Gmelin based his description on the Tamatias noirs et blancs or Barbu à gros bec, de Cayenne that had been described and illustrated in 1780 by the French polymath the Comte de Buffon.

The Guianan puffbird is now placed in the genus Notharchus that was introduced in 1863 by the German ornithologists Jean Cabanis and Ferdinand Heine. The generic name combines the Ancient Greek nōthēs meaning "sluggish" and arkhos meaning "leader" or "chief". The specific epithet macrorhynchos is from... Wikipedia →

With luck
About 10% of wildlife watchers report a Guianan Puffbird sighting in Brownsberg Nature Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 142nd most-seen of the 221 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August–October and December–February
In those months about 10% of wildlife watchers report a Guianan Puffbird in Brownsberg Nature Park on a given day, against under 5% in March–April and November, the lowest months. May to July have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Guianan Puffbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Guianan Puffbird sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Guianan Puffbird is recorded against all the birds logged in Brownsberg Nature Park (22 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.
