Common Fiscal using man-made object during feeding.
de Swardt (2016) reported on a Common Fiscal Lanuis collaris impaling its prey on thorny objects such as Acacia thorns or on the barbs of barbed wire fences. It was always speculated that the shrikes used the thorns of trees or wires to have a better hold on the food item during feeding (see references in de Swardt 2016; Dean 2005).
