The yellow-rumped warbler (Setophaga coronata) is a North American bird species that can be commonly observed all across the continent. Its extensive range connects both the Pacific and Atlantic coasts of the U.S. as well as Canada and Central America, with the population concentrated in the continent's northern reaches during the breeding season and migrating southwards to southern North and Central America in the winter. It generally prefers coniferous forests or mixed coniferous-deciduous forests as its breeding habitat, while during the winter it can be found inhabiting more open areas such as shrublands that offer food resources. The yellow-rumped warbler is primarily insectivorous, though the species eats fruit such as juniper berries, especially in winter.
The species combines four closely related forms: the eastern myrtle warbler (spp. coronata); its western counterpart, Audubon's warbler (spp. group auduboni); the northwest Mexican black-fronted warbler (spp. nigrifrons); and the Guatemalan Goldman's warbler (spp. goldmani). All subspecies of the yellow-rumped warbler are characterized by the yellow rump as its name implies, while intra-group and inter-group variations in appearance exist in spite of many similarities. The myrtle and Audubon's groups, as two major subspecies, are distinguished by noticeable features such as differing throat colorations. Wikipedia →

Possible
About 20% of wildlife watchers report a Yellow-rumped Warbler sighting in Boston on a given day, based on 8,401 verified sightings from GBIF citizen-science data. It is the 37th most-seen of the 283 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May
In that month about 50% of wildlife watchers report a Yellow-rumped Warbler in Boston on a given day, against under 5% in June–August and December–March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Yellow-rumped Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
39th of 48
Of the 48 cities where we can rate Yellow-rumped Warbler sightings, Boston ranks 39th at about 20%. The best odds are in Toluca (México, about 60%), Mesa (United States, about 60%) and Sacramento (United States, about 60%).
Same genus: Setophaga
The closest relatives of the Yellow-rumped Warbler that you can see in Boston (genus Setophaga, Setophaga Warblers) are Yellow Warbler (about 20%), Northern Yellow Warbler (about 10%) and Northern Parula (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-rumped Warbler is recorded against all the birds logged in Boston (8,401 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.
