Possible
About 20% of wildlife watchers report a Blood Snake sighting in Managua on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 10 reptiles 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.
June
In that month about 40% of wildlife watchers report a Blood Snake in Managua on a given day, against under 5% in April–May, July–August and November–January, the lowest months. That is one of Managua's wettest months, with about 210 mm of rain against almost none in January.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Blood Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Blood Snake sightings, Managua ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Tegucigalpa (Honduras, about 20%).
Same family: Colubridae
The closest relatives of the Blood Snake that you can see in Managua (family Colubridae, Colubrid Snakes) are Black-banded Cat-eyed Snake (about 40%) and Hallowell's Centipede Snake (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blood Snake is recorded against all the reptiles logged in Managua (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.
