Rare
Under 5% of wildlife watchers report a Silvery Grebe sighting in Buenos Aires on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 272nd 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 Silvery Grebe in Buenos Aires 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 Silvery Grebe sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Silvery Grebe sightings, Buenos Aires ranks 3rd at under 5%. The best odds are in Cochabamba (Bolivia, about 20%) and Lima (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Silvery Grebe is recorded against all the birds logged in Buenos Aires (5 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.
