A friend told me about the Marsh Wrens at Fern Ridge Wildlife Area, so I have been watching for them ever since. They love to hide in the cattail plants found in the wetlands, which are called bulrushes in England. "Cattail is a tall, reedlike marsh plant with strap like leaves and a dark brown, velvety cylindrical head of numerous tiny flowers. Also called reed mace, bulrush." (Bing) Of course, this makes them very difficult to photograph even when you catch sight of them. The tall leaves of the reeds make a perfect hiding place for this little bird. Interestingly, as stated in the information below, they tend to stay down in the reeds. That's why I had such a time getting a shot of one.

"The Marsh Wren is a small, plump, round-bodied wren with a short tail that it often holds up almost vertically above its back. It has a thin bill and short wings."

"Marsh Wrens cling to stems of wetland vegetation, often with each foot on a different stalk shimmying up and down and belting out series of gurgling, buzzy trills. They tend to stay down in the reeds, but males sometimes pop up to sing on taller stems especially early in the breeding season. Displaying males also fly weakly above the marsh, fluttering downwards and dropping straight back into the reeds. Adults often return to the same breeding territories year after year. Males arrive on the breeding grounds first and begin building several dome-shaped nests. When a female arrives, he cocks his tail and sings. He then escorts her around to his nests, bowing and holding up his tail. Once the female selects the nest they both aggressively defend the territory, but males don't stick with just one female; they frequently mate with others. Males and females also destroy the eggs and nestlings of other Marsh Wrens and nesting birds, perhaps in a fight over resources."
