Rare
Under 5% of wildlife watchers report a Spot-billed Ground-Tyrant sighting in Arequipa on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 46th most-seen of the 61 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Spot-billed Ground-Tyrant in Arequipa on a given day, against under 5% in July to April, the lowest months. Those are among Arequipa's driest months, with almost no rain against 45 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Spot-billed Ground-Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Arequipa, in our data
Arequipa is the only city on Wallace's Line with enough records to rate Spot-billed Ground-Tyrant sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Spot-billed Ground-Tyrant is recorded against all the birds logged in Arequipa (58 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.
