. The birds of California : a complete, scientific and popular account of the 580 species and subspecies of birds found in the state. Birds; Birds. The Williamson Sapsucker Williamson Sapsuckers occur chiefly in pine timber at the middle and upper levels of our higher ranges. They are especially common in the east central Sierras; and although they occupy the same general territory, they shun the quaking asp and other deciduous trees, which are the special province of the Red-breasted Sapsuckers. Except for a rolling call, a rhythmical drumming on wood, which is like a call to arms in the quiet forests, the Williamson Sapsuckers are rather silent birds. Food, which consists chiefly of ants with a little sauce of flying insects and a flavor of sap, is easily obtained. Hence, the birds do not wander far, nor make therr selves very conspicuous. While bird-nesting in the sendee of the M. C. O. in the summer of 1919, I sighted a female of this species, the rather reluctant subject of one of the accompanying illustrations, in a small pine-clad valley near Lake Mary, one of the "Mammoth" group in southern Mono County. We followed her course for some minutes as she sucked sap, first from one pine sapling, then from another; finally she caught a fly midair with a swift fillip, then beat a straight course across the valley and was lost.
