The western kingbird (Tyrannus verticalis) is a large tyrant flycatcher found throughout western North America, as far south as Mexico. Adults are a combination of both gray and yellow plumage, along with crimson feathers that are hidden until courtship or against intruders. Characteristic of kingbird species, the western kingbird is very territorial. Although the western is often misidentified as Cassin's kingbird, Couch's kingbird, or the tropical kingbird due to the yellow coloration, it can be distinguished from these other species through its black, squared tail with white edges.
The breeding habitat is open areas in western North America. The increased presence of trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the range expansion of the western kingbird, as well as range expansions of many other species of birds.
Instances of hybridization with the closely related Eastern Kingbird (Tyrannus tyrannus) have been reported. Hybridization between the two species may become more frequent as the expanding range of the Western Kingbird increasingly... Wikipedia →

Under 5% of wildlife watchers report a Western Kingbird sighting in San José on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 292nd most-seen of the 379 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 Western Kingbird in San José on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Western Kingbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 31 cities where we can rate Western Kingbird sightings, San José ranks 29th at under 5%. The best odds are in Torreón (México, about 20%), Ciudad Juárez (México, about 10%) and San Antonio (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Western Kingbird is recorded against all the birds logged in San José (18 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.
