A tomial tooth is not actually a tooth, but a sharp tooth-like projection located on the end of the bill
You would never guess that this bird is nicknamed the “butcherbird”. Looks can be deceiving. The loggerhead shrike is a small bird measuring between eight and nine inches long and weighing less than two ouches (similar to a robin). At full size, their wingspan is around a foot. They can be found year-round from Mexico to as far north as the Mason-Dixon line. Their breeding territory is farther north ranging from the North-Central United States to South-Central Canada.
This bird gets its name from the disproportionately large head to body ratio. The loggerhead shrike has what looks like a black mask over its eyes. This shrike (like other shrikes, kites, and raptors) has what is called a tomial tooth. A tomial tooth is not actually a tooth, but a sharp tooth-like projection located on the end of the bill. This is used to tear apart prey. Their highly evolved beak allows the loggerhead shrike to break the neck of a small vertebrate.
The list of prey this small bird consumes is wild! These shrikes eat insects, lizards, bats, arachnids, amphibians, small mammals, small birds, and apparently crabs. These small birds will perch above the ground, then swoop down to attack prey. Loggerhead shrikes do not have to fly to scout for food, they just scan and wait for the right time. Because of this, these birds are highly efficient hunters, managing their energy expenditure effectively.
The loggerhead shrike can take down animals larger than itself! How does it do that? The loggerhead shrike will impale its larger prey on thorns. Sometimes it will use the thorns to help hold the prey while it rips it apart. Alternately, the loggerhead shrike may leave the impaled prey in place and come back to eat it later.

Breeding occurs during the spring. The females will lay between four to eight eggs in their nest. The incubation period lasts around 16 days. Once the eggs hatch, both the male and female shrikes will feed their young. If any of the nestlings die, the adult loggerhead shrikes may eat them or feed them to the living siblings!
