Loggerhead Shrike (Lanius ludovicianus) lives in open grasslands across North America. It feeds on insects and vertebrates. Its conservation status is Near Threatened.
Fascinating facts about the Loggerhead Shrike
- Even insects as light as a thousandth of a gram become prey for this tiny predator, while it can also dispatch 25-gram mice. Its hooked beak snaps vertebrate necks, then the animal is driven onto a thorn or barbed wire where it is impaled and torn apart.
- A loggerhead shrike measures just 7.9-9.1 in (20-23 cm) long, yet its wings stretch 11.0-12.6 in (27.9-32.0 cm) across, roughly the span of a small school-bus window. Adults weigh on average 1.8 oz (50 g) with a healthy range of 1.6-2.1 oz (45-60 g). These compact dimensions give it the agility to hover on telephone wires 13 ft (4 m) high, scanning open fields for unsuspecting insects while staying light enough to launch rapid, lethal strikes.
- A pair lays 4 to 8 speckled eggs in a cup nest built 8-15 ft (2.4-4.6 m) above ground, then the female sits on them for about 16 days while the male brings food. Once hatched, the chicks fledge after roughly 19 days but remain dependent for another three to four weeks, learning the deadly impaling technique before they can hunt on their own. The longest-lived wild individual recorded lived 12 years and 6 months, showing that despite a high early-life mortality, survivors can persist for over a decade.
- During spring migration the loggerhead arrives in the Midwest between March 15 and March 25, then departs for winter around November 1-15. This narrow window reflects its reliance on open grasslands and abundant insects, which vanish as temperatures drop.
- The eastern subspecies is on the brink of disappearance in Canada, with fewer than 35 breeding pairs left, while the island-restricted San Clemente shrike once fell to just 5-10 individuals in the late 1980s.
