Color varies clinally, though, and it is now commonly accepted that they comprise one species. There are also two species of harrier-hawks in Africa of the genus Polyboroides that, while they are morphologically and behaviorally similar, are not very closely related. They serve as a good example of convergent evolution.
Six subspecies are recognised: Crane hawks occur in tropical lowlands at the edge of forests and are almost always... Wikipedia →

Rare
Under 5% of wildlife watchers report a Crane Hawk sighting in Guayaquil on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 116th most-seen of the 167 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and December
In those months about 10% of wildlife watchers report a Crane Hawk in Guayaquil on a given day, against under 5% in January–April and June–November, the lowest months. Those are among Guayaquil's driest months, with about 30 mm of rain a month against 220 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Crane 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.

GBIF citizen-science records
It is estimated from how often the Crane Hawk is recorded against all the birds logged in Guayaquil (17 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.
