The roadside hawk (Rupornis magnirostris) is a relatively small bird of prey found in the Americas. This vocal species is often the most common raptor in its range. It has many subspecies and is now usually placed in the monotypic genus Rupornis instead of Buteo.
The roadside hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the eagles, hawks and relatives in the genus Falco and coined the binomial name Falco magnirostris. Gmelin based his description on the "Épervier à gros bec de Cayenne" that had been described and illustrated in 1770 by the French polymath Comte de Buffon in his multi-volume Histoire Naturelle des Oiseaux. The roadside hawk is now the only species placed in the genus Rupornis that was introduced in 1844 by the German naturalist Johann Jakob Kaup. The genus name combines the Ancient Greek rhupos meaning "dirt" or "filth" with ornis meaning "bird". The specific epithet magnirostris combines the Latin magnus meaning "great" with -rostris meaning "billed".

Rare
Under 5% of wildlife watchers report a Roadside Hawk sighting in Cusuco National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 149th most-seen of the 250 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, May–June, October and December
In those months about 10% of wildlife watchers report a Roadside Hawk in Cusuco National Park on a given day, against under 5% in January, March–April, July–September and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Roadside 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.
57th of 77
Of the 77 parks where we can rate Roadside Hawk sightings, Cusuco National Park ranks 57th at under 5%. The best odds are in Parque Estadual Encontro das Águas (Brazil, about 70%), El Palmar National Park (Argentina, about 60%) and El Impenetrable National Park (Argentina, about 60%). All parks ranked.
Same family: Accipitridae
The closest relatives of the Roadside Hawk that you can see in Cusuco National Park (family Accipitridae, Hawks, Eagles, and Kites) are Gray-lined Hawk (about 20%), American Swallow-tailed Kite (about 10%) and Short-tailed Hawk (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Roadside Hawk is recorded against all the birds logged in Cusuco National Park (28 verified sightings from 2019 to 2026), 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.
