The pugnacious Marsh Wren is appropriately named, clinging to wetland vegetation, tail cocked and legs splayed, often with each foot wrapped around a different stalk. This rusty-brown wren has black-and-white streaks down its back and a white eyebrow. It sings a rapid-fire gurgling, trilling, and buzzy song from the depths of the marsh where its secretive life unfolds. Under the cover of reeds, males build multiple nests and breed with more than one female. They also destroy eggs and nestlings of other Marsh Wrens and marsh-nesting birds.
