Possible
About 30% of wildlife watchers report a Gray Silky-flycatcher sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 64 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 103 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and December
In those months about 40% of wildlife watchers report a Gray Silky-flycatcher in Reserva de la Biosfera Mariposa Monarca on a given day, against about 20% in February and March, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 55 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray Silky-flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Gray Silky-flycatcher is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (64 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.
