Marshall, 1947 Melospiza Napa Co. Oct 18 Sisson Creek, Solano Co., Calif.. Stopped several places along creek in good habitat but no water. Open willow thickets, recently dried up Typha, Rose, blackberry etc. No birds. At one place (200 ft Elevation at "Y" 1 mi N Napa Co. Line), saw one bird - was standing water here in creek bed. Rich growth blackberry, nettles, willows. May have been wintering morpina or fislarella however. Along Gordon Creek s.side, gordon Valley Dam (Curry Lake) covered over 1 mile of creek with excellent habitat & found no birds except (one good morphna at Mr. Chadburn's Ranch) morpina & fislerella. Usually these were in Thistle & weeds on dry pasture away from creek, But one or 2 were in blackberry's etc at water edge. The birds must migrate from here. One catch - this creek is permanent & flows out of a year-round spring! Must be an exception which can't upset prevailing habit or genetic trait of birds in this general area to migrate because of streams drying up. This may explain absence of fall birds along Merced R. too. Gordon Creek had Willows, Elders, some lurels (but plenty of open places) Polygonum, blackberry,
