Say's phoebe (Sayornis saya) is a passerine bird in the tyrant flycatcher family, Tyrannidae. A common bird across western North America, it prefers dry, desolate areas. It was named for Thomas Say, an American naturalist.

The juvenile is similar to adult, but has buffy orange to whitish wingbars and a yellow gape... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Say's Phoebe is recorded against all the birds logged in Monterrey (104 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.
