Shrikes are known to impale prey on thorns or sharp broken branches. I have seen the Brown Shrike Lanius cristatus do this occasionally. On 21 December 2023 at the Malim Nawar Wetlands, Perak, Malaysia, I was able to observe the activity at close range, using the car as hide. The adult female I observed had a piece of an animal prey in the beak but it was too large to manage. It proceeded to impale the item on the sharp point of a broken branch in dead bush (see Plate 1).
It took three attempts for the bird to succeed. It then was able to eat the prey piecemeal (see Plate 2).
Good documentation of similar behaviour by Steven Cheong can be found in the link.
