I'm talking about plain exposure. You get it in any mode, and it's applied BEFORE the picture is taken. - ev numbers means underexposing, + ev is overexposing.
https://digital-photography-school.com/ev-compensation-explained0 ev is what camera is determining to be proper exposure. It depends on various factors and you often have few options of determining how it works in menus. They're called metering modes.

If you're shooting in auto, shutter, or aperture priority modes, you'll have a dial or button, or maybe even only menu option, all depending on your camera, with which you'll be able to underexpose or overexpose your shot before it's taken. It's + or - number on the screen on most cameras. Fool with it and you'll soon learn what it does.
Specifically for bird shooting, I'm often underexposing when shooting birbs in flight, so I can get higher shutter speeds and lower isos, and I'll trust quality will be high enough to allow me to bring underexposed shots up in postprocessing. But it varies extremely from case to case. Shooting black birbs, or birbs with strong backlighting, I'll actually overexpose so I won't loose shadow details. Most of the time, it's just a matter of what feels best, or even what happens to be set in camera.
