Rare
Under 5% of wildlife watchers report a Silvery Tanager sighting in Podocarpus National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 446 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July, September and December–January
In those months about 10% of wildlife watchers report a Silvery Tanager in Podocarpus National Park on a given day, against under 5% in February–June, August and October–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Silvery Tanager sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Podocarpus National Park, in our data
Podocarpus National Park is the only park on Wallace's Line with enough records to rate Silvery Tanager sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Silvery Tanager is recorded against all the birds logged in Podocarpus National Park (50 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.
