This works great.  I've used the 14256 with the 60, 280 (f/4.8), 400 and
560 (f/6.8) and if you can get that close to the animal the backgrounds are
obliterated.  There is also a 60mm extension tube made for the 400 and 560
f/6.8 Telyts that fits between the lens head and mount tube that will give
you twice the extension of the 14256; with this extension tube and the 400
I've made full-frame photos of hummingbirds at 6' (2 meters).
