The California gull (Larus californicus) is a medium-sized gull, smaller on average than the herring gull, but larger on average than the ring-billed gull (though it may overlap in size with both). Although named after California, it can be found annually across most of western North America, from the Canadian prairie provinces in the northeast and south through western Mexico. Wikipedia →

Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
