Rare
Under 5% of wildlife watchers report a Dark-billed Cuckoo sighting in Cordoba on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 176 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 Dark-billed Cuckoo in Cordoba on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dark-billed Cuckoo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 7 cities where we can rate Dark-billed Cuckoo sightings, Cordoba ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Buenos Aires (Argentina, under 5%), Santa Cruz de la Sierra (Bolivia, under 5%) and Asuncion (Paraguay, under 5%).
GBIF citizen-science records
It is estimated from how often the Dark-billed Cuckoo is recorded against all the birds logged in Cordoba (14 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.
