Howell, T.R. 1949 S.V. daggetti Journal 22 Alturas, Modoc Co., Calif May 27 (cont'd.) tests are made before a definitive hole is chosen, as there are usually several fresh looking holes which are left shallow. The holes do not consistently face in any particular di- rection. Both birds seem to participate equally in excavation and incubation. 5 eggs, not 3, seems to be a full clutch. The birds are very quiet most of the time except when disturbed right at the nest. The only way to find them is by luck and by poking around each hole-ridden aspen and watching for a bird to stick its head out. Possibly they are nesting in the pines too but there are so many hole-ridden pine stubs that it will be purely fortuitous if I find any nests in those. The nests are distributed as follows: (NOT TO SCALE: [#s 1,8,6,3 are not so evenly spaced. Aspens are scattered irregu- larly along the creeks) W 5 C.F. Twin Spr. Creek Willow Creek 4 1 8 6 2 7 3
