Pheasant on the Move

This male ring-necked pheasant was covering a lot of ground, obviously trying to locate some hens.  He would periodically cackle and I saw him once jump, flap, and cackle simultaneously like a barnyard rooster.  Unfortunately I was unable to capture that.  I liked his breeding colors, the full-blown wattle, and the late afternoon light.  I used a rented Nikon 2x teleconverter that day to see how suitable it would be with my 300 f4 lens and d800e.  Turns out it was very good in very good light on slow moving or large birds, but not so good on birds in flight (it hunted almost endlessly) or in low light.  D800e, 300f4, 2xtc, 1/500, F14, ISO 1000. 

I was impressed with how sharp this came out with the TC.  Not a terribly exciting composition, but I would be interested in your feedback nonetheless.
