Rare
Under 5% of wildlife watchers report a Mexican Whip-poor-will sighting in Mexico City on a given day, based on 43 verified sightings from GBIF citizen-science data. It is the 284th 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 Mexican Whip-poor-will in Mexico City on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Mexican Whip-poor-will sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Mexican Whip-poor-will sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mexican Whip-poor-will is recorded against all the birds logged in Mexico City (43 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.
