The Pied-billed Grebe (*Podilymbus podiceps*) is a small, stocky diving bird found across much of North and South America, commonly inhabiting freshwater ponds, lakes, marshes, and slow-moving streams. It has a compact, rounded body with virtually no visible tail, brown overall plumage, and a short, thick, chicken-like bill — which in breeding season displays the distinctive black ring (or "pied" marking) that gives the species its name. It is a remarkably capable diver, able to slowly sink below the surface by compressing its feathers to expel air, almost like a submarine, rather than diving with a dramatic plunge. Its lobed toes, set far back on its body, make it an agile swimmer but quite awkward on land, so it rarely ventures out of the water. The Pied-billed Grebe is also known for its loud, whooping, cuckoo-like call that echoes across wetlands, often heard before the bird is ever seen, as it tends to hide among reeds and emergent vegetation when disturbed.
