摘要: We investigated the nesting success of songbird species breeding in two riparian drainages (Redwood and Lagunitas Creeks) Golden Gate National Recreation Area, Marin County, California. Estimates nest are presented for 14 both drainages. Nest was low majority open-cup contrast to relatively high cavity-nesters. In order guide restoration efforts Redwood Creek we examined structural floristic vegetation characteristics that may influence Warbling Vireo (Vireo gilvus), Swainson's Thrush (Catharus ustulatus), Wilson's Warbler (Wilsonia pusilla), Song Sparrow (Melospiza melodia) using data from 1997 1998 field seasons. Univariate models all four multivariate determine which variables success. System-wide diversity tree species, red alder California bay, were important influencing Nesting substrate preferences five as well combined. blackberry, willow, sword fern, lady elderberry preferences. Management recommendations presented.
