Rare
Under 5% of wildlife watchers report a Fasciated Wren sighting in Podocarpus National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 330th most-seen of the 446 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Fasciated Wren in Podocarpus National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Fasciated Wren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Fasciated Wren sightings, Podocarpus National Park ranks 2nd at under 5%. The best odds are in Machalilla National Park (Ecuador, about 20%).
GBIF citizen-science records
It is estimated from how often the Fasciated Wren is recorded against all the birds logged in Podocarpus National Park (20 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.
