy shite, and has even pointed a couple of doves.

I noticed over the past few times of bringing her to the camp that she barks at shite birds all the time when running through rice and hay fields and also squirrels (she has always barked at squirrels). My point is what do I need to do about this? I don't exactly want her running through the woods and fields and just barking at everything that she sees. Any advice would be greatly appreciated.
