(In the mid-20th century some previous authors had treated it as a species.) What is now the cryptic forest falcon (M. mintoni) was a population of the lined forest falcon until 2002 when vocal studies and specimen analyses determined it was a separate species. The plumbeous forest falcon (M. plumbeus) has sometimes been considered a subspecies of the lined forest falcon.
The lined forest falcon is monotypic. The lined forest falcon is 33 to 38 cm (13 to 15 in) long and weighs 170 to 262 g (6.0 to 9.2 oz). It has pale gray upperparts.

Likely
About 40% of wildlife watchers report a Lined Forest Falcon sighting in Brownsberg Nature Park on a given day, based on 103 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 60% of wildlife watchers report a Lined Forest Falcon in Brownsberg Nature Park on a given day, against about 30% in February–April, August and October, the lowest months. May to July have too few records to rate.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Lined Forest Falcon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Lined Forest Falcon sightings, Brownsberg Nature Park has the highest daily chance: about 40%. Next come Tambopata National Reserve (Peru, under 5%) and Yasuní National Park (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Lined Forest Falcon is recorded against all the birds logged in Brownsberg Nature Park (103 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.
