You mentioned calibrating the compass before hand. But the flight log does not show it taking place prior to flight. It shows you use Auto Flight. Do you use the Liftoff and Land function on the screen?
On the last 2 seconds of data the nose of the aircraft gets pulled or forced up to +20 degrees. The nose of the a/c went from east, to southeast, to northeast.The side of the a/c(aircraft) was tilted actually pretty far down to compensate for strong wind prior to the bird, and when the bird attacked, it took it down a little further and then raised it to almost level status before releasing the a/c. And finally, the bird actually lifted the a/c up 5ft higher in altitude before releasing.
I checked over 100 different forms of data stats available to me, and everything else checked out to be ok. The only thing I have a limited amount of data for is 100% of the R/C. I can see the activity of the stick movement, flight mode switch, and the RTH button. There was no what I call red flag warnings. Nothing pointing to the compass. Nothing pointing to bad gps signal.
Prior to spending time looking at the data I had doubts concerning the battery. But I did not see any red flags in battery data.
I hope this info helps.
