loggerhead shrike! Thank you animal planet! :)

Tarantula hawk?

Shrike in the US, Butcherbird in Australia.

Since you're quail hunting, I assume it was in the South, therefore I agree with DSMBirddog - it's a loggerhead shrike. If you were farther north, it could have been a northern shrike. They'll impale not only grasshoppers on thorns and barbed wire, but even small birds, mammals, snakes and amphibians if they can get a hold of them...

If it is indeed a Shrike (either Northern or Loggerhead, depending on location), shouldn't the title be: 'What Bird Predator Turns Prey into Taxidermy?'

As just about everybody above me has said, it's a shrike. This is common behavior for them, and most birders refer to this as the Shrikes "meat rack." In addition to barbed wire, they will also use large thorns (such as hawthorns) for this purpose.

shrikey!look at the size of that hopper!
