Rare
Under 5% of wildlife watchers report a Russet Nightingale-Thrush sighting in Mexico City on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 266th most-seen of the 332 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 Russet Nightingale-Thrush in Mexico City on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Russet 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 Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Russet Nightingale-Thrush sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Russet Nightingale-Thrush is recorded against all the birds logged in Mexico City (41 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.
