The grey-and-gold warbler (Myiothlypis fraseri) is a species of bird in the family Parulidae, the New World warblers. It is found in Ecuador and Peru. The grey-and-gold warbler was formally described in 1884 with the binomial Basileuterus fraseri. The specific epithet fraseri honors Louis Fraser, who collected the first specimen. 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.
The grey-and-gold warbler is about 14 cm (5.5 in) long. Males weigh an average of 12 g (0.42 oz) and females average 12 g (0.42 oz). The sexes have the same plumage.

Their chin is white and the rest of their... Wikipedia →

With luck
About 10% of wildlife watchers report a Gray-and-gold Warbler sighting in Guayaquil on a given day, based on 80 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 167 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November and December
In those months about 20% of wildlife watchers report a Gray-and-gold Warbler in Guayaquil on a given day, against under 5% in January to May, the lowest months. Those are among Guayaquil's driest months, with about 15 mm of rain a month against 220 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 Guayaquil, in our data
Guayaquil is the only city 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 Guayaquil (80 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.
