“ The next species is the marsh-harrier (Circus æruginosus) , once abundant throughout Great Britain and Ireland, now, unhappily, extinct as a British species. This harrier, which was also called the moor-buzzard, is a graceful, handsome bird: the head creamy white; upper parts brown; beneath, buff, streaked with brown and chestnut; part of the wing and the tail silvery grey. In its buoyant flight and preying and nesting habits it resembles the hen harrier, but frequents fens and marshes instead of moors and uplands. ”
