Taking photos at night

I'm don't think I'm doing nocturnal photography right. I have a Canon EoS 700D with a 100-400mm lens. If I try photographing in autofocus the camera lets out a few preliminary flashes and then fails to focus, so doesn't take a picture. If I try to use manual focus I can't see anything through the viewfinder to focus. So I just set the focus by estimating the distance the bird is away and setting this on the dial on the lens. Then I take a photo looking through the viewfinder, observe what is in the field of view when the flash goes off, and then adjust the direction of the lens with more photos until the poor bird is actually in the field of view.

I didn't do as badly as you might think like this in the Dominican Republic the other day but surely it can't be right. Is there a limit to the distance that my camera can focus at with a flash, or is there something wrong with it?

Do you have a better beamer or something similar to "zoom" your flash output?

Otherwise, the energy reaching the target may be too little
