Schistocerca nitens is a species of grasshopper known by several names, including vagrant grasshopper and gray bird grasshopper.

Rare
Under 5% of wildlife watchers report a Gray Bird Grasshopper sighting in San Francisco on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 180th most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gray Bird Grasshopper in San Francisco on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Gray Bird Grasshopper sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 16
Of the 16 cities where we can rate Gray Bird Grasshopper sightings, San Francisco ranks 16th at under 5%. The best odds are in Los Angeles (United States, about 30%), Mesa (United States, about 20%) and San Diego (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Gray Bird Grasshopper is recorded against all the insects logged in San Francisco (70 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.
