With luck
About 10% of wildlife watchers report a White-Tipped Black sighting in San Salvador on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 72 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April and November
In those months about 20% of wildlife watchers report a White-Tipped Black in San Salvador on a given day, against under 5% in January–February and July, the lowest months. Those are among San Salvador's driest months, with about 45 mm of rain a month against 280 mm in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-Tipped Black sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 14
Of the 14 cities where we can rate White-Tipped Black sightings, San Salvador ranks 3rd at about 10%. The best odds are in San José (Costa Rica, about 20%) and Bogota (Colombia, about 10%).
GBIF citizen-science records
It is estimated from how often the White-Tipped Black is recorded against all the insects logged in San Salvador (13 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.
