Have you tried single AF point? I’m not a BIF specialist as some other people here but I do a lot of birding and CDMazoff, one of our kingpins around here told me to stick with single AF point.

I have no experience with your tamron lens but BIF require fast lens.

I’m using the original 7D from 2009 and it’s doing a good job except for ISO noise at 1600 and over but for the rest, it works fine. I stick to the single AF point 99% of the time along with the AI servo function. Basically I created a custom function at 1/1600, f5.6, AI servo, and Auto ISO. In some occasions I will slow speed to 1/1000 and/or aperture at f5.6 or 6.3 (my lens combo is limited at f5.6) but I always stick to these values. I also have a second setup with automatic exposure compensation at 1/3 and it often helps.

I’m not sure I could follow them with a single point at the speeds and size of them! I can give it a try. My camera has no custom function buttons on the top or anything and not many buttons so it’s tough to set that stuff up.  Good advice though thank you
