The white-necked hawk (Buteogallus lacernulatus) is a Vulnerable species of bird of prey in the subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is endemic to Brazil. The white-necked hawk was for a time placed in genus Leucopternis but molecular studies placed it in Buteogallus. A 2009 paper proposed the new monotypic genus Amadonastur for it but this treatment has not been accepted by worldwide taxonomic systems. The white-necked hawk is monotypic.
The white-necked hawk is 43 to 48 cm (17 to 19 in) long with a 91 to 101 cm (36 to 40 in) wingspan. Males and females have the same plumage, though females are about 4% larger than males. Adults have a white head and underparts and black upperparts. Their tail is black with a wide white band in the middle. Their eye is brown or pale yellow and their legs and feed yellow. Immatures are similar to adults but with dark streaks on their crown and neck, brown tips on some upperparts feathers, and white barring on the black base of their tail.
The white-necked hawk is found discontinuously in southeastern Brazil from Paraíba south to Paraná state... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-necked Hawk sighting in Rio de Janeiro on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 278 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 White-necked Hawk in Rio de Janeiro on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-necked Hawk sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate White-necked Hawk sightings, Rio de Janeiro ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Santos (Brazil, under 5%).

GBIF citizen-science records
It is estimated from how often the White-necked Hawk is recorded against all the birds logged in Rio de Janeiro (16 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.
