With luck
About 10% of wildlife watchers report a Western Green Lizard sighting in Rome on a given day, based on 5 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 20%, and over a week to about 30%, if each day is a fresh chance.
April and June–August
In those months about 10% of wildlife watchers report a Western Green Lizard in Rome on a given day, against under 5% in May and September–March, the lowest months. Those are among Rome's driest months, with about 35 mm of rain a month against 110 mm in November.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Western Green Lizard 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 2 cities where we can rate Western Green Lizard sightings, Rome ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Milan (Italy, about 10%).
Same family: Lacertidae
The closest relatives of the Western Green Lizard that you can see in Rome (family Lacertidae, Wall Lizards) are Italian Wall Lizard (about 60%) and Common Wall Lizard (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Western Green Lizard is recorded against all the reptiles logged in Rome (5 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.
