Get a longer lens!!!
Seriously. If you are serious about photographing wildlife you need either a longer lens or an f2.8 or faster 200 to 300mm lens.
If you try to make your 70-300, which will be f5.6 at the long end, work with a 2x teleconverter you will end up with a 600mm f11 lens. This will be getting quite dark to focus manually and your auto focus will have difficulty at the f11 light level.
