Daily Postcard: Not a Yellow-bellied Sapsucker but a Sapsucker with a yellow belly! Summertime woodpeckers in Los Alamos County, Williamson’s Sapsuckers prefer deep evergreen forests but make occasional appearances in town. A good place to see them is along the reservoir road in Los Alamos Canyon. The Williamson’s Sapsucker is named after Lt. Col. Robert Williamson, leader of a surveying expedition for the transcontinental railroad in the mid 19th century. Local wildlife photographer Jonathan Dowell, Ph.D. took this photo of the Williamson’s Sapsucker in October at a backyard fountain on Barranca Mesa.
