Rare
Under 5% of wildlife watchers report a Mexican Forktail sighting in Saguaro National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 248th most-seen of the 354 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.
April
In that month about 10% of wildlife watchers report a Mexican Forktail in Saguaro National Park on a given day, against under 5% in May to March, the lowest months. That is one of Saguaro National Park's driest months, with about 5 mm of rain against 55 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Mexican Forktail 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 Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Mexican Forktail sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mexican Forktail is recorded against all the insects logged in Saguaro National Park (7 verified sightings from 2019 to 2026), 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.
