Not a very good shot (mega crop and face obscured) but a fun one.
Trying to get a warbler, kingbird, or flycatcher with an insect still in its mouth is tough. But when they catch large prey, they beat it to death before eating it so there's a slight chance to get a shot off.
Watching them dealing with a long caterpillar is very entertaining. This flycatcher with a hornet (wings still moving) was a lucky shot.
