The rusty-margined flycatcher (Myiozetetes cayanensis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Panama and every mainland South American country except Chile and Uruguay, though only as a vagrant to Argentina. It has also been recorded as a vagrant in Costa Rica.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the rusty-margined flycatcher in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le gobe-mouche de Cayenne and the Latin Muscicapa Cayanensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added the rusty-margined flycatcher among the 240 species that had been previously described by Brisson. Linnaeus included a brief description, used Brisson's Latin name as the binomial name Muscicapa cayanensis, and cited Brisson's work. This species is now placed in the genus Myiozetetes that was erected by the English zoologist... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rusty-margined Flycatcher sighting in Chagres National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 241st most-seen of the 372 birds 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.
January
In that month about 10% of wildlife watchers report a Rusty-margined Flycatcher in Chagres National Park on a given day, against under 5% in February to December, the lowest months. That is one of Chagres National Park's driest months, with about 55 mm of rain against 300 mm in July.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Rusty-margined 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.
18th of 25
Of the 25 parks where we can rate Rusty-margined Flycatcher sightings, Chagres National Park ranks 18th at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 40%), Parque Estadual Encontro das Águas (Brazil, about 40%) and Soberanía National Park (Panama, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Rusty-margined Flycatcher is recorded against all the birds logged in Chagres National Park (33 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.
