A picture of a black, gray and white bird appears.

A caption reads "This is the loggerhead strike. Also known as the butcher bird. So called because it impales its prey."

A picture shows an impaled bug.

The caption changes to "Which it does to compensate for its weak feet. The shrike then uses its hooked beak to tear up its food. Shrikes mostly eat grasshoppers. But they’ve been known to devour small mammals and birds, too. The loggerhead shrikes is one of Ontario’s at-risk species. No one knows where these birds go in winter. And many don’t come back. Of tracked shrikes, only 5 percent return with usable data. This makes it difficult to determine what’s harming the species. In 2015, there were just 11 breeding pairs left in the province. The population increased this year to 23 breeding pairs. To the chagrin of bugs everywhere."
