Prairie Warbler
This Prairie Warbler was at Mile Square Regional Park, in Fountain Valley (Orange County), CA, 26 September, 2017 (originally found here on 25 Sept., 2017, by Jim Pike). This species is known as a breeder typically in second-growth, scrubby habitats throughout much of the eastern U.S., although it is a very rare visitor (primarily as a fall migrant) to California. It is one of the many "eastern" North American warblers known to occasionally wander significantly out of range, to the western U.S.; these are often referred to as "vagrants" by birders. Even though a rarity anywhere in the West, over the years Orange County seems to have gotten fewer records of Prairie Warblers than most other So Cal counties.
