Limnornis curvirostris
In 3 days <5%
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. 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. 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... Wikipedia →

Rare
Under 5% of wildlife watchers report a Curve-billed Reedhaunter sighting in Buenos Aires on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 241st most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Curve-billed Reedhaunter in Buenos Aires on a given day, so our monthly data shows no clear season.
Only Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Curve-billed Reedhaunter sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Furnariidae
The closest relatives of the Curve-billed Reedhaunter that you can see in Buenos Aires (family Furnariidae, Ovenbirds and Woodcreepers) are Rufous Hornero (about 90%), Narrow-billed Woodcreeper (about 40%) and Sooty-fronted Spinetail (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Curve-billed Reedhaunter is recorded against all the birds logged in Buenos Aires (24 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
