It is found in the western and southern part of South America where it inhabits lakes and other types of open wetlands. There are two subspecies, which by some recent authorities are considered separate species.

Possible
About 20% of wildlife watchers report a Silvery Grebe sighting in Cochabamba on a given day, based on 75 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Silvery Grebe in Cochabamba on a given day, against about 10% in February–March, June and December, the lowest months. That is one of Cochabamba's driest months, with about 10 mm of rain against 100 mm in January.
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.
Yes
Of the 3 cities where we can rate Silvery Grebe sightings, Cochabamba has the highest daily chance: about 20%. Next come Lima (Peru, under 5%) and Buenos Aires (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Silvery Grebe is recorded against all the birds logged in Cochabamba (75 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.
