Start Date: Saturday, April 19, 2014
Start Time: 7:00 AM

Description: This year Terry will lead a one-day Mines Road trip. Long recognized as one of the premier springtime birding areas in the Bay Area to observe an array of resident species and Neotropical migrants, the combination of Mines Road and Del Puerto Canyon provides easy access to a number of unique habitats, including oak woodland, grasslands and chaparral. The bird list is quite impressive for this popular destination, and includes Costa's Hummingbird, Lewis's Woodpecker, Western Wood-Pewee, Ash-throated Flycatcher, Western Kingbird, Yellow-billed Magpie, Rock Wren, Canyon Wren; Nashville, Orange-crowned, Hermit, Yellow and MacGillivray's warblers; Rufous-crowned Sparrow, Black-headed Grosbeak, Bullock's Oriole, Western Tanager, Wood Duck and Lawrence's Goldfinch, just to name a few. The elusive Greater Roadrunner is reported annually. We'll also visit Del Valle Regional Park (fee) and Frank Raines Park. This all-day trek will start In Livermore on Saturday morning. There are a number of hotels in Livermore for those wishing to spend Friday night and thus eliminate the early Saturday morning departure from home. This is a very popular springtime trip and often fills up very quickly. Sign-ups are required, and are on a first-come, first-served basis. Carpooling is a must as there is very limited space for vehicles to park on Mines Road. To sign-up and receive further details, contact Terry Colborn at:, 530-312-9947;
