For stationary birds, I have no issues with the AF.

Does anyone have comments on use with 1.4x or 2x teleconverter, either the Sigma Apo or the Canon II or III? I am thinking of taking this lens on a rainforest tour, and the versatility would be increased. Scenario would be 2 APS-C cameras, 1 with Sigma, 1 with the 15-85mm for general landscape use.

I don't have the 180, but the Sigma 150mm macro (latest version) seems to work just fine with a Canon 1.4x III.

The Canon 1.4 III does not fit without an ET.  The Canon 2.0 III fits (without an ET), but so tightly that I have only used it twice.  I'll not do that again.  I inquired at KEH repair about them modifying the 2.0 to fit and they said there is a hard to get part and they really do not recommend it anyway.

I can't comment on the Sigma TC's.
