The golden-bellied flycatcher (Myiodynastes hemichrysus) is a passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Colombia, Costa Rica, Ecuador, Panama, Peru, and Venezuela. The golden-bellied flycatcher has a complicated taxonomic history. It was originally described as Hypermitres hemichrysus. By the early 1900s it had been reassigned to genus Myiodynastes, which had been erected in 1847. A 1927 publication treated it as a subspecies of the golden-crowned flycatcher (M. chrysocephalus).
By at least 1979 it was again being treated as a full species. At that time it was considered monotypic. A 2016 publication detailed the vocal differences and similarities between the golden-bellied flycatcher and the three subspecies of the golden-crowned flycatcher. Based on that study, by 2020 BirdLife International's Handbook of the Birds of the World moved two subspecies from the golden-crowned to the golden-bellied. The Clements taxonomy followed suit in 2022 and the IOC and both subcommittees of the American Ornithological Society in 2023. The golden-bellied and golden-crowned flycatchers are sister species.

Rare
Under 5% of wildlife watchers report a Golden-bellied Flycatcher sighting in San José on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 299th most-seen of the 379 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Golden-bellied Flycatcher in San José on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Golden-bellied 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.
Among the best
Of the 3 cities where we can rate Golden-bellied Flycatcher sightings, San José ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Cali (Colombia, under 5%) and Medellín (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Golden-bellied Flycatcher is recorded against all the birds logged in San José (16 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.
