Rare
Under 5% of wildlife watchers report a Slaty-backed Nightingale-Thrush sighting in San José on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 346th most-seen of the 379 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 Slaty-backed Nightingale-Thrush in San José on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Slaty-backed Nightingale-Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only San José, in our data

GBIF citizen-science records
It is estimated from how often the Slaty-backed Nightingale-Thrush is recorded against all the birds logged in San José (6 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.
