Princeton ecologist Henry Horn was strolling past Princeton Stadium this summer when he noticed something interesting: An adult mockingbird was perched on the head one of the stainless steel tigers at the stadium’s entrance. Upon further observation, Henry discovered that the resourceful mockingbird had chosen the inside of the tiger’s mouth as a well-protected spot to raise its chicks. Fact: Princeton University’s most virtuosic mockingbird can sing the songs of 17 other bird species.
