The Northern Flicker is a stunning woodpecker species. They are common in Orange County and can be heard calling and perhaps singing throughout the year though moreso in winter months. They are easily distinguishable with their black polka dot chest over white plumage. They can be seen on the ground or up high in various tree types.
A rare sub species was found today, the Yellow-shafted variation at Oso Reservoir near the 241 toll road and Los Alisos Blvd. The yellow-shafted are for the most part the eastern US variants whereas here in southern California, we have the red-shafted variants.
The differences are typically easy to ID. If the under tail and under wing show a bright orange coloration, then you’ve more than likely seen the “red-shafted” sub species. However if you happen to see a yellow under tail and yellow under wing, this is more than likely the “yellow-shafted” variation.
See the two comparative variants below. The male displays the red malar. This is a red marking within cheek area on the red-shafted variant/sub species. The female does not display “any” malar marking. If the yellow -shafted were a male, the malar would be black in color vs. red.
(Side note: there is an intergrade variant which is hybrid of both the red-shafted and yellow-shafted. Both the yellow-shafted and intergrade are considered rarities for Orange County. The intergrade would display the yellow under tail feathers with a minimal red crescent within the nape area and potentially a grayish head and throat)
