By 2007 taxonomic systems had begun to resurrect genus Myiothlypis, which had been erected in 1850, for the grey-and-gold warbler and many other species.

With luck
About 10% of wildlife watchers report a Gray-and-gold Warbler sighting in Machalilla National Park on a given day, based on 101 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Gray-and-gold Warbler in Machalilla National Park on a given day, against under 5% in April and August, the lowest months. That is one of Machalilla National Park's driest months, with about 25 mm of rain against 140 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray-and-gold Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Gray-and-gold Warbler sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gray-and-gold Warbler is recorded against all the birds logged in Machalilla National Park (101 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.
