Nailed It!
Check out this nest! Jack Perreault found this House Wren nest in one of his nest boxes as he was cleaning them out this fall. House Wrens typically make nests out of small twigs, but Jack says he counted 102 nails of varying types incorporated into these nesting materials. A typical two-inch roofing nail weighs about three grams, which is about a quarter of the weight of an adult House Wren—an amazing feat indeed!
