Shrikes, medium-sized carnivorous birds, impale prey on sharp objects. They defend their territories, form monogamous pairs, and males court females through feeding and ritualized dances. They build nests from twigs and grasses, and some species engage in cooperative breeding.
Medium-sized shrikes can have brown, grey, or black-and-white feathers. The majority of species range in size from 16 cm (6.3 in) to 25 cm (9.8 in); however, the genus Corvinella can grow up to 50 cm (20 in) in length due to its incredibly long tail-feathers. Their calls are loud, and their hooked beaks, resembling those of a predatory bird, indicate that they are carnivorous. The practice of male shrikes capturing insects and small vertebrates and impaling them on thorns, branches, barbed-wire fence spikes, or any other sharp object is well-known. In order to allow the shrike to revisit the uneaten sections later, these stores act as a cache.
Patient Focus Perched on a thin branch, the shrike waits.
However, researchers believe that males prominently impale prey on thorny flora to show potential mates their fitness and the quality of their territory. When the breeding season begins, impaling behavior rises. Although observers have seen female shrikes impale prey, they mainly help dismember their victims. It’s also possible that this behavior is a secondary adaptation to consuming the poisonous lubber grasshopper. Before consuming the grasshopper, the bird waits one to two days for the chemicals inside to break down.
Floral Perch On a beautiful flower, the shrike pauses.
Shrikes protect their territories from other pairs because they are territorial. In migratory species, they develop a smaller feeding zone during migration and in the wintering grounds, while they protect a breeding region in the breeding grounds. When multiple shrike species coexist, territorial rivalry can be fierce. Shrikes frequently choose open perch locations, where they prominently stand upright.

They use these sites to alert competitors of their presence and to keep an eye out for prey. Shrikes are monogamous breeders. cooperative breeding, in which young birds assist their parents in raising their offspring. Males use well-stocked caches, which may contain inedible but vibrantly colored objects, to entice females to their territory. The male feeds the female and engages in a ritualized dance during courtship that includes motions that resemble skewering prey on thorns. Shrikes use twigs, grasses, bushes, and the lower branches of trees to construct their basic, cup-shaped nests.
