Any good anagrams for stifftail?

The stiff-tailed ducks, the genus Oxyura, are part of the Oxyurini tribe of ducks. All have, as their name implies, long, stiff tail feathers, which are erected when the bird is resting. All have relatively large, swollen bills. These are freshwater diving ducks. Their legs are set far back, which makes them awkward on land, so they rarely leave the water. Their unusual displays involve drumming noises from inflatable throat sacs, head throwing, and erecting short crests. Plumage sequences are complicated, and aging difficult. Plumage is vital for survival because of this animals tendency to spend time in the water.
