My Sigma APO 400

The Sigma APO is cheap, I got mine a short while ago for 300 bucks. It's a decent performer. In high contrast scenes (=white birds) it suffers from some PF and significant haloing of the whites. It's sharp though, and some careful post-processing will give you goodresults. It works well with the Sigma TCs (at least the 2x which i have, so the 1.4x should be better). Mine is just the APO version, with 72mm filter thread. Reportedly, the AF apo tele macro is quite a bit better. But i couldn't get my hands on one...   On my APO, the MF ring is very light, which makes hand-holding even easier. It's also very sharp wide open, and only gets a little bit sharper stopped down. PF goes away at f/11. Here are some of my threads.

Having said all that, i think the DA* 300 is a better choice if you can spring for it. Ron will tell you what TC to use with it, if he hasn't already. It will focus much closer too, the APO 400 has an MFD of 4 meters. But can you get closer to the birds?

Also consider the Bigma 50-500.

At the very least, the APO will let you know if you want to spend the bucks for a better (=1300$) or much better (>5000$) lens... You can always sell it again at negligible cost.
