The moaning frog is named for its call, which sounds like a slow and drawn-out moan. This burrowing frog is native to southwestern Western Australia, where its calls can keep people up at night — it's recommended to gently flood the frog's burrow each night until the moaning male moves on.

The willie wagtail is aggressively territorial. It's known to harass much larger birds (including eagles), venomous snakes, and humans that wander too close to its nest. Before an assault, it flares its white "eyebrows", making it look especially enraged.
