As I understand it, shrike larders usually involve thorns or a barbed
wire fence. I don't know if they would just drape a prey item over
vegetation. The Birds of North America account, by Reuven Yosef,
says that they impale their prey because they don't have talons like
raptors. Impaling is also part of caching.
