With luck
About 10% of wildlife watchers report an Ash-browed Spinetail sighting in Podocarpus National Park on a given day, based on 223 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 446 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report an Ash-browed Spinetail in Podocarpus National Park on a given day, against about 10% in March and May–October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ash-browed Spinetail 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 Ash-browed Spinetail sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ash-browed Spinetail is recorded against all the birds logged in Podocarpus National Park (223 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.
