Curve-billed Reedhaunter

The curve-billed reedhaunter (Limnornis curvirostris) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Uruguay. == Taxonomy and systematics == The curve-billed reedhaunter and the superficially similar straight-billed reedhaunter (Limnoctites rectirostris) were long thought to be closely related; some authors merged Limnoctites into Limnornis. Genetic studies in the early 2000s refuted this approach by finding that the two species of genus Limnoctites were instead closely related to the spinetails of genus Cranioleuca. The curve-billed reedhaunter is instead most closely related to the wren-like rushbird (Phleocryptes melanops). The curve-billed reedhaunter is the only member of its genus and has no subspecies. == Description == The curve-billed reedhaunter is 15 to 17 cm (5.9 to 6.7 in) long and weighs 27 to 30 g (0.95 to 1.1 oz). It is a small furnariid whose plumage closely resembles that of some Old World reed warblers of genus Acrocephalus. It has a long and quite decurved bill. The sexes' plumages are alike. Adults have a whitish supercilium, an ill-defined dark brown band behind the eye, lighter brown ear coverts with some thin whitish streaks, and a whitish malar area. Their crown, nape…
