Ok, after looking at some more numbers, and again this is only a WAG with really only 2 useable data points to go by. One can only go on the assumption that from the point of signal loss until restoration at that last data point for ony 100ms., that the bird continued on the same path, at the same speed and at the same rate of descent from the point of signal loss. Over the distance from signal loss to restoration, the bird only descended approximately 2 feet between those two points. So using that as part of the WAG and the speed indicated of 16ft/sec, this map shows where the bird "should" be within the yellow circle, giving GPS accuarcy and the previous assumptions. Being that it was at 67ft at the last data point ( give or take for Barometer error), I highly suspect it hit something in this area, that is of coarse if all assumptions are accurate. If it remained at that altitude or continued to descend, there is no way it would clear those trees, and possibly that other house in the yellow circle. The red line is just a 300 ft marker for reference. If you do not locate the bird in this area, then either as you mentioned, someone picked it up, or you have a flyway to who knows where. Also, you may want to re-post again with a different thread, and ask for Data Analysis and have another take a look just to double check. If you do, post the flight log along with it. And no problem helping out if I can.
