The plumbeous vireo (Vireo plumbeus) is a small North American songbird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found from the U. S. states of Montana and South Dakota south to Honduras.
The plumbeous vireo was originally described in 1866 as Vireo plumbeous, its present binomial. Until the late 1990s it and what are now Cassin's vireo (V. cassinii) and the blue-headed vireo (V. solitarius) were treated as a single species, the "solitary vireo" (V. solitarius sensu lato). Earlier studies had suggested the split based on morphology, plumage, and vocalizations, and molecular genetic studies published in the early 1990s confirmed differences among the three. They form a superspecies.
The plumbeous vireo has these four subspecies: Several other subspecies have been named but have not been confirmed as separate from any of these four. There is some doubt about whether V. plumbeous represents one or two species, and the Clements taxonomy separates them within the species as the "plumbeous" (V. p. plumbeus... Wikipedia →

Rare
Under 5% of wildlife watchers report a Plumbeous Vireo sighting in San Diego on a given day, based on 244 verified sightings from GBIF citizen-science data. It is the 236th most-seen of the 386 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 Plumbeous Vireo in San Diego on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Plumbeous Vireo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 14
Of the 14 cities where we can rate Plumbeous Vireo sightings, San Diego ranks 12th at under 5%. The best odds are in Toluca (México, about 10%), Guadalajara (México, about 10%) and Torreón (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Plumbeous Vireo is recorded against all the birds logged in San Diego (244 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.
