The American dusky flycatcher (Empidonax oberholseri), or simply dusky flycatcher, is a small insectivorous passerine of the tyrant flycatcher family. The dusky flycatcher is one of many species in the genus Empidonax. These species are very similar in appearance and behavior, and they are notoriously difficult to differentiate. The best characteristics for distinguishing these species are voice, breeding habitat, and range. 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.
