I would strongly recommend that you get the D3200.
For purposes of photographing birds, you will often NOT be able to get as close as you want. The larger number of pixels on the D3200 sensor will allow you to crop way down and still get a good image.
Also for birds you need really fast shutter speeds. Under ideal conditions you can get those, but with less than great light you will need to turn up the ISO to keep the shutter speed up. The D3200 has excellent high ISO performance.
As others said, the 18-55 mm kit lens is a great lens for general and landscape photography. The next lens I bought was the 55-300 and it is a good next step. It will allow you to zoom in on more distant landscape features that you can't get otherwise, and is also good for bird photography if you can get close enough. It's also nice for portraits at about 80-100 mm.
If you find that the 55-300 lens is not enough for your purposes, the Sigma 150-500 is a highly regarded birding lens at a moderate cost.
But my advice is to start with the basic lens and see where you are limited by it, then add as you see what will fit your photography style.
